Abstract

Dynamic aspiration, such as in aspiration thrombectomy, provides a changing negative pressure in a catheter such that a dynamic suction force is exerted on a thrombus or occluding element. Various dynamic aspiration profiles may be used. Devices for providing dynamic aspiration may be used with existing catheter-pump systems which currently deliver only static aspiration. A dynamic suction force exerted on a thrombus may induce material fatigue and thereby reduce the clot's load-to-failure and time-to-failure as compared to existing suction thrombectomy techniques.
