ABSTRACT:
A prosthetic heart valve is comprised of a low profile valve body defining a central orifice, and an occluder is supported within the valve body to pivot about an eccentric axis which is established by occluder-retaining means in the form of opposed, concave pocket members formed in inwardly projecting planar portions on the inner wall of the valve body. Lateral extensions on the occluder are insertable into the concave pocket members for movement between extreme limits which are established at least in part by limit stop elements directly associated with the pocket members and a rib portion on each of the lateral extensions. The novel and improved arrangement of the occluder retaining means enables a maximum range of movement while minimizing blood stagnation problems as well as stress and wear upon the valve elements.
