    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, and at least one layer 18 of an immunosuppressive agent posited over at least one surface of the structure 12. Optionally, the device 10 can include at least one porous, preferably polymeric layer 20 posited over the layer 18 of immunosuppressive agent, and can alternatively or additionally include at least one coating layer 16 posited on one surface of the structure 12, the at least one layer 18 of immunosuppressive agent being posited in turn on at least a portion of the coating layer 16. The porous layer 20 and the coating layer 16 each provide for the controlled release of the bioactive material from the device 10. The structure 12 is preferably configured as a coronary stent. The polymer of the porous layer 20 is 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.

    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 papillotome (10) including a multi-lumen inner member tube (11) with an outer member tube (16) positioned around the proximal portion thereof with a spacing therebetween for limiting the radial expansion of the inner member tube so that the elastic limit of the inner member tube is not exceeded. The material of and the spacing between the inner and outer member tubes is selected so as to longitudinally distribute the radial expansion of the inner member tube from a fixed or partial attachment of the inner and outer member tubes.
