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 non-porous 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.

A balloon catheter medical device that releases a drug by immediate release for the selective therapy of specific diseased tissue or an organ part to which said drug will bind, comprising such a drug which is lipophilic, water-insoluble and immediately releasable, adhered to a smooth surface of the balloon of said catheter that comes into contact with the diseased tissue or organ part, which adhered drug when pressed against said tissue or organ part at least for a short time, is immediately released into said tissue or organ part, wherein the concentration of said drug on said surface is up to 20 μg/mm2.
A balloon catheter having folds in its balloon, comprising a lipophilic, water-insoluble drug which binds to tissue, said drug being adhered to a smooth balloon surface in a fashion wherein it is immediately released upon coming into contact with said tissue, wherein a balloon area covered with folds is coated with said drug which has been dried after application, and wherein the concentration of said drug on said surface is up to 20 μg/mm2.
A balloon catheter medical device that releases a drug by immediate release for the selective therapy of specific diseased tissue or an organ part to which said drug will bind, comprising such a drug which is lipophilic, water-insoluble and immediately releasable, adhered to a surface of the balloon of said catheter that comes into contact with the diseased tissue or organ part, which adhered drug when pressed against said tissue or organ part at least for a short time, is immediately released into said tissue or organ part, wherein the drug is adhered to said surface in a manner resulting in an amount of drug retained on said device of about 10% or less after a time period in which said balloon surface is in contact with said tissue of up to a few minutes, and wherein the concentration of said drug on said surface is up to 20 μg/mm2.
