摘要:
A stent having a polymeric coating for controllably releasing an included active agent. The polymeric coating includes a blend of a first polymeric material, which if alone, would release the agent at a first, higher rate, and a second polymeric material, which if alone would release the agent at a second, lower rate over a longer time period. One stent coating utilizes a faster releasing hydrophilic polymeric material and a slower releasing hydrophobic material. One stent coating includes a blend of a faster releasing PLA-PEO copolymer and a slower releasing PLA-PCL copolymer. One active agent is Taxol. One use of the Taxol delivering stent is to inhibit restenosis following angioplasty.
