Abstract
A coated implantable medical deviceincludes a structureadapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract, and at least one layerof an immunosuppressive agent posited over at least one surface of the structure. Optionally, the devicecan include at least one porous, preferably polymeric layerposited over the layerof immunosuppressive agent, and can alternatively or additionally include at least one coating layerposited on one surface of the structure, the at least one layerof immunosuppessive agent being posited in turn on at least a portion of the coating layer. The porous layerand the coating layereach provide for the controlled release of the bioactive material from the device. The structureis preferably configured as a coronary stent. The polymer of the porous layeris preferably applied by vapor or plasma deposition. It is particularly preferred that the polymer is a polyamide, parylene or a parylene derivative which is deposited without solvents, heat or catalysts, but rather by condensation of a monomer vapor.
