"Ventricular Assist Device With Distal Thrust Bearing" in Patent Application Approval Process (USPTO 20240277996).

Inventors from Israel have filed a patent application for a ventricular assist device that aims to assist and unload cardiac chambers in patients with failing hearts or those at risk during coronary interventions. The device includes a motion-cushioning spring and an elastomeric material to reduce the risk of thrombi and hemolysis. It also features a distal thrust bearing to prevent axial motion of the impeller in response to pressure variations. The device includes an axial shaft, an impeller, a frame, and a distal thrust bearing, as well as a motion-cushioning spring, an elastomeric material, a purging system, and a pump-outlet tube for blood flow.
