Exhibit 10

                      AGREEMENT AND PLAN OF REORGANIZATION

         THIS AGREEMENT and Plan of Reorganization  ("Agreement") is dated as of
the 17th day of August, 2000, by and among TRIMEDYNE, INC., a Nevada corporation
whose office address is 2801 Barranca Road, Irvine,  California (herein referred
to as "Trimedyne"), and Mobile Surgical Technologies,  Inc., a Texas corporation
whose principal office address is 3831 Royal Lane,  Dallas,  Texas 75229 (herein
referred to as "MST"),  and STEPHEN A.  ANDERSON AND WILLIAM J.  SCHUBERT,  JR.,
whose  addresses  are shown on the  signature  page  hereto  and who are  herein
jointly referred to as the "Stockholders".

                                    RECITALS

         A.  Trimedyne  desires to acquire  from the  Stockholders  one  hundred
percent  (100%) of the shares of common stock (the  "Shares") of MST in exchange
for Trimedyne  common stock in the amount and upon the terms and  conditions set
forth herein, and

         B. The  parties  hereto  desire to set forth  certain  representations,
warranties and covenants made by each other as an inducement to the exchange.

         NOW,  THEREFORE,  in  consideration  of the  promises and of the mutual
representations,  warranties and covenants herein contained,  the parties hereby
agree as follows:


                                    SECTION 1
                                EXCHANGE OF STOCK

         1.1  Exchange.  Subject to the terms and  conditions  herein and at the
closing  provided  for in Section 1.5 below (the  "Closing"),  the  Stockholders
shall endorse,  assign, transfer and deliver to Trimedyne all of their shares of
MST stock,  representing all the issued and outstanding shares of MST stock. The
transfer of the Shares to Trimedyne  shall  transfer to Trimedyne full ownership
of all of the personal,  real and intellectual property known as the business of
MST (the  "Business"),  subject to  existing  liens  thereon.  On the same date,
Trimedyne  shall  issue and  deliver  to the  Stockholders  the number of common
voting shares of the capital stock of Trimedyne as determined in accordance with
Section 1.3 below. Such stock shall be divided between and registered to the two
Stockholders in the percentages  set forth following their  respective  names on
the signature page hereto.

         1.2  Registration of Stock.  Prior to the Closing Date,  Trimedyne will
register under the Securities  Act of 1933 and  amendments  thereto,  at its own
expense, the shares of common voting stock to be delivered at the closing.

         1.3  Exchange  Price.  Provided the Closing (as that term is defined in
paragraph  1.5 below)  occurs on or prior to January  15,  2001,  the  aggregate
market  price of the  Trimedyne  stock to be  exchanged  will be One  Million US
Dollars  ($1,000,000).  In the event,  however, that the Closing is delayed past
January 15, 2001,  then the aggregate  market price of the Trimedyne stock shall
be $1,000,000 plus the sum of all principal paid on equipment purchase and lease
obligations  of MST during  the  period  from  January  15,  2001 to the date of



Closing.  The number of shares of Trimedyne's  Common Stock that shall be issued
to the  Stockholders  shall be determined by dividing the total  exchange  price
(that is One Million Dollars, and in the event Closing is delayed, then plus the
principal  payment  reductions  described above) by the average closing price of
Buyer's  Common Stock on the Nasdaq  National  Market System during the five (5)
trading  days  prior to the  Closing  Date of this  transaction.  In the  event,
however,  that the average  closing  price so  determined is less than $2.00 per
share,  for purposes of this  exchange,  the shares shall be valued at $2.00 per
share and the exchange shall be effected accordingly unless the Stockholders, in
their sole  discretion  and option,  then elect and notify  Trimedyne in writing
that they will not accept  the  Trimedyne  stock by reason of such lower  market
price.  In such  event,  this  Agreement  and  Plan of  Reorganization  shall be
thereupon terminated and become null and void.

