This Amendment No. 1 to Schedule 13D supplements, amends and relates to
information in the Schedule 13D originally filed on May 13, 2002 (the "Schedule
13D") by the person filing this amendment. Capitalized terms used in this
Amendment No. 1 to the Schedule 13D not otherwise defined herein have the
meanings ascribed to them in the Schedule 13D. The Schedule 13D is supplemented
and amended by this Amendment No. 1 as follows:

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Item 3 of the Schedule 13D is hereby amended to include the following
information.

         Boston Scientific has the ability to borrow up to approximately $1.6
billion pursuant to (i) a $1.0 billion revolving credit facility entered into on
May 31, 2002 that terminates in May 2003, and (ii) a $600 million revolving
credit facility entered into on August 15, 2001, that terminates in August 2006.
These agreements, filed as exhibits (3) and (4), respectively, to this Amendment
No. 1, and incorporated herein by reference thereto, were entered into in the
ordinary course by Boston Scientific and not specifically for the purpose of the
Offer. Each of the revolving credit facilities is among Boston Scientific and a
syndicate of lenders, the composition of which may change from time to time.

         Each of the $1.0 billion and the $600 million credit facility makes
available to Boston Scientific U.S. dollar denominated loans, Euro dollar loans,
letters of credit, multi-currency loans and local currency loans. The amounts
borrowed under each facility bears a variable interest rate on (i) U.S. dollar
denominated same day loans, based upon the greater of the applicable prime rate,
a specified base CD rate plus 1%, or the Federal Funds Effective Rate plus 0.5%,
and on (ii) Eurodollar denominated loans and multi-currency denominated loans,
based on the rate per annum determined by the credit facility's administrative
agent to be the offered rate for deposits in the applicable currency with a term
comparable to the interest period of such loan plus an applicable margin based
upon Boston Scientific's then current credit rating. Both the $1.0 billion and
the $600 million credit facilities are unsecured and contain customary negative
and affirmative covenants, including financial covenants, conduct of business
covenants, limitations on liens and indebtedness and limitations on fundamental
changes. For more information regarding the Boston Scientific's available
borrowings pursuant to the revolving credit facilities, including any of the
non-U.S. currency loans, please see exhibits (3) and (4) to this Amendment No.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER.

         Item 5 of the Schedule 13D is hereby amended as follows.

         Pursuant to the Merger Agreement, on May 30, 2002, Boston Scientific,
through its wholly owned subsidiary Broadway Acquisition Corp., commenced a
tender offer for all of the issued and outstanding Shares of the Issuer. The
offer expired at 12:00 midnight New York City time, on Wednesday, June 26, 2002.

Based on information provided by The Bank of New York, the depositary for the
tender offer, approximately 9,634,444 Common Shares and 1,114,485 Series A
Shares were tendered. This represents approximately 96.3% of the outstanding
Common Shares on an as converted basis. Boston Scientific, through its
wholly-owned subsidiary Broadway Acquisition Corp., has accepted for payment all
shares validly tendered and not properly withdrawn prior to the expiration of
the tender offer.

Boston Scientific intends to cause Broadway Acquisition Corp. to merge with the
Issuer as soon as practicable. Because Boston Scientific has acquired more than
90% of the outstanding Shares of the Issuer, the merger is expected to be
consummated without a vote or meeting of the Issuer's stockholders. In the
merger, each of the

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


remaining Shares that were not tendered and accepted for exchange in the tender
offer will be converted into the right to receive $6.8426 per Common Share and
$13.6852 per Series A Share in cash, without interest. The Issuer will then
become a wholly owned subsidiary of Boston Scientific.

         Except as set forth herein, to the knowledge of Boston Scientific, no
director or executive officer of Boston Scientific beneficially owns any other
shares of the Issuer.
