摘要:A coated implantable medical device includes a structure adapted for
introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary
tract; at least one coating layer posited on one surface of the structure; and at least onelayer of a bioactive material posited on at least a portion of the coating layer , whereinthe coating layer provides for the controlled release of the bioactive material from thecoating layer. In addition, at least one porous layer can be posited over the bioactivematerial layer , wherein the porous layer includes a polymer and provides for thecontrolled release of the bioactive material therethrough. Preferably, the structure is acoronary stent. The porous layer includes a polymer applied preferably by vapor orplasma deposition and provides for a controlled release of the bioactive material. It isparticularly preferred that the polymer is a polyamide, parylene or a parylene derivative,which is deposited without solvents, heat or catalysts, and merely by condensation of amonomer vapor.
