CARDIAC VALVE PROSTHESIS

摘要

Provided herein is a prosthetic device in patients with ventricular assist device (VAD) support and a closed off aortic valve orifice, which reestablishes the formation of normal fluid flow patterns in the aortic root. The prosthesis includes a circular body having a first surface and a second surface and a projection disposed on the first surface of the body, wherein the projection includes a plurality of walls extending away from the first surface of the body, each wall being positioned such that a first side edge contacts a center of the body, thereby forming a plurality of intercepted arcs, each located between adjacent walls; and a plurality of concave parabolic surfaces, each disposed within an intercepted arc. Also provided are methods of using the prosthetic device to reduce thrombosis formation in patients with VAD support.

主权项

1. A cardiac prosthesis comprising:
(a) a circular body having a first surface and a second surface; (b) a projection disposed on the first surface of the body, the projection comprising:
(i) a plurality of walls extending away from the first surface of the body, each wall being positioned such that a first side edge contacts a center of the body, thereby forming a plurality of intercepted arcs, each located between adjacent walls; and(ii) a plurality of concave parabolic surfaces, each disposed within an intercepted arc, wherein the projection is substantially shaped as a closed cardiac valve.
