                       ----------------------------------

             400,000 SHARES OF SERIES A CONVERTIBLE PREFERRED STOCK

         This Prospectus  covers the proposed offer and sale by Trimedyne,  Inc.
("we",  "us",  "our" or the  "Company") of up to 400,000  shares of its Series A
Convertible  Preferred Stock,  $10.00 par value (the "Preferred  Stock"), to the
public  on a "best  efforts"  basis  from  time to time over a period of six (6)
months from the date of this Prospectus  (unless we and the Underwriter agree to
extend the  offering),  at prices related to the then market price of our Common
Stock.  This  Prospectus  also covers the possible  sale of 40,000 shares of our
Preferred Stock to the public if the Underwriter  exercises the Warrants we sold
to the Underwriter,  as described below, and 55,000 shares of Preferred Stock to
the public if certain  consultants to the Company  exercise the Warrants we sold
to them.  We will  receive  all of the net  proceeds  from the sale of the above
securities.

         Each share of Preferred  Stock is  convertible  into ten (10) shares of
our Common  Stock,  $.01 per value (the  "Common  Stock"),  at the option of the
holder at any time  after  December  31,  2001.  The  Preferred  Stock  shall be
entitled to ten (10) votes per share and to dividends and distributions,  if any
are declared,  in an amount equal to the dividend or distribution  paid, if any,
on ten (10) shares of Common Stock.  The Preferred Stock shall have prior rights
to the assets in the event of our  liquidation  or  dissolution to the extent of
$10 per  share  of  Preferred  Stock,  and the  Preferred  Stock  may be  called
(redeemed)  at our option at any time after  December 31, 2001, at a price equal
to $11 per share of Preferred Stock.

         We  have  agreed  to  pay  the  Underwriter  a  commission  of 7% and a
non-refundable expense allowance of one percent 1% of the sales of the Preferred
Stock to the public, of which $5,000 has already been paid. We have also sold to
the Underwriter at nominal cost 40,000 Warrants  ("Warrants"),  each exercisable
over a period of four (4) years  commencing one year after the Effective Date of
this  Prospectus to purchase shares of Preferred Stock in an amount equal to ten
percent  (10%) of the number of shares of Preferred  Stock sold to the public in
this offering.  To the extent  exercisable,  each Warrant will be exercisable to
purchase  one share of our  Preferred  Stock at an  exercise  price equal to one
hundred  twenty  percent  (120%)  of the  average  monthly  sales  prices of the
Preferred Stock to the public during the offering.  We and the Underwriter  have
also agreed to indemnify  each other in certain  circumstances.  We estimate the
other costs of this offering to us will be approximately  $75,000. (See "PLAN OF
DISTRIBUTION.")

         We have  applied  for  listing  of our  Preferred  Stock on the  NASDAQ
National  Market  System under the symbol  "TMDP." Our Common Stock is traded on

our Common Stock on ____________________ 2001 was $_______ per share.

                                       3



                                   THE COMPANY

         Trimedyne, Inc. (the "Company",  "we", "our" or "us") is engaged in the
development, manufacturing and marketing of Holmium "cold" pulsed lasers, Nd:YAG
"thermal"  continuous  wave  lasers and  proprietary,  disposable  and  reusable
fiber-optic  laser delivery devices which have been cleared for sale by the U.S.
Food and Drug Administration ("FDA") for use in orthopedics,  urology, ear, nose
and  throat  ("ENT")  surgery,  gynecology,  gastrointestinal  surgery,  general
surgery and other medical applications.

         Our 100% owned subsidiary, Mobile Surgical Technologies,  Inc. ("MST"),
is  engaged  in the  rental of  lasers,  along  with the  services  of a trained
operator,  on a "fee  per  case"  basis to  hospitals,  surgery  centers,  group
practices  and  individual  physicians  in Texas,  Oklahoma  and  Louisiana.  We
recently  entered into a letter of intent to acquire  Surgical  Alliance,  Inc.,
which is engaged in a similar "fee per case" laser  rental  business in Alabama,
Georgia and Tennessee. We have also entered into Revenue Sharing Agreements with
other "fee per case" laser rental  companies,  under which we provide our lasers
to them and share in the rental revenues.

         In  addition  to the  use of our  Holmium  lasers  in  orthopedics  for
discectomy and arthroscopy,  and in urology for fragmenting  urinary and biliary
stones,  in  November  2000,  we received  clearance  from the FDA to market our
Holmium laser and fiber-optic  devices in minimally  invasive,  endoscopic laser
foraminoplasty ("ELF") procedures, which orthopedic surgeons can employ to treat
herniated and ruptured lumbar (lower back) spinal discs on an outpatient  basis.
Our Holmium laser and fiber-optic  devices are presently the only laser products
cleared for sale by the FDA for use in such foraminoplasty procedures.

         Approximately 540,000 surgical laminectomy or discectomy procedures are
performed  each in the United States to treat  herniated or ruptured  discs at a
cost of about  $30,000 each or $16.2  billion  annually.  Our  outpatient  laser
discectomy  and ELF procedures to treat  herniated or ruptured  discs  procedure
cost less than  one-half  the cost of the  surgical  procedure,  which  requires
general   anesthesia   and  entails  a  lengthy   hospital   stay,   significant
post-operative pain and a recovery period of several months.

         Our Holmium laser and fiber-optic devices are also presently being used
in a new,  experimental,  endoscopic  Minimally  Invasive  Spinal  Stabilization
procedure to treat degenerated lumbar discs on an outpatient basis.  Traditional
surgical  procedures to treat  degenerated discs require general  anesthesia,  a
lengthy hospital stay,  significant  post-operative  pain, an extensive recovery
period  and a cost  estimated  at two to three  times the  expected  cost of the
outpatient spinal stabilization procedure, if and when the procedure is approved
for  sale by the FDA.  Approximately  400,000  surgical  fusion  procedures  are
performed each year in the United States to treat degenerated discs and diseased
spinal joints at a cost of about $60,000 each or $24 billion.

         We have  also  designed  and  obtained  U.S.  patents  or filed  patent
applications covering several new fiber-optic devices for use in other minimally
invasive surgical applications.  These include disposable devices to treat, on a
minimally invasive,  outpatient basis, such widespread conditions as menorrhagia
(excessive uterine bleeding in women),  benign prostatic  hyperplasia  (enlarged
prostates in men),  gastro-esophogeal reflux disease (severe heartburn),  female
stress urinary incontinence, ear infections in children, and other conditions.

         Our factory and corporate office is located at 15091 Bake Pkwy,  Irvine
California, 92618, at which its telephone number is (949)559-5300.

         We have  applied for the listing of our  Preferred  Stock on the NASDAQ
National  Market  System under the symbol  "TMDP." Our Common Stock is traded on
Nasdaq National Market System under the symbol "TMED".  The closing price of our
Common Stock on ________________, 2001 was $_______ per share.

                                  RISK FACTORS

         An  investment  in the  Preferred  Stock  offered  by  this  Prospectus
involves a high  degree of risk.  You should  carefully  consider  the risks and
uncertainties described below, which may not be the only ones we face. If any of
the following risks actually occur, our business, financial condition or results
of operations could be materially adversely affected. In this event, the trading
price of our common  stock  could  decline  and you may lose all or part of your
investment.

