Abstract: 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.

Abstract: A vascular catheter including a radially expandable segment, such as an inflatable balloon, and an expanded distal tip having an increased storage volume is disclosed. The inflatable balloon segment of the catheter may be used to provide traditional balloon angioplasty to a portion of a blood vessel narrowed by stenosis, and the expanded distal tip of the catheter apparatus may be used to safely capture, store, and remove a thromboembolic protection device such as an embolic filter used to catch pieces of plaque and other embolic material dislodged during the balloon angioplasty procedure. The catheter of the present invention provides an effective means for dilating a narrowed portion of a blood vessel, as well as preventing the need for deploying a second catheter system to capture and retrieve the embolic filter. The present invention also greatly reduces the chance for plaque and other thromboembolic material to escape from the embolic filter and enter the patient's bloodstream.

Abstract: The present invention relates to an improved endovascular stent and stent graft, which may be combined to form a stent system. The stent system may be used to treat aneurysms, such as abdominal aortic aneurysms. The stent system includes at least one port located in the sidewalls of the stent and/or stent graft to allow for the delivery of embolic devices to locations outside of the stent system. Methods of utilizing the stent system for embolizing an aneurysm are also provided.
