        Pursuant to Rule 13d-2(c) under the Securities Exchange Act of 1934,
   this Amendment No. 4 to Schedule 13D amends and restates the entire text of
   the Schedule 13D, as previously amended, previously filed by Thermo
   Electron Corporation and Thermedics Inc. relating to shares of Common
   Stock, par value $0.10 per share, of Thermo Cardiosystems Inc.

   Item 1.  Security and Issuer.

        This Amendment relates to the shares (the "Shares") of common stock,
   par value $0.10 per share, of Thermo Cardiosystems Inc. (the "Issuer").
   The Issuer's principal executive offices are located at 470 Wildwood
   Street, Woburn, Massachusetts 01888.

   Item 2.  Identity and Background.

        This Amendment is being filed by Thermo Electron Corporation ("Thermo
   Electron") and its subsidiary Thermedics Inc. ("Thermedics" and, together
   with Thermo Electron, the "Reporting Persons").  The Reporting Persons are
   filing this Amendment pursuant to Rule 13d-2 to reflect an increase in the
   Reporting Persons' holdings of the Issuer's Shares since the Reporting
   Persons' last filing on Schedule 13D, in February 1996, of more than one
   percent. 

        The principal business address and principal office address of Thermo
   Electron, a Delaware corporation, is 81 Wyman Street, Waltham,
   Massachusetts 02254 and the principal business address and principal office
   address of Thermedics, a Massachusetts corporation, is 470 Wildwood Street,
   Woburn, Massachusetts 01888.

        Thermo Electron develops, manufactures and markets environmental,
   analytical and process control instruments, cogeneration and
   alternative-energy power plants, low-emission combustion systems, paper and
   waste-recycling equipment, and biomedical products.  Thermo Electron also
   provides a range of services including environmental remediation and
   consulting, laboratory analysis, and metals fabrication and processing, as
   well as research and product development in unconventional imaging,
   adaptive optics, and direct energy conversion.

        Thermedics develops, manufactures, and markets product quality
   assurance systems, precision weighing and inspection equipment,
   electrochemistry and microweighing products, electronic test instruments,
   explosives-detection devices, and moisture-analysis systems, as well as
   implantable heart-assist devices and other biomedical products. 

        Appendix A attached to this Amendment sets forth with respect to each
   executive officer and director of the Reporting Persons his or her
   (a) name; (b) residence or business address; (c) present principal
   occupation or employment and the name, principal business and address of
   any corporation or other organization in which such employment is
   conducted; and (d) citizenship.  To the knowledge of the Reporting Persons,
   there is no person who may be deemed to be a controlling person of the
   Reporting Persons (except that Thermo Electron may be deemed to control
   Thermedics by virtue of its majority ownership).
PAGE
<PAGE>





        During the last five years, neither the Reporting Persons nor (to the
   knowledge of the Reporting Persons) any executive officer or director of
   the Reporting Persons have been convicted in a criminal proceeding
   (excluding traffic violations and similar misdemeanors).

        During the last five years, neither the Reporting Persons nor (to the
   knowledge of the Reporting Persons) any executive officer or director of
   the Reporting Persons has been a party to a civil proceeding of a judicial
   or administrative body of competent jurisdiction which resulted in a
   judgment, decree or final order (i) enjoining future violations of, or
   prohibiting or mandating activities subject to, federal or state securities
   laws or (ii) finding a violation with respect to such laws.

   Item 3.  Source and Amount of Funds or Other Consideration.

          The Reporting Persons have expended a total of $1,218,600 in
   purchasing Shares of the Issuer since the date of their last filing on
   Schedule 13D, in February 1996. These funds were paid out of the Reporting
   Persons' working capital.

        In addition, on May 2, 1997, Thermo Electron sold one of its
   wholly-owned subsidiaries, International Technidyne Corporation, to the
   Issuer in exchange for the right to receive 3,355,705 Shares of the
   Issuer's Common Stock.  Before these Shares will be issued to Thermo
   Electron, they are to be listed on the American Stock Exchange, Inc.  The
   listing is subject to the approval of the Issuer's shareholders.

