ABSTRACT:
An implantable heart valve including a suturing ring within which the body of the valve may be rotatably positioned following surgical implantation. The suturing ring is held to the valve body by binding means, such as an annular band or series of cord wraps. In one embodiment, the binding means may be heat-relaxed after the suturing ring has been bound to the valve body, thereby facilitating rotation of the valve body in the suturing ring. Slip ring means may be interposed between the suturing ring and the valve body to facilitate rotation. The slip ring means may be shaped to permit the binding means to hold the suturing ring tightly at its edges to the valve body to prevent the suturing ring from separating from the valve body at their mutually adjacent edges. The slip ring means may comprise a single ring or a pair of concentric slip rings having a mutual low-friction interface.
