EXHIBIT 99.1
                                                                    ------------


    STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER OF BOSTON SCIENTIFIC
 CORPORATION REGARDING FACTS AND CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS

I, James R. Tobin, state and attest that:

    (1)     To the best of my knowledge, based upon a review of the covered
            reports of Boston Scientific Corporation, and, except as corrected
            or supplemented in a subsequent covered report:

            *   no covered report contained an untrue statement of a material
                fact as of the end of the period covered by such report (or in
                the case of a report on Form 8-K or definitive proxy materials,
                as of the date on which it was filed); and

            *   no covered report omitted to state a material fact necessary to
                make the statements in the covered report, in light of the
                circumstances under which they were made, not misleading as of
                the end of the period covered by such report (or in the case of
                a report on Form 8-K or definitive proxy materials, as of the
                date on which it was filed).

    (2)     I have reviewed the contents of this statement with the Company's
            Audit Committee.

    (3)     In this statement under oath, each of the following, if filed on or
            before the date of this statement, is a "covered report":

            *   Annual Report on Form 10-K for the year ended December 31, 2001
                filed on March 27, 2002;

            *   all reports on Form 10-Q, all reports on Form 8-K and all
                definitive proxy materials of Boston Scientific Corporation
                filed with the Commission subsequent to the filing of the Form
                10-K filed above; and

            *   any amendments to any of the foregoing.


       /s/ James R. Tobin                                 August 9, 2002
