ABSTRACT:
A prosthetic heart valve of the type that includes an annular support ring and at least one valving member. The valving member includes a pair of rotational members and the annular support ring includes a pair of apertures that each support a releasable insert. The releasable inserts include axle members that have a predefined rotational contact surface and the rotational members include depressions having a predefined rotational support surface. The geometries of the rotational contact surface and rotational support surfaces are such that a substantial point contact of rotation exists when the two surfaces are rotationally engaged. The invention may be conversely practiced with the releasable inserts including a depression and the rotational members including axle members.
