     ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

     Late in the afternoon of June 1, 2004, Boston Scientific Corporation (the
"Registrant") and Scimed Life Systems, Inc., a wholly-owned subsidiary of the
Registrant ("Scimed"), completed the acquisition of Advanced Bionics
Corporation, a privately-held company located in Valencia, CA, in accordance
with the terms of the Agreement and Plan of Merger dated May 28, 2004, among the
Registrant, Scimed, Claude Acquisition Corp., a wholly-owned subsidiary of
Scimed, Advanced Bionics Corporation, Bionics Trust and Alfred E. Mann, Jeffrey
H. Greiner, and David MacCullum, collectively in their capacity as the
Stockholders' Representatives (the "Agreement").

     Pursuant to the Agreement, the Registrant acquired 100 percent of the fully
diluted equity of Advanced Bionics for an initial payment of approximately $740
million in cash, plus earn out payments tied to future performance milestones.
The initial purchase price was funded by the issuance of commercial paper.

     The acquisition has been structured to include a substantial earnout
mechanism. Performance milestones are primarily based on the achievement of net
sales, with certain milestone payments also tied to profitability.

     The performance milestones are segmented by the four principal technology
platforms (cochlear implants, implantable pulse generators, drug pumps and bion
microstimulators), each with a 72-month earnout horizon. Base earnout payments
on these performance milestones approximate two and a quarter times incremental
sales for each annual period. There are also bonus earnout payments available
based on the attainment of certain aggregate sales performance targets and a
certain gross margin level.



     ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

     (a) Financial Statements of businesses acquired.

         Financial statements required by this Item 7 will be filed by amendment
         to this report no later than 60 days after the date an initial report
         must be filed with the Securities and Exchange Commission (i.e. on or
         before August 13, 2004).

     (b) Pro forma financial information.

         Pro forma financial information required by this Item 7 will be filed
         by amendment to this report no later than 60 days after the date an
         initial report must be filed with the Securities and Exchange
         Commission (i.e. on or before August 13, 2004).