   Item 4.  Purpose of Transaction

        Thermedics may make additional purchases of Shares or other securities
   of the Issuer in such manner and in such amounts as it determines to be
   appropriate in order to maintain at least 50% ownership of the Issuer or
   for other purposes.  The Reporting Persons may also make additional
   purchases of Shares or other securities of the Issuer in such manner and in
   such amounts as they determine to be appropriate for other purposes.  In
   determining whether to do so for other purposes, they will consider various
   relevant factors, including their evaluation of the Issuer's business,
   prospects and financial condition, amounts and prices of available
   securities of the Issuer, the market for the Issuer's securities, other
   opportunities available to the Reporting Persons and general market and
   economic conditions.  Purchases may be made either on the open market or
   directly from the Issuer.

        Except as set forth in this Item 4 and in Item 6, neither of the
   Reporting Persons nor, to the Reporting Persons' knowledge, any of the
   executive officers or directors of the Reporting Persons has any current
   plans or proposals which relate to or would result in any of the actions
   specified in clauses (a) through (j) of Item 4 of Schedule 13D, although
   the Reporting Persons and such other persons do not rule out the
   possibility of effecting or seeking to effect any such actions in the
   future.

   Item 5.  Interest in Securities of the Issuer.

        (a)  The Shares beneficially owned by the Reporting Persons include
   19,757,612 Shares, or approximately 54.1% of the outstanding Shares, owned
   by Thermedics, and 3,401,308 Shares, or approximately 8.4% of the
   outstanding Shares, owned by Thermo Electron.  To the knowledge of the
   Reporting Persons, the executive officers and directors of the Reporting
   Persons beneficially own an aggregate of 467,874 Shares or approximately
   1.3% of the outstanding Shares.  To the knowledge of the Reporting Persons,
   the Shares beneficially owned by all executive officers and directors of
   the Reporting Persons include 328,280 Shares that such persons have the
   right to acquire within 60 days through the exercise of stock options.
   Ownership information for each executive officer and director of the
   Reporting Persons who owns Shares is set forth below.

   (1)  Shares reported as beneficially owned by Mr. Crisp, Mr. Ferrari, Dr.
   Fine, Dr. Gyftopoulos, Mr. Jungers, Mr. Keiser, Mr. McCabe, Dr. Morris, Mr.
   Noble, Ms. Olayan, Mr. Poirier, Mr. Smith, Mr. Wellington, Mr. Wood, Dr.
   Zervas and all directors and current executive officers as a group include
   24,750, 2,250, 1,530, 14,500, 11,250, 15,750, 11,250, 11,250, 11,250,
   11,250, 125,850, 30,000, 11,250, 33,450, 12,700 and 328,280 Shares,
   respectively, that such person or member of the group has the right to
   acquire within 60 days.  

   While certain directors and executive officers of the Reporting Persons are
   also directors or executive officers of the Issuer, all such persons
   disclaim beneficial ownership of the Shares owned by the Reporting Persons.

        (b)  The Reporting Persons and the executive officers and directors of
   the Reporting Persons have the sole power to vote and dispose of the Shares
   each such person owns, except that (i) 11,250 of the Shares that are
   beneficially owned by Mr. Paul F. Ferrari are held in a trust of which he
   is the trustee; (ii) 1,122 of the Shares that are beneficially owned by Mr.
   John W. Wood, Jr. are held by Mr. Wood as custodian for two children, (iii)
   19,000 of the Shares that are beneficially owned by Dr. Nicholas T. Zervas
   are held by Dr. Zervas' spouse; and (iv) 6,874 of the Shares that are
   beneficially owned by Dr. Zervas are allocated to Dr. Zervas' account
   maintained pursuant to the Issuer's deferred compensation plan for
   directors.  Thermo Electron owns more than 50% of the outstanding common
   stock of Thermedics and, therefore, may be deemed to have the power to vote
   and dispose of the Shares owned by Thermedics.  However, Thermo Electron
   disclaims the existence of a group between itself and Thermedics for
   purposes of this Schedule 13D.

