                  Application to Withdraw Registration Statement

Ladies and Gentlemen:

     Pursuant to Rule 477 promulgated under the Securities Act of 1933, as
amended (the "1933 Act"), submitted electronically via the EDGAR system,
Integrated Surgical Systems, Inc., a Delaware corporation (the "Company"),
hereby requests the withdrawal of the Company's Registration Statement on Form
S-3 (Registration No.:333-51412) filed with the Securities and Exchange
Commission (the "SEC") on December 7, 2000 (the "Registration Statement").

     The Company has determined that market conditions since that filing have
not been favorable for such an offering and therefore the offering should not
proceed. No securities were sold in connection with the Registration Statement.
The Company respectfully requests, that in accordance with the provisions of
Rule 477(a) under the 1933 Act, the SEC issue an order granting the desired
withdrawal of the Registration Statement.

     If you have any questions or comments with respect to this withdrawal
request, please contact either the Company's counsel, Jack Becker, Esq., of Snow
Becker Krauss P.C., at 605 Third Avenue, New York, New York 10158 (Telephone:

above.

                                            Very truly yours,

                                            Integrated Surgical Systems, Inc.
