摘要:
The present invention relates generally to coated medical devices, preferably a stent, that has a drug-eluting surface completely or partially coated with a coating that comprises two or more forms of a biologically active material. In particular, the invention is directed to a coated medical device having a coating that comprises at least one polymer and a biologically active material that is present in at least two different forms. The coating may include more than one coating layer. Preferably, the coating is capable of releasing the different forms of the biologically active material in different amounts, at different rates, and/or at different time periods. The invention also relates to methods of making and methods of using the coated medical device.
