A vascular catheter includes a strainer device at its distal end. The strainer device is collapsible, capable of assuming both an open configuration where it is able to capture emboli when emplaced in a blood vessel, and a closed configuration where it is able to retain any captured emboli within its confines. The catheter of the present invention is normally utilized in conjunction with conventional angioplastic treatment techniques. By locating the strainer device downstream from the site of the angioplastic treatment, any emboli which are released during such treatment may be captured and removed from circulation.