We have incurred substantial losses and anticipate continuing losses

         We  had a  loss  of  $1,033,000  from  operations  and a  net  loss  of
$1,731,000 in the quarter  ended June 30, 2001,  and a net loss of $4,700,000 in
the fiscal year ended September 30, 2000. Though we had net income of $2,750,000
in fiscal  1999,  our income in 1999 was derived from our having  received  $6.5
million in  settlement  of our  lawsuit  against  C.R.  Bard,  Inc.  ("Bard") in
December 1998.  Excluding the settlement from Bard, we would have had a net loss
of  $3,750,000  in fiscal 1999.  We sustained a net loss of $2,538,000 in fiscal
1998. At September 30, 2000 we had an  accumulated  deficit of  $36,441,000.  We
anticipate  continuing to incur losses until we generate  sufficient revenues to
offset  the costs  associated  with  manufacturing  and  marketing  our  current
products,  overhead,  and  the  development  of new  products.  There  can be no
assurance  that we will  ever  operate  profitably.  You  should be aware of the
risks, problems,  delays,  expenses,  and difficulties  encountered by companies
developing  new  medical  technologies,  especially  in view of the  significant
competition that we have and will continue to encounter.

We need the proceeds of this offering

         On  June  30,  2001,  we had  only  $146,000  of  cash  and  marketable
securities  and working  capital of  $4,016,000.  However,  on that date, we had
accounts payable and accrued expenses of $2,780,000. If we are unable to collect
a  significant  portion  of our  $1.2  million  of  accounts  receivable  (after
allowances for bad debts) at June 30, 2001,  sell much of our  approximately  $2
million of goods in inventory  or raise at least $2 million in this  offering to
reduce our accounts payable and fund our ongoing operations, we may be unable to
continue to operate as a going concern.

We may need substantial additional financing

         The development,  testing,  approval,  and marketing of medical devices
require a substantial  amount of funds. We believe our existing  working capital
and the proceeds of this offering, if all of the Preferred Stock we are offering
is sold,  will be sufficient to meet our operating needs and the operating needs
of our 100% owned laser rental subsidiary at least for the next twelve months.

         However,  we may need to obtain  additional  financing  to support  our
operations,  continue the  development of our new products and expand MST's "fee
per case"  rental  service.  Sources of such  financing  may include the sale of
additional  equity  securities  or the sale or licensing of patent  rights.  The
issuance of  additional  shares of Preferred  Stock or Common Stock would dilute
your holdings.  Any inability to obtain additional  financing,  if needed,  will
have a material  adverse effect on us, such as requiring us to reduce or curtail
our operations.

There is no assurance that any or all of the shares will be sold

         The  Underwriter  is offering  our  Preferred  Stock to the public on a
"best  efforts"  basis,  and is not committed to purchase any of the shares.  If
substantially  less than all of the shares of our Preferred  Stock are sold, the
proceeds  may  be  insufficient  to  cover  our  capital  needs  (See  "Plan  of
Distribution").

We may not be able to adjust to rapid technological changes

         We are engaged in an intensely  competitive  industry. In recent years,
the medical laser industry has been characterized by rapid technological change.
There is no  assurance  that our  present  products  may not face  technological
obsolescence,  or that we will be able to  develop,  acquire  licenses  for,  or
obtain  regulatory   approvals  to  market  new  products  and  keep  pace  with
technological advances by our competitors.

We may acquire other entities

         We  recently  entered  into a letter  of  intent  to  acquire  Surgical
Alliance, Inc., which rents lasers, along with a trained operator, on a "fee per
case" basis to  hospitals,  surgery  centers,  group  practices  and  individual
physicians in Alabama,  Georgia and Tennessee.  We may engage in acquisitions of
other  companies and  businesses  and may use our cash reserves or our Preferred
Stock or Common  Stock to pay for these  companies.  If we use our  Preferred or
Common Stock for  acquisitions,  this may result in a dilution of the percentage
of the equity you own. In addition,  acquisitions  may involve  speculative  and
risky  undertakings.  Under Nevada law,  acquisitions do not require shareholder
approval, except when accomplished by merger or consolidation.

There are stock options and warrants that may dilute your ownership

         We have  reserved  a total of  2,600,000  shares  of  Common  Stock for
granting of stock options under our Incentive and Non-Qualified  option plans to
our officers, directors,  employees and consultants.  Also, Warrants to purchase
95,000 shares of our Preferred Stock at exercise prices between $5.00 and $25.00
per share are presently outstanding and exercisable.  If options to purchase all
of  these  shares  were  granted  and all of these  options  and  Warrants  were
exercised,  and if all of the  Preferred  Stock is converted  into Common Stock,
such Common Stock would represent approximately 28% of our presently outstanding
Common  Stock.  We may also grant options in the future at prices below the then
market price of our Common Stock,  although we presently have no intention to do
so.

Our stock price is volatile

         The market prices for securities of medical device companies, including
our Common Stock, have been volatile.  It is likely that the price of our Common
Stock will fluctuate in the future.  Many factors can impact the market price of
our  securities,  such as  announcements  of  technological  innovations  or new
commercial products, FDA clearances or approvals,  distribution agreements,  the
results of pre-clinical testing and clinical trials, the issuance or acquisition
of patents or proprietary rights, changes in sales or earnings,  recommendations
by securities  analysts,  and market conditions in general.  The market price of
our  securities  could  also  be  adversely  affected  by  future  exercises  of
outstanding warrants and options.

We do not anticipate paying any dividends

         We have not paid any dividends in the past and do not anticipate paying
any  dividends  in the  foreseeable  future.  This may  depress the price of our
securities, as a non-dividend paying stock may not appeal to certain investors.

                                       6



We may issue other  Preferred  Stock that could  effect the rights of holders of
our Preferred Stock

         We are authorized to issue  1,000,000  shares of Preferred  Stock.  Our
Board of Directors has broad powers to fix the rights and terms of any Preferred
Stock  without  requiring  shareholder  approval.  The  issuance  of  any of our
authorized  but  unissued  Preferred  Stock could have an adverse  effect on the
rights of the  holders  of the  Preferred  Stock sold in this  offering  and our
Common Stock.

We are subject to extensive government regulation

         Our  business  is  subject  to  extensive  regulation  by the  FDA  and
comparable  regulatory   authorities  of  foreign  countries.   Compliance  with
regulatory  requirements  and obtaining  approvals to test or market new medical
devices is expensive  and time  consuming.  We cannot be assured that we will be
able to meet  all  regulatory  requirements  of the FDA and  other  governmental
authorities  or obtain and maintain  approvals to test and market our present or
new products.  Failing to meet  necessary  government  requirements  will have a
negative impact on our ability to sell our products.

We carry limited liability insurance

         We carry an aggregate of  $6,000,000  of general  liability  insurance.
There  is no  assurance  that we can  maintain  such  insurance  in  force at an
acceptable  cost or that the  amount of such  insurance  will be  sufficient  to
protect  our  assets in the event of  claims by users of our  products  or other
parties.  If court awards  exceeding the amount of such insurance were made, our
assets could be depleted.

We are dependent upon maintaining valid patents and licenses

         There is no  assurance  our  patents  will be upheld if  challenged  in
courts  or that we will be able to  obtain  additional  valid  patents.  We also
cannot  assure  that our  products  do not  infringe  patents  owned by  others,
licenses to which may not be  available  to us. Our  inability  to maintain  our
patents,  avoid  infringement  of patents by others or, in such event, to obtain
licenses  thereto  could  have an  adverse  impact on our  financial  condition,
results of operations or our ability to successfully remain in business.

