Abstract

A method of creating a polymer coating on a medical device by powder coating the medical device with a powder material comprising a polymer and applying a solvent onto the powder coating to coalesce the powder coating into a continuous polymer film. A therapeutic agent may be mixed into the powder material, mixed into the coalescing solvent, or incorporated into the resulting polymer film. Also provided is a medical device having a polymer coating wherein the polymer coating is created according to the methods of the present invention.
