Biological passageway occlusion removal

Abstract

Abstract A device for the removal of a blockage in a passageway such as a dialysis graft (10) or in a body passageway includes a catheter for reception, aspiration of the blockage, and an occlusion engaging element (24) distal of the distal end of the catheter (16) which occlusion engaging element is supported on a wire (22) that extends through the catheter (16). At the distal end of the catheter (16), there is a device such as a multi-wing malecot expansion device (18) that is expanded after the catheter (16) is placed in position so as to block the occlusion from passing around the outside of the catheter (16). The support wire (22) can be a movable core guide wire (22) which has braided device (24) on its distal end.