                                 USE OF PROCEEDS

         The cash  proceeds  that we will  receive  from  this  offering,  after
underwriting  discounts and  commissions  and expenses of the offering,  will be
applied to our general  operating  account and used for  reducing  our  accounts
payable operations,  increasing our marketing and sales efforts, expanding MST's
"fee per case" rental service, and ongoing new product development.

                              PLAN OF DISTRIBUTION

         The  Underwriter  is not  committed  to  purchase  any of the shares of
Preferred Stock we are offering.  As a result, there is no assurance that any or
all of the shares will be sold.  The 400,000  shares of Preferred  Stock will be
offered  on  a  "best   efforts"   basis  by  Chatsworth   Capital,   Inc.  (the
"Underwriter")  from time to time over a period of six (6) months  from the date
of this Prospectus  (unless we and the Underwriter  mutually agree to extend the
offering),  at such  times and in such  amounts  as we and the  Underwriter  may
mutually determine, at prices related to the market price of our Common Stock at
the time of sale,  with a seven  percent  (7%)  commission  to the  Underwriter.
However, no commission will be paid to the Underwriter on sales of our Preferred
Stock to officers, directors or employees of the Company and their affiliates.

         We have  sold the  Underwriter,  for a  nominal  consideration,  40,000
Warrants  exercisable  to purchase  shares of our  Preferred  Stock in an amount
equal to ten percent  (10%) of the number of shares of  Preferred  Stock sold to
the public,  except for sales to our  officers,  directors or employees or their
affiliates  or to  certain  other  parties we refer to the  Underwriter.  To the
extent  exercisable,  each Warrant will be exercisable over a period of four (4)
years, commencing one (1) year from the date of this Prospectus, to purchase one
(1) share of our Preferred Stock at a price equal to 120% of the average monthly
sales prices of our Preferred Stock during this offering.  In addition,  we have
agreed to pay the Underwriter a non-refundable  expense allowance of one percent
(1%) of the sales of our Preferred Stock to the public, of which $5,000 has been
paid.

                             BUSINESS OF THE COMPANY

General

         Our business is briefly described above under "THE COMPANY."

         This  Prospectus is accompanied by our Annual report on Form 10-KSB for
the fiscal year ended  September 30, 2000,  which  document fully sets forth our
business and financial and other information  concerning us as of that date, and
Forms 10-QSB for the quarters ended  December 31, 2000,  March 31, 2001 and June
30, 2001.

Subsequent Events

         We  experienced  the  following  material  changes  to  our  operations
subsequent to the end of our fiscal year,  which are described in more detail in
our Annual Report on Form 10-KSB for the fiscal year ended September 30, 2000:

         (a) On November 27, 2000, we announced clearance from the FDA to market
our  Holmium  laser  and  associated  fiber-optic  delivery  devices  for use in
minimally invasive,  endoscopic laser foraminoplasty  ("ELF") procedures,  which
orthopedic  surgeons may use to treat lower back and leg pain due to a herniated
or ruptured lumbar spinal disc on an outpatient basis. Surgery to

                                       8



treat  herniated or ruptured  discs entails  general  anesthesia,  a substantial
hospital stay,  significant  post-operative  pain, a lengthy recovery period and
substantially greater cost.

         (b) On November 28, 2000,  we announced we are  commencing  to market a
new line of reusable laser arthroscopy  devices which reduce the hospital's cost
per case to an amount significantly lower than most competitive devices.

         (c) On November  30,  2000,  we  announced  the  acquisition  of Mobile
Surgical  Technologies,  Inc.  ("MST"),  a  Dallas,  Texas-based  "fee per case"
service  provider of lasers and trained  operators to hospitals  and  outpatient
surgery centers in Texas, Oklahoma and Louisiana, in exchange for 500,000 shares
of our Common Stock.

         (d) On  December  4, 2000,  we  announced  the  election  of William J.
Schubert, founder and President of MST, as our Vice Chairman and Chief Executive
Officer.

         (e) On May 15,  2001,  we  announced  that we entered  into a Letter of
Intent to merge with Emergent Group Inc.

         (f) On June 26, 2001,  we announced  that the Letter of Intent to merge
with Emergent had been  terminated  due to our  inability to reach  satisfactory
terms.

         (g) On July 18, 2001, we announced that Mr.  Schubert and our President
and Chief Financial Officer,  Shane H. Traveller,  resigned their positions with
the Company.  Our Founder and  Chairman,  Marvin P. Loeb,  resumed the duties of
President and Chief Executive Officer.

         (h) On July 30, 2001, we announced that we had entered into a letter of
intent to acquire Surgical Alliance, Inc., a Birmingham,  Alabama-based "fee per
case"  service  provider  of lasers  and  trained  operators  to  hospitals  and
outpatient surgery centers in Alabama, Georgia and Tennessee.

                                       9


                            DESCRIPTION OF SECURITIES

         Our authorized  capital stock  consists of 30,000,000  shares of Common
Stock, par value $.01, and 1,000,000 shares of Preferred Stock.

Preferred Stock

         Each share of our Series A Convertible  Preferred Stock ($10 par value)
is  convertible  into ten (10) shares of our Common  Stock,  $.01 per value (the
"Common Stock") at the option of the holder at any time after December 31, 2001.
The  Preferred  Stock shall have prior  rights to our assets in the event of our
liquidation or  dissolution  to the extent of $10 per share of Preferred  Stock,
and the Preferred Stock may be called (redeemed) at our option at any time after
December 31, 2001, at a price of $11 per share of Preferred Stock. The Preferred
Stock is not entitled to any pre-emptive rights or anti-dilution  protection and
there is no sinking  fund to retire any of the  Preferred  Stock.  Each share of
Preferred  Stock shall be entitled to ten (10) votes per share,  but there is no
provision for cumulative voting of the Preferred Stock. Holders of the Preferred
Stock shall be entitled to ten (10) times the dividends declared, if any, on the
Common Stock.

Common Stock

         The shares of our Common Stock presently outstanding, and any shares of
our Common  Stock issues upon  conversion  of the  Preferred  Stock sold in this
offering, will be fully paid and non-assessable.  Each holder of Common Stock is
entitled to one vote for each share owned of record on all matters voted upon by
stockholders,  and a majority  vote is  required  for all actions to be taken by
stockholders. In the event we liquidate, dissolve or wind-up our operations, the
holders of the Common  Stock are  entitled  to share  equally and ratably in our
assets, if any, remaining after the payment of all our debts and liabilities and
the  liquidation  preference  of the  Preferred  Stock and any  other  shares of
Preferred Stock that may then be outstanding. The Common Stock has no preemptive
rights,  no  cumulative  voting  rights,  and no  redemption,  sinking  fund, or
conversion provisions.  Since the holders of Common Stock do not have cumulative
voting rights,  holders of more than 50% of the outstanding shares can elect all
of our Directors,  and the holders of the remaining shares by themselves  cannot
elect any Directors.

         Holders of Common Stock are entitled to receive dividends,  if and when
declared by the Board of  Directors,  out of funds  legally  available  for such
purpose,  subject to the dividend and liquidation  rights of any Preferred Stock
that may then be outstanding.

         Our  Articles  of  Incorporation  provide  for  a  staggered  Board  of
Directors,  pursuant to which the Board is divided into three classes (as nearly
equal in number as possible)  with the term of one class expiring each year. The
Articles also provide that the  staggered  Board  provisions  cannot be amended,
altered or repealed except by the vote of not less than two-thirds of our issued
and  outstanding  Common Stock and Preferred Stock which may then be entitled to
vote.

