  • Patent number: 11931055
    Abstract: An actuated telescoping system for navigation within a vascular lumen and thrombectomy of a thrombus. The system includes a tubular catheter member having an open distal end defining a catheter lumen, a vacuum source, a rotational drive system, a flexible shaft having a channel coupled to the rotational drive system for rotational movement in response thereto, and an optional guidewire selectively inserted at least partially within the flexible shaft. The flexible shaft is at least partially disposed within the tubular catheter member configured for uncoupled rotational and translational motion therein and to optionally define a corkscrew motion in response to rotational driving force by the drive system that results in formation of hydrodynamic vortices within the catheter lumen.
    Type: Grant
    Filed: December 2, 2021
    Date of Patent: March 19, 2024
    Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGAN
