    摘要： A silver 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 layer 18 of a bioactive material posited on one surface of structure 12; and at least one porous layer 20 posited over the bioactive material layer 18 posited on one surface of structure 12 and the bioactive-material-free surface. Also included is a layer or impregnation of silver 45. Preferably, the structure 12 is a coronary stent. The porous layer 20 is comprised of 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, merely by condensation of a monomer vapor. Silver is included as a base material, coating or included in a carrier, drug, medicament material utilized with the implantable stent.

    摘要： A stone retrieval basket having superelastic metallic alloy wires attached to the distal end of an inner elongaged member tube for retrieving calculi and crushing them against an outer introducer tube percutaneously inserted into a patient. The basket comprises kink-resistant superelastic metallic alloy wires such as nitinol forming a bulbous shape for capturing calculi therein. The ends of the superelastic wires of the basket are attached to the distal end of a inner elongated member tube with the aid of sleeves crimped thereon, which are soldered or spot welded in recesses about the distal end of the inner tube. The outer tube is percutaneously inserted into the biliary or urinary system in which the basket is then inserted to capture large-sized stones. A peel-away sheath is also included to introduce the basket and inner elongatged member tube into the outer introducer tube. A dilator member, which is extendable through the passageway of the inner tube, removes any residual debris from the tube that may be left during the stone removal procedure.

    摘要： A skylight structure offering superior water intrusion resistance has a glass plate superposed in spaced relationship above a plastic dome member having an integral inverted U-shaped flange. A cap marginally framing the glass and plastic members has spaced downwardly depending flanges with an inner shorter flange abutting the outer surfaces of the plastic flange and an outer longer flange spaced from and shielding the outer surfaces of the plastic flange. The outside lower end of the U-shaped flange is cured outwardly.

    摘要： A medical retrieval basket having superelastic metallic alloy wires attached to the distal end of an inner elongated member tube for percutaneously capturing and removing calculi from a cavity or duct of a patient. The basket comprises kink-resistant superelastic metallic alloy wires such as nitinol which forms a bulbous shape for capturing calculi therein. The ends of the superelastic wires of the basket extend through the passageway of the inner elongated member tube and are attached to the proximal end of the tube. An outer elongated member tube is percutaneously inserted into the biliary or urinary system. The inner member tube is inserted through the outer member tube into a duct, cavity or organ of the patient. The distal ends of both the inner and outer member tubes have a predetermined longitudinal curvature for controlling the positioning of the basket and the tubes within the patient. A sleeve is provided at the proximal end of the inner member tube for limiting the insertion thereof in the outer member tube.
