Abstract:
An arterial cannula with associated filter, comprising:a blood cannula having an outer surface, a distal end adapted to enter an artery, a proximal end adapted to receive blood or other fluids, and a lumen which extends longitudinally from the proximal to the distal end;an expandable filter disposed about the distal end of the blood cannula which is expandable between a contracted condition and an enlarged condition; andan occluder which is expandable between a contracted condition and an expanded condition, wherein the occluder is disposed at a circumferential position along the side of the blood cannula and, when in the contracted condition, is closely associated with the distal end of the blood cannula at a region proximal the filter, while the occluder expands upon activation to substantially occlude an artery upstream of the mesh.
