Zusammenfassung:A thrombectomy system is provided that, in various embodiments, a rotating impeller that may be translated within limits along a guidewire and within a catheter. The rotating impeller is, during operation, either located entirely inside or outside of the distal end of the catheter's lumen or at least partially outside of the distal end of the catheter's lumen. In some cases, the impeller may be prevented from rotating if at least partially inside the catheter's lumen. The rotating impeller may achieve a working diameter that is greater than its resting diameter.
