Intravascular aspiration system

Abstract

Abstract Catheters and method for the treatment of stenosis or an occlusion (56) in a blood vessel (5) in which an occlusive device (52) is first delivered and the occlusive device (52) activated at a site distal to the occlusion (56) to at least partially occlude the vessel (5) and create a working space surrounding the occlusion (56). A therapy catheter is then introduced to treat the occlusion (56) and a debris removal device (60) is delivered to aspirate debris (58) from the vessel (5). The need for a separate irrigation catheter and irrigation fluid is eliminated, which allows the procedure to be performed quickly and efficiently. The catheters and method are especially useful in the removal of occlusion from saphenous vein grafts, the coronary and carotid arteries, arteries above the aortic arch and vessels of similar size and pressure.
