An apparatus for collecting blood clots, plaque, and other debris in arteries or veins, said apparatus comprising: a filter assembly having a chamber with a paddle assembly and a porous floor disposed therein; and tubes for coupling said filter assembly to an artery and to a vein.

Method and apparatus for medical device for aspiration of thromboemobolic debris

A catheter apparatus captures thromboembolic material in the arterial and venous circulation. The apparatus includes an inner hollow tube and an outer hollow tube in sliding engagement with the inner hollow tube. A radially expandable segment, such as an inflatable balloon, is attached near the distal end of the catheter. One end portion of the balloon is attached to the inner tube and the other end portion is attached to the outer tube. When the catheter is advanced through a vessel to be treated, the balloon is deflated and the outer tube is slidably advanced to a storage position so that the balloon compactly surrounds the catheter. When the catheter is in place within the vessel, the outer tube is slidably advanced to a treatment position and the balloon is inflated. As the vessel is treated, the inflated balloon captures and contains thromboembolic particles that may be released, and the particles are suctioned out of the patient through apertures located in the outer hollow tube proximal to the balloon.

Apparatus for thromboembolic protection

An endovascular stent graft is provided for use in treating abdominal aortic aneurysms. The endovascular stent has a tapered section which allows it to accommodate markedly large aortas such as the abdominal aorta and still connects to standard modular aortic stent grafts. Methods of utilizing the stent to treat abdominal aortic aneurysms and distal iliac aneurysms are also provided.

Tapered endovascular stent graft and method of treating abdominal aortic aneurysms and distal iliac aneurysms

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.
