<p>A bioprosthetic valve graft (1) comprises a valve frame (10) and valve flaps (12), the latter acting to open or close a valve aperture (14) to directionally control fluid flow through the bioprosthesis (1). The bioprosthetic valve graft (1) comprises a biomaterial suturelessly bonded to the valve frame (10), avoiding sutures and substantially reducing medical complications in implantations.</p> |
