Abstract
Methods and apparatus are provided for removing emboli during an angioplasty, stenting or surgical procedure using a catheter having an occlusion element disposed on its distal end, a suction device, and an aspiration lumen communicating therebetween. The occlusion element is configured to be placed proximal of a stenosis and deployed to occlude antegrade flow, so that flow is reversed in the vessel when the suction device is selectively activated. The aspiration lumen is sized so that an interventional device, such as an angioplasty catheter, may be readily advanced therethrough to the site of a stenosis. The suction device may be activated intermittently at key stages of the procedure to provide reverse flow through the vessel, and the catheter may include bypass holes for limiting suction levels and/or providing intermittent antegrade flow.
