Abstract
A thromboembolic capturing system captures thromboemboli in the arterial and venous circulation. A vascular tube such as a guidewire includes a porous filter at is distal end. The filter is collapsible, capable of maintaining open and closed configurations when placed within a vessel. Opening and closing of the filter is controlled by strings or sutures running through the tube. The filter is able to retain captured thromboembolic material in conjunction with angioplasty or interventional cardiovascular procedure. When the tube comprises a guidewire, it is of sufficient strength, torquability and softness to be used for angioplasty, stent placement and other interventional procedures.
