"With nearly 70 percent sales growth, 200 percent earnings growth and 80 percent
gross margins, this quarter was one of the best performances in our history,"
said Jim Tobin, President and Chief Executive Officer of Boston Scientific. "The
quarter also saw the continued broad acceptance of our TAXUS coronary stent
system, which is proving itself to be the revolutionary technology we had hoped
it would become. We also made progress during the quarter on our next-generation
coronary stent system as well as several other promising projects in our
pipeline."
