Abstract
The present invention provides a mechanism by which the physical properties of diseased blood vessel walls can be manipulated to achieve an effective vessel lumen diameter for a prolonged period of time. The methods and devices of the present invention selectively isolate and treat the medial or adventitial layers of these diseased blood vessels. The invention is based on the delivery of proteolytic enzymes and crosslinking agents via specialized delivery devices to a select layer of the diseased blood vessel wall. By isolating and treating these layers of the artery, collagen degrading and collagen crosslinking agents can be delivered so as to affect the diameter of the blood vessels and control blood flow therein.
