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 method for suturelessly attaching a biomaterial suturelessly bonded to the A method for securing a biomaterial to a valve frame includes positioning a flexible valve frame defining an open area on a first major surface of a biomaterial sheet having a peripheral edge, wherein positioning serves to approximate the valve frame and the peripheral edge of the biomaterial sheet to form an at least first bonding locus; and suturelessly bonding the biomaterial to the valve frame at the at least first bonding locus. The method avoids the disadvantages associated with conventional sutures and substantially reduces medical complications in implantations.