Registration of Additional Shares

         Included in the  Registration  Statement of which this  Prospectus is a
part are the 40,000 shares of Preferred  Stock subject to exercise of the 40,000
Warrants  to  purchase  40,000  shares  of  Preferred  Stock we have sold to the
Underwriter and the underlying  400,000 shares of Common Stock. Also included in
the  Registration  Statement  are 55,000  shares of Preferred  Stock  subject to
exercise of the 55,000  Warrants to purchase 55,000 shares of Preferred Stock we
have sold to certain of our  consultants  and the  underlying  550,000 shares of
Common Stock.

Transfer Agent

         The transfer  agent and registrar  for our  Preferred  Stock and Common
Stock is American  Stock  Transfer & Trust Co., 40 Wall  Street,  New York,  New
York.

                   COMMISSION'S POLICY ON INDEMNIFICATION FOR
                           SECURITIES ACT LIABILITIES

         Article 12 of our  Certificate  of  Incorporation  contains  provisions
relating to the  indemnification  of our  directors  and officers to the fullest
extent permitted by Nevada law.  Section 78.751 of the Nevada Revised  Statutes,
as amended,  authorizes  us to indemnify  any director or officer  under certain
prescribed  circumstances and, subject to certain  limitations,  against certain
costs and expenses,  including  attorneys' fees actually and reasonably incurred
in connection  with any action,  suit, or proceeding,  whether civil,  criminal,
administrative or  investigative,  to which the director is a party by reason of
being our director or a director of our subsidiary, if it is determined that the
director acted in accordance  with the applicable  standard of conduct set forth
in those statutory provisions.

         We may also  purchase  and  maintain  insurance  for the benefit of any
director  or  officer  that may cover  claims  for which we could not  otherwise
indemnify such person.

         Insofar as indemnification for liabilities arising under the Act may be
permitted to our directors,  officers,  and controlling  persons pursuant to the
foregoing provisions,  or otherwise, we have been advised that in the opinion of
the Securities and Exchange  Commission such  indemnification  is against public
policy as expressed in the Act and is, therefore, unenforceable.

                                       11



                                 LEGAL OPINIONS

Item 15. Indemnification of Directors and Officers.
         ------------------------------------------

         Section 78.751 of the Nevada Revised Statutes,  as amended,  authorizes
us to  indemnify  any of our  directors  or officers  under  certain  prescribed
circumstances  and,  subject to certain  limitations,  against certain costs and
expenses,   including  attorneys'  fees  actually  and  reasonably  incurred  in
connection  with  any  action,  suit or  proceeding,  whether  civil,  criminal,
administrative or  investigative,  to which the director is a party by reason of
being one of our directors or officers,  if it is  determined  that the director
acted in accordance  with the applicable  standard of conduct set forth in those
statutory  provisions.  Article 12 of our Certificate of Incorporation  contains
provisions  relating to the indemnification of our directors and officers to the
fullest extent permitted by Nevada law.

         We may also  purchase  and  maintain  insurance  for the benefit of any
director or officer that may cover claims for which we could not indemnify  such
person.

Item 16. Exhibits
         ---------

         The following exhibits are filed with this Registration Statement:

         1 Form of "Best Efforts" Underwriting Agreement

         5 Opinion of Counsel

         23(a) Consent of Independent Auditors

Item 17. Undertakings.
         ------------

         The undersigned Registrant hereby undertakes;

         (1) To file, during any period in which offers or sales are being made,
a  post-effective  amendment  to this  registration  statement  to  include  any
material  information  with respect to the plan of  distribution  not previously
disclosed  in  the  registration  statement  or  any  material  change  to  such
information in the registration statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be

                                      II-1



a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (4) The undersigned  registrant hereby undertakes that, for the purpose
of determining  any liability  under the Securities Act of 1933,  each filing of
the registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities Act of 1934) that is  incorporated  by reference in the  registration
statement  shall be deemed to be a new  registration  statement  relating to the
securities  being offered  therein,  and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof.

         (5)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the Registrant  pursuant to the foregoing  provisions,  or otherwise,
the  Registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the  Act and is,  therefore  unenforceable.  In the  event  that a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses incurred or paid by a director,  officer,  or controlling
person of the  Registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                                      II-2



                                   SIGNATURES

         Pursuant  to the  requirements  of the  Securities  Act  of  1933,  the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing a Registration Statement on Form S-2 and has duly
caused this Amendment to the  Registration  Statement dated January 12, 2001, to
be signed on its behalf by the undersigned,  thereunto duly  authorized,  in the
City of Irvine, State of California, on the 8th day of October, 2001.

          state any material fact required to be stated  therein or necessary to
          make the  statements  therein not  misleading,  and no event will have
          occurred  which  should  have  been  set  forth  in  an  amendment  or


                                     - 2 -


          supplement to the  Registration  Statement or the Prospectus which has
          not been set forth in such an amendment or supplement;  except that no

          conformity  with  written  information  furnished  to the Company with
          respect  to  the  Underwriter  by  or on  behalf  of  the  Underwriter
          expressly   for   inclusion  in  any   Preliminary   Prospectus,   the
          Registration  Statement,  or  the  Prospectus,  or  any  amendment  or
          supplement thereto.

               (iii) Neither the  Commission  nor  the "blue sky" or  securities
          authority  of any  jurisdiction  have issued an order  ("Stop  Order")
          suspending the effectiveness of the Registration Statement, preventing
          or suspending the use of any Preliminary  Prospectus,  the Prospectus,

          Company are Mobile Surgical Technologies,  Inc. and Cardiodyne,  Inc.,
          (the   "Subsidiaries").   The   Company  and  the   Subsidiaries   are
          corporations duly organized,  validly  existing,  and in good standing
          under the laws of their respective jurisdictions of incorporation. The
          Company and the  Subsidiaries  are each duly  qualified to do business
          and  are in  good  standing  in  every  jurisdiction  in  which  their
          ownership,  leasing,  licensing,  or use of property and assets or the
          conduct of their business makes such qualification necessary.

               (v) The  authorized  capital  stock of the  Company  consists  of
          1,000,000 shares of Preferred Stock, none of which have been issued or
          are  outstanding,  and  30,000,000  shares of Common  Stock,  of which
          12,815,510  shares  were  outstanding  on  September  30,  2001.  Each
          outstanding  share of Common Stock and to the knowledge of the Company
          each outstanding share of capital stock of the Subsidiaries is validly
          authorized,  validly issued,  fully paid, and  nonassessable,  has not
          been issued and is not owned or held in  violation  of any  preemptive
          rights of  stockholders,  and to the  knowledge  of the Company in the
          case of the  Subsidiary  are owned of record and  beneficially  by the
          Company or the other  shareholders as scheduled in the Prospectus free

          encumbrances,  stockholders' agreements,  and voting trusts, except as
          otherwise  disclosed  in  the  Prospectus.   There  are  currently  no
          outstanding  options,  warrants,  or  other  rights  calling  for  the
          issuance  of,  any shares of  capital  stock of the  Company or to the
          knowledge  of the Company of the  Subsidiary  or any security or other
          instrument which by their terms are convertible into, exercisable for,
          or  exchangeable  for capital  stock of the Company,  except as may be
          described in the Prospectus.

