COATED MEDICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a coated intra-vascular medical device having a structure adapted for introduction into a passage or vessel of a patient.

SOLUTION: The structure 12 is formed of preferably a non-porous base material 14 having a bioactive material layer. The medical device 10 is an implantable stent or balloon 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 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. The balloon further includes hydrophilic material positioned between the base material layer 14 and the bioactive material layer.
