US Patent 12023479 Pulsatile ventricular assist device

A tubular pulsatile ventricular assist device (PVAD) system for providing forward flow of blood in a pulsatile, peristaltic, and non-hemolytic manner to help reduce the amount of blood clotting associated with current ventricular devices on the market. The system can encircle a portion of a blood vessel, and the system can sequentially apply a pressure through each port in a particular pre-determined patter so as to selectively occlude the lumen, thereby creating a pulsatile, peristaltic movement along a length of system. Said movement causes blood to flow through the portion of the blood vessel.