               (vi) The consolidated  financial  statements of the Company as of
          and for the period ended September,  2000 included in the Registration
          Statement  and the  Prospectus  fairly  present  with  respect  to the
          Company and the Subsidiaries the consolidated  financial position, the
          consolidated   results  of  operations,   and  the  other  information
          purported  to be shown  therein  at the  respective  dates and for the
          respective periods to which they apply. Such financial statements have


                                     - 3 -


          been  prepared  in  accordance  with  generally  accepted   accounting
          principles  consistently applied throughout the periods involved,  are
          correct and complete, and are in accordance with the books and records
          of the Company and the  Subsidiaries.  The accountants whose report on
          the audited  financial  statements  is filed with the  Commission as a
          part of the Registration Statement are, and during the periods covered
          by their  report(s)  included in the  Registration  Statement  and the
          Prospectus were independent  certified public accountants with respect
          to the Company and the Subsidiaries  within the meaning of the Act and
          the Regulations.  Except for the consolidated  financial statements of
          the Company, no other financial statements are required by Form S-2 or
          otherwise  to  be  included  in  the  Registration  Statement  or  the
          Prospectus.

               (vii) There is no litigation,  arbitration or other  governmental
          proceeding (formal or informal), or investigation pending,  threatened
          in writing,  with respect to the Company, the Subsidiaries,  or any of
          their respective operations, businesses, properties, or assets, except
          as  described  in  the   Prospectus.   Neither  the  Company  nor  the
          Subsidiaries  are in violation  of, or in default with respect to, any
          law, rule, regulation,  order, judgment, or decree except as described
          in the Prospectus, nor are the Company or the Subsidiaries required to
          take any action in order to avoid any such violation or default.

               (viii) Neither the Company nor the Subsidiaries have received any
          notice that the  Company,  the  Subsidiaries  or any other party is in
          violation or breach of, or in default with respect to,  complying with
          any material provision of any contract, agreement,  instrument, lease,
          license,  arrangement,  or  understanding  which  is  material  to the
          Company and the Subsidiaries taken as a whole, and each such contract,
          agreement,  instrument, lease, license, arrangement, and understanding
          is in full force and is the legal,  valid,  and binding  obligation of
          the parties  thereto and is enforceable as to them in accordance  with
          its terms.  Neither the Company nor the  Subsidiaries are in violation
          or breach of, or in default with respect to, any material  term of its
          certificate of incorporation (or other charter document) or by-laws.

          applications, trademarks, trademark applications, trade names, service
          marks,  copyrights,  franchises,  and other intangible  properties and

          the Company or the Subsidiaries owns or has pending, or under which it
          is licensed,  are in good standing and to the knowledge of the Company
          uncontested.  Neither the Company nor the  Subsidiaries are aware that
          they  have  infringed,  are  infringing,  or have  received  notice of
          infringement  with respect to asserted  Intangibles of others.  To the
          knowledge of the Company or the Subsidiaries  there is no infringement
          by others of Intangibles of the Company or of the Subsidiaries.

               (x) The Company has all requisite power and authority to execute,
          deliver,  and perform this underwriting  agreement (the  "Agreement").
          All  necessary  corporate  proceedings  of the Company  have been duly
          taken to authorize the execution,  delivery,  and  performance of this
          Agreement by the Company.  This  Agreement  has been duly  authorized,

          Company in  accordance  with its  terms.  No  consent,  authorization,
          approval,  order,  license,  certificate,  or  permit  of or from,  or

          governmental  authority or any court or other  tribunal is required by
          the  Company  for the  execution,  delivery,  or  performance  of this
          Agreement by the Company (except filings under the Act which have been

          only of consents  under "blue sky" or securities  laws which have been
          obtained at or prior to the date of this Agreement).  Except where the

          instrument,  lease,  license,  arrangement  to which the  Company is a

          required for the execution, delivery, or performance of this Agreement
          and (b) the  execution,  delivery,  and  performance of this Agreement
          will not violate,  result in a breach of,  conflict  with any material

          stockholders.  The Preferred Stock and the Common Stock conform to all
          statements relating thereto contained in the Registration Statement or

          the price of any  security  of the  Company,  or which  has  caused or

          Preferred Stock hereunder.

3.   Covenants of the Company.
     ------------------------

          The Company covenants that it will:

               (i) Use its best efforts to cause the  Registration  Statement to
          become  effective as promptly as possible and notify you  immediately,
          and  confirm  such  notice  in  writing,  (A)  when  the  Registration
          Statement and any  post-effective  amendment thereto become effective,
          (B) of the receipt of any comments  from the  Commission  or the "blue
          sky"  or  securities  authority  of  any  jurisdiction  regarding  the
          Registration  Statement,  any post-effective  amendment  thereto,  the
          Prospectus,  or any  amendment or supplement  thereto,  and (C) of the
          receipt  of any  notification  with  respect  to a Stop  Order  or the
          initiation or  threatening  of any  proceeding  with respect to a Stop
          Order.  The Company  will use its best efforts to prevent the issuance
          of any Stop  Order and,  if any Stop  Order is  issued,  to obtain the
          lifting thereof as promptly as possible.

               (ii) During the time when a prospectus  relating to the Preferred
          Stock and the  underlying  Common  Stock is required  to be  delivered
          hereunder  or under  the Act or the  Regulations,  the  Company  shall
          comply so far as it is able with all  requirements  imposed upon it by
          the  Act,  as  now  existing  and  as  hereafter  amended,  and by the
          Regulations,  as from time to time in force,  so far as  necessary  to
          permit the  continuance of sales of or dealings in the Preferred Stock
          in accordance with the provisions  hereof and the  Prospectus.  If, at
          any time when a prospectus relating to the Preferred Stock is required
          to be  delivered  hereunder or under the Act or the  Regulations,  any
          event  shall have  occurred  as a result of which,  in the  reasonable
          opinion of counsel for the Company, the Registration  Statement or the
          Prospectus  as  then  amended  or  supplemented  contains  any  untrue
          statement  of a  material  fact or omits to state  any  material  fact
          required  to be stated  therein or  necessary  to make the  statements
          therein not misleading,  or if, in the opinion of such counsel,  it is
          necessary  at  any  time  to  amend  or  supplement  the  Registration
          Statement or the Prospectus to comply with the Act or the Regulations,
          the Company  will  immediately  notify the  Underwriter  and  promptly
          prepare  and file with the  Commission  an  appropriate  amendment  or
          supplement (in form and substance  satisfactory to the Representative)
          which will  correct  such  statement  or omission or which will effect
          such  compliance  and  will  use its  best  efforts  to have  any such
          amendment declared effective as soon as possible.

               (iii) Deliver without charge to the  Underwriter,  as soon as the
          Registration Statement, or any amendment thereto, becomes effective or
          a  supplement  is  filed,  two  copies  of the  executed  Registration
          Statement,  including exhibits, and any amendment thereto, as the case
          may be, and two copies of any supplement  thereto,  and such number of
          copies of the Prospectus,  the Registration Statement,  and amendments
          and supplements thereto, if any, without exhibits,  as the Underwriter
          may request for the purposes contemplated by the Act.


