                           BOSTON SCIENTIFIC ANNOUNCES
                             SECOND QUARTER RESULTS


Natick, MA (July 22, 2003) -- Boston Scientific Corporation (NYSE: BSX) today
announced financial results for its second quarter ended June 30, 2003.

Net sales for the second quarter were $854 million as compared to $708 million
for the second quarter of 2002, an increase of 21 percent. Excluding the
favorable impact of $40 million of foreign currency fluctuations, net sales were
$814 million, an increase of 15 percent.

Net income for the quarter, excluding net special charges, increased 33 percent
to $126 million, or $0.30 per share (diluted), as compared to $95 million, or
$0.23 per share, excluding net special charges, in the second quarter of 2002.
Reported net income for the quarter, including net special charges of $12
million (after-tax), was $114 million, or $0.27 per share, as compared to
reported net income of $25 million, or $0.06 per share, in the second quarter of
2002.

The net special charges for the quarter include purchased in-process research
and development costs of $12 million (after-tax), or $0.03 per share, related to
acquisitions.

"This was our first full quarter of TAXUS sales in Europe and other
international markets, and we were encouraged by the enthusiastic reception,
which has resulted in our achieving what we believe to be unit market share
leadership in those markets where TAXUS has been launched," said Jim Tobin,
President and Chief Executive Officer of Boston Scientific. "Momentum continues
to build for TAXUS, and we feel this bodes well for our U.S. launch. The quarter
also saw further progress in our TAXUS clinical program, with the filing of our
Pre-Market Application with the FDA and the presentation of strong follow-up
data from three clinical trials and a transitional registry."

Boston Scientific officials will be discussing these and other issues with
analysts on a conference call at 5:30 p.m. (ET) Tuesday, July 22. The Company
will webcast the call to all interested parties through its website:
