    摘要: A coated implantable medical device 10 includes a structure 12 adapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layer 16 posited on one surface of the structure; and at least one layer 18 of a bioactive material posited on at least a portion of the coating layer 16, wherein the coating layer 16 provides for the controlled release of the bioactive material from the coating layer. In addition, at least one porous layer 20 can be posited over the bioactive material layer 18, wherein the porous layer includes a polymer and provides for the controlled release of the bioactive material therethrough. Preferably, the structure 12 is a coronary stent. The porous layer 20 includes 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.

    摘要: A variable curvature stent limb is disclosed herein. A stent derived from a plurality of these variable curvature stent limbs may be highly compressible, such that it is compatible with a low-profile delivery device. This stent may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.

    摘要: A self-expanding or otherwise expandable artificial valve prostheses for deployment within a body passageway, such as a vessel or duct of a patient. The valve prostheses include a support structure having an outer frame, a supporting member and a valve leaflet. The portion of the valve leaflet is supported by the supporting member and is positioned away from the wall of the body passageway when the device is deployed within the body passageway.