                                     - 6 -


               (iv) Endeavor in good faith, in cooperation with the Underwriter,
          at or prior to the time the Registration  Statement becomes effective,
          to qualify the  Preferred  Stock for offering and sale under the "blue
          sky" or  securities  laws of such  jurisdictions  as you may designate
          subject to the Company's prior approval;  provided,  however,  that no
          such qualification  shall be required in any jurisdiction  where, as a
          result  thereof,  the  Company  would be subject to service of general
          process or to taxation as a foreign corporation doing business in such
          jurisdiction  to which it is not then  subject.  In each  jurisdiction
          where such qualification  shall be effected,  the Company will, unless
          you agree in writing that such action is not at the time  necessary or
          advisable,  file and make such  statements or reports at such times as
          are or may be required by the laws of such jurisdiction.

               (v) File no amendment or supplement to the Registration Statement
          or Prospectus at any time,  whether before or after the effective date
          of the  Registration  Statement,  unless such filing shall comply with
          the  Act  and  the  Regulations  and  unless  the  Underwriter   shall
          previously  have been advised of such filing and furnished with a copy
          thereof.

               (vi)  Comply  with  all  registration,   filing,   and  reporting
          requirements  of the  Exchange  Act,  which  may from  time to time be
          applicable to the Company.

               (vii) Comply with all provisions of all undertakings contained in
          the Registration Statement.

               (viii)  File  timely  and  accurate  reports  on Form SR with the
          commission  in  accordance  with  Rule 463 of the  Regulations  or any
          successor provision.

               (ix) If the principal stockholders, officers, or directors of the
          Company are required by the "blue sky" or securities  authority of any
          jurisdiction requested by the Underwriter pursuant to Section 3(a)(iv)
          to escrow or agree to restrict the sale of any security of the Company
          owned by them for the  Company to qualify or  register  the  Preferred
          Stock for sale  under the "blue  sky" or  securities  laws of any such
          jurisdiction, cause each such person to escrow or restrict the sale of
          such security on the terms and conditions and in the form specified by
          the securities administrator of such jurisdiction.

4.   Payment of Expenses.
     -------------------

          The  Company  agrees to pay all  expenses in  connection  with (a) the
     preparation,  printing  and filing of the  Registration  Statement  and the
     Prospectus,  including  the cost of all  copies of the  Prospectus  and any
     amendments or supplements thereto supplied to the Underwriter in quantities
     as hereinabove stated, (b) the issuance,  sale,  transfer,  and delivery of
     the Preferred Stock, including any transfer or other taxes payable thereon,
     (c) subject to the  Company's  prior  approval,  the  qualification  of the
     Preferred  Stock and  underlying  Common Stock under state or foreign "blue
     sky" or securities  laws,  including the costs of printing the  preliminary
     and  final  "Blue  Sky  Survey,  " (d)  the  filing  fees  payable  to  the
     Commission,  the National  Association  of  Securities  Dealers,  Inc. (the
     "NASD"),  and the jurisdictions in which such  qualification is sought, and
     (e) the disbursements in connection  therewith relating to all filings with
     the NASD.

5.   Conditions of the Underwriters' Obligations.
     -------------------------------------------

          The  obligation  of the  Underwriter  to offer and sell the  Preferred
     Stock as agent for the Company on a best efforts basis, as provided herein,
     shall be subject,  in its  discretion,  to the  continuing  accuracy of the
     representations  and warranties of the Company contained herein and in each
     certificate and document  contemplated under this Agreement to be delivered
     to the  Underwriter,  as of the date hereof and as of the Closing  Date, to
     the  performance by the Company of its  obligations  hereunder,  and to the
     following conditions:

          (a) The  Registration  Statement shall have become effective not later
     than 6:00 P.M.,  New York City Time,  on or before the date of execution of
     this  Agreement  or such  other date and time as shall be  consented  to in
     writing by the Underwriter.

          (b) At the time this  Agreement is executed  and at the Closing  Date,
     you shall have received the favorable  opinion of Heller,  Horowitz & Feit,
     P.C., counsel for the Company, dated the date of delivery, addressed to the
     Underwriter, to the effect that:

               (i)  The  Company  is  a  corporation  duly  organized,   validly
          existing,  and in good standing under the laws of the State of Nevada.
          The Company is duly  qualified to do business and are in good standing
          in every jurisdiction in which its ownership,  leasing,  licensing, or
          use of property and assets or the conduct of its  business  makes such
          qualification necessary;

               (ii) The  authorized  capital  stock of the  Company  consists of
          1,000,000  shares of  Preferred  Stock,  none of which  are  issued or
          outstanding,   and  30,000,000   shares  of  Common  Stock,  of  which
          12,815,510  shares were issued and  outstanding on September 30, 2001.
          Each outstanding share of Common Stock is validly authorized,  validly
          issued,  fully paid, and  nonassessable,  free and clear of all liens,
          security  interests,  pledges,  charges,  encumbrances,  stockholders'
          agreements,  and voting trusts, except as set forth in the Prospectus.
          Except  as  disclosed  in the  Prospectus,  to the  knowledge  of such
          counsel, there is no commitment, plan, or arrangement to issue, and no
          outstanding  option,  warrant, or other right calling for the issuance
          of, any share of capital stock of the Company or any security or other
          instrument which by its terms is convertible into, exercisable for, or
          exchangeable  for  capital  stock  of the  Company,  except  as may be
          properly described in the Prospectus;

               (iii)  To  the  knowledge  of  counsel,  the  Company  is  not in
          violation  or breach of, or in default  with  respect to, any material
          provision  of its  certificates  of  incorporation  (or other  charter
          document) or by-laws;

               (iv)  The  Company  has all  requisite  power  and  authority  to
          execute,  deliver, and perform this Agreement. All necessary corporate
          proceedings of the Company have been taken to authorize the execution,
          delivery,  and  performance  of this  Agreement by the  Company.  This
          Agreement  has been duly  authorized,  executed,  and delivered by the
          Company,  is the legal,  valid, and binding obligation of the Company,
          and  (subject to  applicable  bankruptcy,  insolvency,  and other laws
          affecting  the  enforceability  of  creditors'  rights  generally)  is
          enforceable as to the Company in accordance with its terms;


                                     - 8 -


               (v)  The  Preferred  Stock  to be  sold  by the  Company  in this
          Offering and the Common Stock underlying the Preferred Stock and those
          of the  Warrants  will be  validly  authorized  and,  when  issued and
          delivered in accordance with this  Agreement,  will be validly issued,

          any preemptive rights of stockholders; and

               (vi) The Registration Statement shall have become effective under
          the Act.  To the  knowledge  of such  counsel,  no Stop Order has been
          issued and no  proceedings  for that purpose have been  instituted  or
          threatened in writing.

          Such  opinions  may  contain  such  qualifications,   exceptions,  and
     assumptions  and may rely upon such  matters  or other  opinions  as may be
     agreed upon by the Underwriters and the counsel rendering the opinion.

          (c) At the Closing Date,  you shall have received a certificate of the
     Chief  Executive  Officer and the Chief  Financial  Officer of the Company,
     dated as of the  Closing  Date,  to the effect  that as of the date of this
     Agreement and as of the Closing Date, the representations and warranties of
     the  Company  contained  herein were and are  accurate,  and that as of the
     Closing Date the obligations to be performed by the Company hereunder on or
     prior thereto have been fully performed.

          (d) All  proceedings  taken in  connection  with the  issuance,  sale,
     transfer and delivery of the Common Stock shall be satisfactory in form and
     substance to the Underwriter.

          (e) The NASD,  upon review of the terms of the public  offering of the
     Common Stock, shall not have objected to the Underwriter's participation in
     such offering.

