Abstract
Devices described herein include a stentriever for removing an occlusive clot. The stentriever can include a membrane cover on the proximal end which can be sized to form a seal with the tip of an intermediate catheter. Clot engagement sections and/or a distal engagement section of the stentriever can also include a full or partial membrane covering to control the direction of aspiration and/or areas where the aspiration applies suction to the thrombus or clot. The membranes can be used to direct the aspiration so as to pull the clot deeper into the clot engagement sections of the stentriever, thereby improving grip on the clot. The design can also increase the effectiveness of clot fragment protection for friable clots by providing pores and/or clot cells in a distal engagement section.
