Abstract
An expandable sheath is provided for delivering a therapeutic drug in a body lumen which comprises an expandable membrane with a therapeutic drug incorporated therein. The expandable membrane is in a cylindrical configuration and mounted on the balloon portion of a catheter for intraluminal drug delivery into a patient's vascular system. The expandable membrane may also be mounted on an intravascular stent, both of which are implanted within the patient's vascular system. The therapeutic drug then diffuses into the vascular system at a controlled rate to match a specific clinical need.
