braided mesh of the cuff 10 and the cuff is ready to receive a prosthetic device such as a stented prosthetic valve 24 fig6 and 7 notably despite the irregular shape of the stenosed valve 18 the central lumen 16 of the cuff presents a path through the targeted site and provides an ideal receiving seat for the prosthetic valve 24 in fig6 the stented prosthetic valve 26 is percutaneously delivered to the cuff 10 via a catheter 28 the catheter 28 is inserted directly into the cuff lumen 16 using the funneled end 13 as a guide in fig7 the prosthetic valve 26 is expanded and the catheter 28 removed expanding the stented prosthetic 26 necessarily expands the central lumen 16 doing so causes the cuff 10 to shorten and the flared ends 12 and 13 to fold back further placing a more secure grip on the stenosed valve 18 furthermore any plaque or other material dislodged during the expansion of the prosthetic 26 is trapped by the ends 12 and 13 the cuff 10 provides an optimal seat for the prosthetic 26 and prevents any blood from leaking around the prosthetic valve 26 over time the braided strand s promote ingrowth further improving the seal provided by the cuff 10 one embodiment of the present invention uses a non.
