FDA APPROVES PROMUS EVEROLIMUS-ELUTING CORONARY STENT.

Boston Scientific Corporation (NYSE:BSX), Natick, Mass. has announced that the U.S. Food and Drug Administration (FDA) has approved the PROMUS(TM) Everolimus-Eluting Coronary Stent System for the treatment of coronary artery disease. The PROMUS Stent is a private-labeled XIENCE(TM) V Everolimus-Eluting Coronary Stent System manufactured by Abbott and distributed by Boston Scientific under an agreement executed prior to the 2006 acquisition of the former Guidant Corporation by Boston Scientific. FDA approval clears the way for Boston Scientific to launch the PROMUS Stent immediately in the U.S.

The PROMUS Stent expands Boston Scientific's drug-eluting stent (DES) portfolio, which includes the TAXUS(R) Express2(R) Paclitaxel-Eluting Coronary Stent System (in the U.S. and international markets) and the TAXUS(R) Liberte(R) Paclitaxel-Eluting Coronary Stent System (in international markets), making Boston Scientific the only company to offer physicians the choice of two distinct drugs (paclitaxel and everolimus) on separate DES platforms.

"The PROMUS Stent has shown outstanding deliverability, low late loss and the potential to reduce the need for re-interventions," said Ted Feldman, M.D., F.S.C.A.I., Director of the Cardiac Catheterization Laboratory at Evanston Northwestern Healthcare in Evanston, Illinois. "These benefits will make the PROMUS Stent an attractive new treatment option for U.S. physicians and their patients."

"FDA approval of the PROMUS Stent fulfills Boston Scientific's promise of an unprecedented two-drug strategy - two distinct drugs on two highly deliverable stent platforms," said Jim Tobin, president and CEO of Boston Scientific. "The PROMUS Stent complements our broad DES portfolio and further reinforces Boston Scientific's leadership in the DES market, as well as our commitment to continued innovation and improved patient outcomes."

The next-generation PROMUS Stent is a highly deliverable stent made from cobalt chromium, which allows for thinner struts without sacrificing strength or visibility. The SPIRIT clinical trials indicate that the combination of the polymer/stent platform and the controlled release of the everolimus drug results in excellent deliverability, a strong safety profile, low levels of late loss and improved efficacy, making the PROMUS (XIENCE V) Stent a valuable addition to the U.S. drug-eluting stent market.

Boston Scientific's PROMUS Stent and Abbott's XIENCE V Stent are identical products sold by the respective companies under different brand names. The PROMUS (XIENCE V) Stent is indicated for improving coronary luminal diameter in patients with symptomatic heart disease due to de novo native coronary artery lesions (up to 28 mm long) with reference vessel diameter of 2.5 to 4.0 mm.

As a result of agreements related to its acquisition of Guidant in 2006, Boston Scientific shares the rights to everolimus-eluting stent technologies with Abbott, including the XIENCE V Everolimus-Eluting Coronary Stent System (marketed by Boston Scientific as the PROMUS Stent). The company will continue to market its internally developed paclitaxel-eluting TAXUS Stent Systems, which have been the worldwide DES market leaders, implanted in more than four million people. Boston Scientific is also developing paclitaxel- eluting, everolimus-eluting and bare-metal versions of its third-generation Element(TM) Stent, which uses a unique platinum-enriched alloy.

The PROMUS Stent is currently for sale in Europe and certain other international markets. TAXUS and PROMUS are trademarks of Boston Scientific Corporation or its affiliates. XIENCE is a trademark of the Abbott Laboratories group of companies. SPIRIT is sponsored by Abbott. The TAXUS Liberte Paclitaxel-Eluting Coronary Stent System is pending approval by the FDA and is not available for sale in the United States.

Boston Scientific is a worldwide developer, manufacturer and marketer of medical devices whose products are used in a broad range of interventional medical specialties.
