Abstract
Heart valve prostheses have annular valve bodies with central passageways and valve members supported for pivotal and translational movement between open and closed positions. The occluders, which may be either of a bileaflet or single occluder design, are supported within the bodies by pairs of ears extending from opposite locations to interengage with corresponding arcuate depressions to guide the occluders between their closed positions where they seat against upstream protuberances of the valve bodies and their open position where they are positioned between the upstream protuberances and downstream protuberances.
