1. A method comprising:
- coating a medical disposable device having an expandable structure with a polymer coating including a poly(hydroxyethyl methacrylic) acid complexed with iodine and a substantially water-insoluble therapeutic agent;
introducing the medical disposable device into a body lumen;
expanding the expandable structure of the medical disposable device to contact the polymer coating against the body lumen, thereby delivering the substantially water-insoluble therapeutic agent to the body lumen; and
contracting the expandable structure.

Abstract
A method and device for local delivery of a water-insoluble therapeutic agent 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 comprises poly(HEMA) 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.
