Abstract
A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the tissue of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with a non-durable coating which is complexed with iodine and has a substantially water-insoluble therapeutic agent dispersed therein. The medical disposable device is inserted into a body lumen, and expanded to contact the non-durable coating against the body lumen and deliver the substantially water-insoluble therapeutic agent to the body lumen tissue.