          Any certificate or other document signed by any officer of the Company
     and  delivered  to the  Underwriter  or  its  counsel  shall  be  deemed  a
     representation  and warranty by the Company hereunder to the Underwriter as
     to the  statements  made  therein.  If any  condition to the  Underwriters'
     obligations  hereunder to be  fulfilled  prior to or at the Closing Date is
     not so fulfilled,  the  Underwriter may terminate this Agreement or, if the
     Underwriter so elects,  in writing waive any such conditions which have not
     been fulfilled or extend the time for their fulfillment.

6.   Indemnification and Contribution.
     --------------------------------

          (a) Subject to the conditions  set forth below,  the Company agrees to
     indemnify and hold harmless the  Underwriter  and its officers,  directors,
     partners,  employee's,  agents,  and counsel,  and each person, if any, who
     controls  the  Underwriters  within the meaning of Section 15 of the Act or
     Section  20(a) of the Exchange  Act,  against any and all loss,  liability,
     claim,  damage,  and  expense  whatsoever  (which  shall  include,  for all
     purposes  of this  Section 6, but not be limited to  reasonable  attorneys'
     fees  and  any  and  all  reasonable  expense  incurred  in  investigating,
     preparing, or defending against any litigation, commenced or threatened, or
     any claim  whatsoever  and any and all amounts  paid in  settlement  of any
     claim or litigation) as and when incurred arising out of, based upon, or in
     connection with (i) any untrue  statement or alleged untrue  statement of a
     material fact contained (A) in the Registration Statement or the Prospectus


                                     - 9 -


     (as  amended  and  supplemented  from time to time),  or any  amendment  or
     supplement  thereto  or  (B)  in  any  application  or  other  document  or
     communication   (in  this  Section  6   collectively   referred  to  as  an
     "application")  executed  by or on  behalf  of the  Company  or based  upon
     written  information  furnished by or on behalf of the Company filed in any
     jurisdiction  in order to qualify the  Preferred  Stock and the  underlying
     Common Stock under the "blue sky" or securities  laws thereof or filed with
     the  Commission  or any  securities  exchange;  or any  omission or alleged
     omission  to  state a  material  fact  required  to be  stated  therein  or
     necessary  to make the  statements  therein  not  misleading,  unless  such
     statement  or omission  was made in reliance  upon and in  conformity  with
     written information furnished to the Company as stated in Section 6(b) with
     respect to you expressly for inclusion in the Prospectus,  or any amendment
     or supplement thereto,  or in any application,  as the case may be, or (ii)
     any breach of any material representation, warranty, covenant, or agreement
     of the Company  contained in this  Agreement.  The  foregoing  agreement to
     indemnify  shall be in addition to any  liability the Company may otherwise
     have, including liabilities arising under this Agreement.

          (b) The Underwriter agrees to indemnify and hold harmless the Company,
     each director of the Company and each officer of the Company who shall have
     signed the  Registration  Statement,  and each other  person,  if any,  who
     controls the Company within the meaning of Section 15 of the Act or Section
     20(a) of the Exchange  Act, to the same extent as the  foregoing  indemnity
     from the Company to the  Underwriter in Section 6(a), but only with respect
     to statements or omissions,  if any, made in the Registration Statement, or
     the  Prospectus  (as from time to time  amended and  supplemented),  or any
     amendment or supplement thereto, or in any application in reliance upon and
     in conformity with written  information  furnished to the Company as stated
     in  this  Section  6(b)  with  respect  to the  Underwriter  expressly  for
     inclusion in any Preliminary Prospectus, the Registration Statement, or the
     Prospectus,  or any amendment or supplement thereto, or in any application,
     as  the  case  may  be;  provided,  however,  that  the  obligation  of the
     Underwriter to provide  indemnity under the provisions of this Section 6(b)
     shall be limited to the amount which  represents  the product of the number
     of shares  of  Preferred  Stock  sold by the  Underwriter  as agent for the
     Company hereunder and the public offering price of the Preferred Stock sold
     by the  Underwriter  to the  public  hereunder.  For all  purposes  of this
     Agreement, the amounts of the Underwriter's  commission,  any concession or
     re-allowance and the information set forth under  "Underwriting"  set forth
     in the Prospectus  constitute the only information  furnished in writing by
     or on behalf of the Underwriter expressly for inclusion in the Registration
     Statement or the Prospectus (as from time to time amended or supplemented),
     or any amendment or supplement thereto, or in any application,  as the case
     may be.

          (c) If any action is brought against the Underwriter or the Company or
     any of their officers, directors,  partners, employees, agents, counsel, or
     controlling persons (an "indemnified  party") in respect of which indemnity
     may be sought  against any other  party  hereto  pursuant to the  foregoing
     paragraphs, such indemnified party or parties shall promptly notify all the
     parties (the "indemnifying  parties") against whom indemnification is to be
     sought in writing of the  institution of such action (but the failure so to
     notify shall not relieve the  indemnifying  parties from any liability they
     may have other than  pursuant to this  Section  6(d)) and the  indemnifying
     parties  shall  promptly  assume the defense of such action,  including the
     employment of counsel  (satisfactory to such indemnified  party or parties)


                                     - 10 -


     and payment of expenses.  Such indemnified  party or parties shall have the
     right to employ its or their own counsel in any such case, but the fees and
     expenses of such counsel shall be at the expense of such indemnified  party
     or parties unless the employment of such counsel shall have been authorized
     in writing by the  indemnifying  parties in connection  with the defense of
     such action or the  indemnifying  parties shall not have promptly  employed
     counsel satisfactory to such indemnified party or parties to have charge of
     the defense of such action or such indemnified  party or parties shall have
     reasonably concluded that there may be one or more legal defenses available
     to it or them or to other  indemnified  parties which are different from or
     additional to those available to one or more of the  indemnifying  parties,
     in any of  which  events  such  fees  and  expenses  shall  be borne by the
     indemnifying  parties and the indemnifying parties shall not have the right
     to direct the defense of such action on behalf of the indemnified  party or
     parties.  Anything in this  paragraph to the contrary  notwithstanding,  no
     indemnifying  party shall be liable for any settlement of any such claim or
     action effected without its written consent.  In addition,  the Company and
     the Selling  Stockholder  agree  promptly to notify the  Underwriter of the
     commencement of any litigation or proceedings against the Company or any of
     its officers or directors in connection  with the sale of the Common Stock,
     the  Registration  Statement,  or  the  Prospectus,  or  any  amendment  or
     supplement thereto, or any application.

