Abstract
A bioprosthetic valve graft comprises a valve frame and valve flaps, the latter acting to open or close a valve aperture to directionally control fluid flow through the bioprosthesis. The bioprosthetic valve graft comprises a biomaterial suturelessly bonded to the valve frame, avoiding sutures and substantially reducing medical complications in implantations.