         1.4 Liabilities and Obligations Assumed. Trimedyne shall assume any and
all liabilities of MST which are a specific obligation of the Business,  whether
fixed,  contingent  or  unliquidated,  as  part of the  exchange  consideration.
Without  limiting  the  foregoing,  Trimedyne  does not  assume and shall not be
obligated to pay or satisfy any  obligation,  debt or  liability,  contingent or
otherwise,  of MST,  arising  out of  fraud,  misrepresentation,  illegal  acts,
malpractice  or  malfeasance  occurring at any time from the  inception of MST's
business up to and  including  the time of  Closing,  or which is not a specific
obligation of the Business.

         1.5 Closing and Delay.  The closing of the stock exchange  provided for
herein  (the  "Closing")   shall  take  place  on  the  effective  date  of  the
registration  statement  covering  the  Trimedyne  Stock  to be  issued  to  the
Stockholders, but not later than January 15, 2001 if the conditions set forth in
Sections 4 and 5 have been  satisfied,  or as soon thereafter as such conditions
have  either  been  satisfied  or  waived  by the  party  benefiting  from  such
conditions  (the  "Closing  Date").  The  Closing  shall  be at the  offices  of
Trimedyne  or at such  other  place as the  parties  shall  agree  and  shall be
effective as of 12:01 a.m. on the Closing Date.

         If Closing does not occur,  for any reason,  on or prior to January 15,
2001,  the Exchange  Price (as defined in paragraph  1.3 above) shall  thereupon
increase in the amount of $50,000.  Further,  if Closing has not  occurred on or
prior to the 15th day of each third (3rd) month  thereafter,  the Exchange Price
shall further  increase each quarter by Fifty  Thousand  Dollars  ($50,000) more
than the preceding payment (that is $100,000 on April 15, 2001, $150,000 on July
15, 2001,  and so on).  Provided the price of Trimedyne  stock as  determined in
accordance  with the  provisions  in paragraph  1.3 above is at closing not less
than $2.00 per share, additional shares shall then be issued equivalent in value
to the applicable  price increase.  In the event,  however,  the Trimedyne stock
price,  determined  as above  provided,  is less  than  $2.00  per share and the
Stockholders  have  nevertheless  elected  to  accept  the  Trimedyne  stock and
complete this exchange  transaction,  then, in such event,  all applicable price
increases accrued in accordance with this paragraph 1.5 shall instead be paid in
cash at Closing. Such amounts paid to the Stockholders shall be divided and made
to them in the percentages set forth  following  their  respective  names on the
signature page hereto.

               its activities  makes such  qualification  necessary,  except for
               failures to be so qualified  that would not,  individually  or in
               the aggregate, have, or would not reasonably be expected to have,
               a Material  Adverse  Effect.  The shares of MST stock  issued and
               delivered pursuant to this Agreement are duly authorized and will
               be, when so issued,  (a) validly issued and outstanding,  and (b)
               fully paid and nonassessable.

               (d) The Stockholders shall have delivered to Trimedyne's  counsel
               all of MST's Shares, duly endorsed in blank or with duly executed
               stock  powers,  or  a  duly  executed   Affidavit  and  Indemnity
               Agreement  for  Lost   Certificates,   in  form  satisfactory  to
               Trimedyne's counsel.


                                    SECTION 6
                                 INDEMNIFICATION

         6.1 Stockholders'  Indemnification.  The Stockholders  hereby agrees to
indemnify and hold  harmless  Trimedyne,  and any person or entity  controlling,
controlled by or under common control with  Trimedyne,  from and against any and
all claims,  damages,  liabilities,  losses and expenses  (including  reasonable
attorneys'  fees)  resulting from or arising out of (i) any breach by MST of any
covenant,  representation,  warranty  or  obligation  of MST  contained  in this
Agreement or any agreement executed in connection with this Agreement,  (ii) any
liability  or  obligation  for any injury to person or property  arising from or
relating to the use or misuse of MST equipment prior to the Closing Date.

         6.2 Trimedyne's  Indemnification.  Trimedyne hereby agrees to indemnify
and hold harmless the Stockholders from and against any and all claims, damages,
liabilities,   losses  and  expenses  (including   reasonable  attorneys'  fees)
resulting  from or  arising  out of any  breach by  Trimedyne  of any  covenant,
representation, warranty or obligation of Trimedyne contained in this Agreement.