          (d)  To  provide  for  just  and  equitable  contribution,  if  (i) an
     indemnified  party  makes a claim for  indemnification  pursuant to Section
     6(a), 6(b), or 6(c) (subject to the limitations thereof) but it is found in
     a final judicial  determination,  not subject to further appeal,  that such
     indemnification  may  not be  enforced  in  such  case,  even  though  this
     Agreement  expressly provides for  indemnification in such case or (ii) any
     indemnified or  indemnifying  party seeks  contribution  under the Act, the
     Exchange Act, or otherwise,  then the Company  (including  for this purpose
     any contribution  made by or on behalf of any director of the Company,  any
     officer  of  the  Company  who  signed  the  Registration  Statement,   any
     controlling person of the Company as one entity and the Underwriter, in the
     aggregate  (including for this purpose any  contribution by or on behalf of
     an indemnified  party) as a second entity,  shall contribute to the losses,
     liabilities,  claims, damages, and expenses whatsoever to which any of them
     may be subject,  so that the  Underwriter is responsible for the proportion
     thereof equal to the Underwriter's  commission on the sale of shares of the
     Preferred Stock hereunder, and the Company is responsible for the remaining
     portion based upon the proceeds received or which may have been received as
     a result of this Offering;  provided,  however, that if applicable law does
     not permit such allocation,  then other relevant  equitable  considerations
     such as the  relative  fault of the  Company  and you in the  aggregate  in
     connection  with the facts  which  resulted  in such  losses,  liabilities,
     claims, damages, and expenses shall also be considered. The relative fault,
     in the case of an untrue statement, alleged untrue statement,  omission, or
     alleged omission,  shall be determined by, whether such statement,  alleged
     statement, omission, or alleged omission relates to information supplied by
     the  Company,  or by you. The Company and you agree that it would be unjust
     and  inequitable if the  respective  obligations of the Company and you for
     contribution  were  determined by pro rata or per capita  allocation of the
     aggregate losses,  liabilities,  claims, damages, and expenses (even if you
     and the other  indemnified  parties  were  treated  as one  entity for such
     purpose)  or by any other  method of  allocation  that does not reflect the
     equitable considerations referred to in this Section 6(e). No person guilty
     of a fraudulent  misrepresentation  (within the meaning of Section 11(f) of
     the Act)  shall be  entitled  to  contribution  from any  person who is not


                                     - 11 -


     guilty of such fraudulent  misrepresentation.  For purposes of this Section
     6(e),  each person,  if any, who controls you within the meaning of Section
     15 of the Act or  Section  20(a)  of the  Exchange  Act and  each  officer,
     director,  partner,  employee,  agent, and your counsel shall have the same
     rights to  contribution  as you, and each person,  if any, who controls the
     Company within the meaning of Section 15 of the Act or Section 20(a) of the
     Exchange  Act,  each  officer  of the  Company  who shall  have  signed the
     Registration  Statement,  and each  director of the Company  shall have the
     same rights to  contribution  as the  Company,  subject in each case to the
     provisions  of this  Section  6(e).  Anything in this  Section  6(e) to the
     contrary  notwithstanding,  no party shall be liable for contribution  with
     respect  to the  settlement  of any claim or action  effected  without  its
     written  consent.  This Section 6(e) is intended to supersede  any right to
     contribution under the Act, the Exchange Act, or otherwise.

7.   Representations and Agreements to Survive Delivery.
     --------------------------------------------------

          All representations,  warranties,  covenants, and agreements contained
     in this  Agreement  shall  be  deemed  to be  representations,  warranties,
     covenants,  and agreements at the Closing Date,  and such  representations,
     warranties.  covenants,  and agreements of the Underwriter and the Company,
     including the indemnity and contribution agreements contained in Section 6,
     shall  remain  operative  and in full  force and effect  regardless  of any
     investigation  made by or on behalf of the  Underwriter or any  indemnified
     person, or by or on behalf of the Company, or any person or entity which is
     entitled  to  be   indemnified   under  Section  6(b),  and  shall  survive
     termination  of this  Agreement  or the delivery of the Common Stock to the
     purchasers thereof.

8.   Effective Date of This Agreement and Termination Thereof.
     --------------------------------------------------------

          (a) This Agreement shall become effective at 10:00 A.M., New York City
     Time,  on the  first  full  business  day  following  the day on which  the
     Registration  Statement becomes  effective.  The Underwriter or the Company
     may prevent this Agreement from becoming effective without liability of any
     party to any other  party,  except  as noted  below in this  Section  8, by
     giving the notice  indicated in Section 8(d) before the time this Agreement
     becomes effective.

          (b) The  Underwriter  shall have the right to terminate this Agreement
     at any time prior to the  Closing  Date by giving  notice to the Company if
     any domestic or international  event,  act, or occurrence has materially in
     disrupted,  or in the  opinion  of the  Underwriter  will in the  immediate
     future materially  disrupt,  the securities markets; or if there shall have
     been a  general  suspension  of,  or a general  limitation  on prices  for,
     trading in securities on NASDAQ; or if there shall have been an outbreak of
     major  hostilities or other  national or  international  calamity;  or if a
     banking moratorium has been declared by a state or federal authority; or if
     a moratorium in foreign  exchange trading by major  international  banks or
     persons  has  been  declared;  or if  there  shall  have  been  a  material
     interruption in the mail service or other means of communication within the
     United  States;  or if the  Company  shall have  sustained  a  material  or
     substantial loss by fire, flood, accident,  hurricane,  earthquake,  theft,
     sabotage,  or other  calamity or malicious  act which,  whether or not such
     loss shall have been insured, will, in the opinion of the Underwriter, make
     it  inadvisable  to proceed with the offering;  or if there shall have been
     such change in the market for the  Company's  securities  or  securities in
     general  or in  political,  financial,  or  economic  conditions  as in the
     judgment of the Underwriter makes it inadvisable to proceed with the public
     offering on the terms contemplated by the Prospectus.


                                     - 12 -


(c)      If the Underwriter elects to prevent this Agreement from
         becoming effective, as provided in this Section 8, or to terminate this
         Agreement, the Underwriter shall notify the Company promptly by
         telephone, telex, or telegram, confirmed by letter. If, as so provided,
         the Company elects to prevent this Agreement from becoming effective or
         to terminate this Agreement, the Company shall notify the Underwriter
         promptly by telephone, telex, or telegram, confirmed by letter.

Gentlemen:

         As counsel for your  Company,  we have  examined  your  certificate  of
incorporation,   by-laws,  and  such  other  corporate  records,  documents  and
proceedings  and such questions of laws we have deemed  relevant for the purpose
of this opinion.

         We have also, as such counsel, examined the Registration Statement (the
"Registration Statement") of your Company on Form S-2, covering the registration
under the  Securities  Act of 1933 of up to 400,000  Shares of Preferred  Stock,
$10.00  par  value,  of the  Company  ("Preferred  Stock")  and  the  underlying
4,000,000 shares of Common Stock, $0.01 par value ("Common Stock").

         Our review has also  included the exhibits and form of  prospectus  for
the issuance of such securities (the  "Prospectus")  filed with the Registration
Statement.

         On the basis of such examination, we are of the opinion that:

         1. The Company is a corporation  duly  authorized and validly  existing
and in good standing under the laws of the State of Nevada, with corporate power
to conduct its business as described in the Registration Statement.

         2. The Company has an authorized capitalization of 30,000,000 shares of
Common Stock and 1,000,000 shares of Preferred Stock.

         3. The Preferred  Stock and the underlying  Common Stock have been duly
and validly authorized and, upon the issuance thereof,  will be duly and validly
issued as fully paid and non-assessable.

         We hereby consent to the use of our name in the Registration  Statement
and  Prospectus  and we also consent to the filing of this opinion as an exhibit
thereto.

                                            Very truly yours,



                                            HELLER, HOROWITZ & FEIT, P.C.



                                                             Exhibit 23 (a)

                       CONSENT OF INDEPENDENT ACCOUNTANTS

We  hereby  consent  to  the   incorporation  by  reference  in  the  Prospectus
constituting  a part of this  Registration  Statement  on Form S-2 of our report
dated January 3, 2001 appearing on page F-2 of the Trimedyne, Inc. Annual Report
on Form 10-KSB for the year ended September 30, 2000.
