Method for containing and removing occlusions in the carotid arteries |
摘要 |
A method for the treatment of a stenosis or an occlusion in a blood vessel is disclosed in which a main catheter is first delivered to a site proximal to the occlusion. The main catheter may include an occlusive device at its distal end. An inner catheter or elongate member (e.g., a guidewire) having an occlusive device at its distal end is delivered to the site of the occlusion, and the occlusive device is activated at a site distal to the occlusion. A therapy catheter is then introduced to treat the occlusion. Next, a catheter is delivered just proximal to the occlusive device, and this catheter is used to aspirate and/or irrigate the area removing particles and debris. The aspiration and irrigation steps are preferably repeated until the particles and debris are removed. Perfusion may be performed by using a perfusion-filter distal of the lesion to be treated or a hypotube which extends beyond the occlusive device attached to the guidewire. The present invention provides for a minimally invasive procedure which can be performed quickly and efficiently, with reduced risks to the patient.
