摘要: A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a nonporous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

摘要: A medical device (10) includes a structure (12) adapted for introduction into a patient, the structure (12) being formed of a preferably non-porous base material (14) having a roughened or textured surface (16). The structure (12) is conveniently configured as a vascular stent with a base material (14) of stainless steel, nitinol or another suitable material. The medical device (10) also includes a layer (18) of a bioactive material posited directly upon the roughened or textured surface (16) of the base material (14) of the structure (12). The surface (16) of the base material (14) is roughened or textured by etching or by abrasion with sodium bicarbonate or another suitable grit. A preferred roughened or textured surface (16) is thought to have a mean surface roughness of about 10 νin. (about 250 nm) and a surface roughness range between about 1/νin. and about 100 νin. (about 25 nm and about 2.5 νm). The particularly preferred use of sodium bicarbonate as the abrasive to provide roughness or texture to the surface (16) of the base material (14) of the structure (12) is additionally advantageous in the low toxicity of the sodium bicarbonate to production workers, the ease of product and waste cleanup, and the biocompatibility of any residual sodium bicarbonate.

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 of a bioactive material posited on at least a portion of the coating layer, 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 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: Endovascular filter (10) including a plurality of struts (14) with distal ends (18) adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (20), the filter being adapted to be retrieved if 5 desired. Strut distal ends (18) are coated with an antiproliferative agent (40) that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end (22) of the filter may also be so coated, or the entire filter.
