Abstract
Balloon catheters are prepared to include a coating of body affecting chemicals on the exterior of the balloon. The coating releases from the balloon when the balloon is inflated into contact with the lumen to be treated. The device provides accurate placement of the dosage required at the location in need of treatment. The coating preferably includes drugs in microcapsules or microspheres. The catheters are especially useful in balloon angioplasty procedures.
