BIORESORBABLE STENT WITH EXTENDED IN VIVO RELEASE OF ANTI-RESTENOTIC AGENT

摘要

A method for decreasing the level of restenosis following a stent placement medical intervention involves the continuous administration of a dose of an anti- restenotic agent, such as paclitaxel, from the stent to vascular tissue in need of treatment in a controlled and extended drug release profile for a period of at least 60 days in vivo. The in vivo release profile is determined by in vivo animal experiments involving implanting a series of stents in animals, explanting the stents from the animals at selected time points, and extracting remaining drug from the explanted stents.
