Abstract:
Embodiments of the invention include bioactive agent eluting devices. In an embodiment the invention includes a bioactive agent delivery device including a substrate, a hydrophilic polymer disposed on the substrate, and a substantially amorphous bioactive agent disposed on the surface of the hydrophilic polymer. In an embodiment, the invention includes a method of making a bioactive agent delivery device including depositing a hydrophilic polymer on a substrate forming a hydrophilic surface and depositing a substantially amorphous bioactive agent on the hydrophilic surface. In an embodiment, the invention includes a bioactive agent-eluting catheter including a catheter shaft and an expandable balloon disposed on the catheter shaft. Other embodiments are included herein.

Claim (Index 11):
A bioactive agent-eluting catheter comprising:\n a catheter shaft; an expandable balloon disposed on the catheter shaft; a hydrophilic polymer layer disposed on the outside surface of the balloon, wherein the hydrophilic polymer layer is covalently bonded to the balloon through the reaction product of a latent photoreactive group, the hydrophilic polymer layer comprising a polymer selected from the group consisting of poly(acrylamide), poly(methacrylamide), poly(vinylpyrrolidone), and vinyl pyrrolidone/(meth)acrylamide copolymers; a bioactive agent forming a layer disposed over the surface of the hydrophilic polymer layer, the bioactive agent comprising a hydrophobic bioactive agent; and wherein the bioactive agent releases from the device into an aqueous environment in under 30 seconds when exposed to an aqueous environment.
