Abstract
A coated implantable medical deviceincludes a structureadapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layerposited on one surface of the structure; and at least one layerof a bioactive material posited on at least a portion of the coating layer, wherein the coating layerprovides for the controlled release of the bioactive material from the coating layer. In addition, at least one porous layercan be posited over the bioactive material layer, wherein the porous layer includes a polymer and provides for the controlled release of the bioactive material therethrough. Preferably, the structureis a coronary stent. The porous layerincludes a polymer applied preferably by vapor or plasma deposition and provides for a controlled release of the bioactive material. It is particularly 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 a monomer vapor.
