Catheter system for containing and removing vascular occlusions

Abstract

Abstract Intravascular catheters and a method for the treatment of a stenosis or an occlusion in a blood vessel. A main catheter (406) is first delivered to a site proximal to the occlusion (410). The main catheter (406) may include an occlusive device (408) at its distal end. An inner catheter or guidewire (420) having an occlusive device (422) at its distal end is delivered to the site of the occlusion (410), and the occlusive device (422) is activated at a site distal to the occlusion (410). A therapy catheter is then introduced to treat the occlusion (410). Next, an intermediate catheter (424) is delivered just proximal to the occlusive device (422), and the intermediate catheter (424) is used to aspirate the area removing particles and debris. Following the aspiration, the intermediate catheter (424) may be used to irrigate the area if desired. The aspiration and optional irrigation steps are preferably repeated until the particles and debris are removed. The catheter and method provide for minimally invasive devices and procedures which can be performed quickly and efficiently, with reduced risks to the patient.
