Zusammenfassung:	Catheter devices for delivering therapeutic agent and methods of making the same. A method comprises applying, when the balloon is unexpanded and folded, a first coating to a first surface area of the balloon that is substantially exposed when the balloon is unexpanded and folded, the first coating being a coating to which the therapeutic agent coating material is substantially non-adherent; applying a therapeutic agent coating material to the balloon such that the therapeutic agent coating material adheres to a second surface area not coated with the first coating. Upon completion of the coating method, the therapeutic agent coating is substantially disposed within one or more folds of the balloon. A catheter device comprises therapeutic agent coating that is substantially covered when the balloon is unexpanded and folded. Expanding the balloon opens the one or more folds and substantially exposes the therapeutic agent.
