( Trial results report no new stent throm...)Taxus VI Clinical Trial Demonstrates Positive Long-Term Outcomes,for Moderate-Release Paclitaxel-Eluting Stent at Four Years,Health

NATICK, Mass., and BARCELONA, Spain, May 22, 2007 /PRNewswire-FirstCall/ -- Boston Scientific Corporation today announced four-year follow-up data from its TAXUS VI clinical trial. The data demonstrated that the safety and efficacy benefits associated with a moderate-release formulation of the TAXUS(R) Express(TM) paclitaxel-eluting stent system -- which is not approved for commercial distribution -- were maintained at four years with no new stent thrombosis reported after two years. Analysis of the data was presented by Professor Eberhard Grube, M.D., Heart Center Siegburg, Germany, the Co- Principal Investigator of the trial. The Company made the announcement at the annual Paris Course on Revascularization (EuroPCR) in Barcelona.

"Even though the moderate-release TAXUS formulation, with an 8-10 fold higher in vitro dose, was never commercialized, the excellent ongoing results in TAXUS VI further demonstrate the margin of safety of the commercial slow- release TAXUS stent now implanted in more than four million patients worldwide," said Paul LaViolette, Boston Scientific Chief Operating Officer. "With no stent thrombosis after two years, a low cardiac death rate, and a low TLR rate, we continue to be impressed with how paclitaxel performs in this high-risk patient population."

"The four-year results from TAXUS VI demonstrate that the safety and efficacy benefits associated with the moderate-release TAXUS paclitaxel- eluting stent system were maintained in patients with complex coronary artery disease at four years," said Professor Grube. "The performance of the TAXUS stent in these patients was extremely impressive when considering the complexity of their disease, including patients with long lesions, small vessels, and those requiring multiple, overlapping stents."
