摘要:
A heart valve assembly (10) includes an annular prosthesis (14) and a valveprosthesis (14). The annular prosthesis includes an annular ring (18) fordilating tissue within a biological annulus and a conformable sewing cuff (20)extending radially from the annular member. The valve prosthesis includes aframe (32) and a valve component. The annular ring is introduced into thebiological annulus to dilate tissue surrounding the biological annulus and thesewing cuff conforms to tissue above the biological annulus. Fasteners aredirected through the sewing cuff to secure the annular prosthesis to thebiological annulus. The annular prosthesis may include a baleen element forbiasing fabric on the annular ring outwardly to enhance sealing against thebiological annulus. A valve prosthesis is then advanced into the sinus cavity,and secured relative to the annular prosthesis. The sewing cuff may enhance aseal between the valve prosthesis and annular prosthesis.
