[Sales of Promus, Taxus, Cypher, and the total market are as reported by BSX, BSX, JNJ, and BSX, respectively; sales of Xience and Endeavor are my estimates derived from divisional sales figures provided by ABT and MDT, respectively, and approximate market-share figures furnished by BSX. (Note: MDT’s fiscal calendar is out of phase with the other three companies.) All sales in $million.]
