A method for delivering medication into an arterial wall for prevention of restenosis

摘要

A device (10) for preventing a restenosis within a vessel wall which permitsa medicament to be delivered at predetermined locations into the vessel wall and to be subsequently dispersed in a predetermined pattern. The device comprises a catheter with an expanding member (15) which is advanced into the vasculature of a patient until the expanding member is located as desired. The expanding member (15) is then expanded to force dispensers (20) into the vessel wall to the proper depth. A medicament is then pumped through the dispensers to create a plurality of equally spaced, localized medicinal deliveries which subsequently disperse to medicate an annulus shaped volume within the vessel wall.
