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.
