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.
