Personalized aortic valve prosthesis
First Claim
1. A personalized prosthetic valve for implantation at native valve treatment site, said personalized prosthetic valve comprising:
- a self-expanding mesh having a collapsed configuration and an expanded configuration, the collapsed configuration adapted to be delivered to the native valve treatment site, and the expanded configuration adapted to expand the valve into engagement with the treatment site, wherein the mesh in the expanded configuration is personalized prior to implantation to match the treatment site, wherein the mesh has an outer surface prior to implantation that substantially matches the native valve treatment site shape and size in the expanded configuration, and wherein the self-expanding mesh forms a central lumen configured to allow blood or other body fluids to pass therethrough, andwherein the valve further comprises a plurality of valve leaflets coupled to the self-expanding mesh and having an open configuration and a closed configuration,wherein in the open configuration the blood or the other body fluids are free to pass through the valve, andwherein in the closed configuration the plurality of leaflets are closer toward one another than in the open configuration, and the blood or the other body fluids are prevented from flowing upstream through the prosthetic valve.

Abstract
A personalized prosthetic valve for implantation at a native valve treatment site includes a self-expanding mesh and a plurality of valve leaflets coupled to the mesh. The mesh may be delivered to the native valve in a collapsed configuration, and in an expanded configuration the mesh engages the native valve. The mesh in the expanded configuration is also personalized to match the treatment site, such that the outer mesh surface substantially matches the treatment site shape and size. The self-expanding mesh forms a central lumen configured to allow blood or other body fluids to pass therethrough. In the open configuration, blood passes through the prosthetic valve, and in the closed configuration, the plurality of leaflets are closer together and blood is prevented from flowing upstream through the prosthetic valve.