         6.3  Notice  of  Claim.  The  party to be  indemnified  hereunder  (the
"Indemnified  Party")  shall  notify  in  writing  (such  notification  shall be
referred  to  herein  as  a  "Claims  Notice")  the   indemnifying   party  (the



"Indemnifying  Party")  within  (i) 60 days  after a claim is  presented  to the
Indemnified  Party or the Indemnified  Party becomes aware of substantial  facts
that would reasonably  appear to the Indemnified Party to be likely to give rise
to a claim for  indemnity  hereunder,  or (ii) five (5) days if the  Indemnified
Party receives  formal notice of the filing of a suit,  petition or claim or the
scheduling  of a hearing  related  to a matter  which may give rise to claim for
indemnity hereunder. Each Claims Notice shall, if feasible, contain a reasonable
estimate by the Indemnified Party of the losses, costs, liabilities and expenses
(including,  but not limited to, costs and expenses of litigation and attorneys'
fees) which the  Indemnified  Party may incur.  If Trimedyne is the  Indemnified
Party  and  delivers  a Claims  Notice  to the  Stockholders,  and the  Stock of
Trimedyne described in Section 1.3 has not yet been issued, Trimedyne shall have
the right to escrow an amount of its Stock  equal to the  amount  claimed in the
Claims Notice.  The Stock shall be released from escrow and either  delivered to
the  Stockholders or retained by Trimedyne  depending on the final resolution of
such  situation.  Such escrow shall be established  with a bank or title company
acceptable  to Buyer and Seller,  with neither  party  unreasonably  withholding
their consent.

         The  Indemnifying  Party  shall  have the  right to  defend a claim and
control the defense,  settlement and  prosecution of any  litigation;  provided,
however,  in order to have the right to defend a claim and control the  defense,
settlement and prosecution of any litigation,  the  Indemnifying  Party (i) must
expressly  acknowledge the assumption by it of all  liabilities  related to such
litigation,  including without limitation, the cost of such defense,  settlement
and  prosecution  of such  litigation,  and (ii)  unless the  Indemnified  Party
consents  otherwise in writing,  may only  compromise or settle such  litigation
solely for money damages for which the Indemnifying Party shall be fully liable.
If the Indemnifying Party fails to defend such claim, the Indemnified Party will
(upon further notice to the Indemnifying  Party) have the right to undertake the
defense,  compromise  or  settlement of such claim on behalf and for the account
and risk of the Indemnifying  Party. The Indemnifying  Party will make available
to the Indemnified  Party or its  representatives,  at the Indemnifying  Party's
expense,  all records and other materials in the Indemnifying Party's possession
and  all  employees  or  agents  of  the  Indemnifying  Party  required  by  the
Indemnified Party for the Indemnified  Party's use in contesting any such claim,
and the Indemnified Party and its  representatives  agree that they will not use
the Indemnifying  Party's making available to them of any such material,  or its
agreement to do so, as a basis for asserting a waiver by the Indemnifying  Party
of any statutory or common law privilege  the  Indemnifying  Party might have in
any other proceedings, whether related or unrelated to the matter giving rise to
the claim. If the Indemnified Party fails to notify the Indemnifying  Party of a
claim in  accordance  with the terms of this Section  6.3, and the  Indemnifying
Party is thereby materially  prejudiced by such failure of notice in its defense
of the claim, the Indemnifying  Party's obligation to indemnify  hereunder shall
be extinguished  with respect to such claim to the extent that the  Indemnifying
Party has been  prejudiced  by the  failure to give such  notice.  The amount of
losses for which  indemnification  is provided under this Agreement shall be net
of any amounts  recovered by the Indemnified  Party under insurance  policies or
from unaffiliated third parties with respect to such losses.



                                    SECTION 7
                             ARBITRATION OF DISPUTES

arbitrator(s) may be entered in any court having jurisdiction thereof. The place
of the arbitration shall be Orange County, California. Each party shall bear its
