Abstract

A supported bioprosthetic heart valve is pro-vided. The valve includes a stent (16) and a biological valve member (18). The stent has an annular frame de-fined by a support rail. The support rail (36) is formed to define a triad of axially-projecting circumferentially-spaced commissure posts (38, 40, 42), each post hav-ing an inverted U-shaped configurationn and a pair of legs. Each of the pair of legs has an upper end and a lower end. The lower end of each leg merges smoothly with the lower end of a leg of an adjacent commis-sure post. A sleeve (48) having an inflow end (50) and an outflow end is fitted around the annular frame.
The biological valve member is defined by a tubular wall (20) and three leaflets, the three leaflets being attached to the tubular wall and axially converging along three commissures. The biological valve mem-ber has a shape which fits the contour of the support rail and is disposed under the support rail. The bio-logical valve member is sutured to the support rail and the outflow end of the sleeve. The bioprosthetic valve member also includes a suturing cuff (46) which is not rigidly attached to the support rail allowing the valve to expand and contract in the lateral direction. The suturing cuff is formed by wrapping the inflow end of the sleeve around a ring-shaped cushion and suturing the sleeve to itself encapsulating thus the ring-shaped cushion. An inflow support ring (47) may also be pro-vided within the suturing cuff for added lateral support.
