Abstract
A medical device includes an inflatable balloon defining an interior surface and an exterior surface, and a coating including a therapeutic agent disposed on the exterior surface of the inflatable balloon. The coating has a release transition temperature within a range from about 25° C. to about 50° C. When the temperature of the coating is below the release transition temperature, the coating retains at least a portion of the therapeutic agent on the exterior of the inflatable balloon. When the temperature of the coating is above the release transition temperature, the coating releases at least a portion of the therapeutic agent from the exterior of the inflatable balloon.