        (c)  During the past 60 days, the Reporting Persons effected no
   transactions with respect to the Shares.  To the knowledge of the Reporting
   Persons, no executive officer or director of the Reporting Persons has
   effected any transactions in the Shares in the past 60 days

        (d)  Not applicable.

        (e)  Not applicable.

   Item 6.   Contracts, Arrangements, Understandings or Relationships with 
             respect to Securities of the Issuer.

        Of the 19,757,612 Shares beneficially owned by Thermedics, 9,000
   Shares are subject to options to acquire such Shares granted by Thermedics
   pursuant to its director and employee stock option plans.  Of the 3,401,308
   Shares beneficially owned by Thermo Electron, (i) 3,355,705 Shares are
   issuable in connection with the sale by Thermo Electron to the Issuer of
   International Technidyne Corporation, as described in Item 3, and (ii)
   159,290 Shares are subject to options to acquire such Shares granted by
   Thermo Electron pursuant to its director and employee stock option plans.
   The executive officers and directors of the Reporting Persons have the
   right, pursuant to such options, to acquire 117,750 Shares.  In addition,
   the following executive officers and directors of the Reporting Persons
   have the right to acquire Shares from the Issuer pursuant to the Issuer's
PAGE
<PAGE>





   director and employee stock option plans:  Mr. Peter O. Crisp has the right
   to acquire 22,500 Shares within 60 days; Dr. Elias P. Gyftopoulos has the
   right to acquire 3,250 Shares within 60 days, Mr. David H. Fine has the
   right to acquire 1,530 Shares within 60 days, Mr. Victor L. Poirier has the
   right to acquire 125,850 Shares within 60 days, Mr. John W. Wood, Jr. has
   the right to acquire 33,450 Shares within 60 days; Mr. John T. Keiser has
   the right to acquire 11,250 Shares within 60 days; and Dr. Nicholas T.
   Zervas has the right to acquire 12,700 Shares within 60 days.

        During 1996, the Human Resources Committee of the Board of Directors
   of the Issuer (the "Committee") established a stock holding policy for
   executive officers of the Issuer.  The stock holding policy specifies an
   appropriate level of ownership of the Issuer's Common Stock as a multiple
   of the officer's compensation.  For the chief executive officer, Victor L.
   Poirier, the multiple is one times his base salary and reference bonus for
   the calendar year.  For all other officers, the multiple is one times the
   officer's base salary.

        In order to assist officers in complying with the policy, the
   Committee also adopted a stock holding assistance plan under which the
   Issuer is authorized to make interest-free loans to officers to enable them
   to purchase shares of the Common Stock in the open market.  The loans are
   required to be repaid upon the earlier of demand or the fifth anniversary
   of the date of the loan, unless otherwise authorized by the Committee.  

        The Committee also adopted a policy requiring its executive officers
   to hold shares of the Issuer's Common Stock acquired upon the exercise of
   stock options granted by the Issuer.  Under this policy, executive officers
   are required to hold one-half of their net option exercises over a period
   of five years.  The net option exercise is determined by calculating the
   number of shares acquired upon exercise of a stock option, after deducting
   the number of shares that could have been traded to exercise the option and
   the number of shares that could have been surrendered to satisfy tax
   withholding obligations attributable to the exercise of the options.

        During 1996, the Committee also established a stock holding policy for
   directors, including persons who are also directors or executive officers
   of the Reporting Persons (Elias P. Gyftopoulos, Victor L. Poirier, John W.
   Wood, Jr., and Nicholas T. Zervas).  The stock holding policy requires each
   director to hold a minimum of 1,000 shares of Common Stock.  

        In addition, the Committee adopted a policy requiring directors to
   hold shares of the Issuer's Common Stock equal to one-half of their net
   option exercises over a period of five years.  The net option exercise is
   determined by calculating the number of shares acquired upon exercise of a
   stock option, after deducting the number of shares that could have been
   traded to exercise the option and the number of shares that could have been
   surrendered to satisfy tax withholding obligations attributable to the
   exercise of the option.
