Abstract
A heart valve prosthesis coated in its entirety with pyrolytic carbon. In a preferred embodiment, the prosthesis is formed of a base having a blood passageway and dual leaflets pivotally secured to the base to regulate the flow of blood through the passageway. The pivot connection between the base and leaflets is formed by recesses in the base and projections on the leaflets, the recesses and projection termini being formed as surfaces of revolution. The valve is assembled by elastically deforming the base to allow insertion of the projections within the recesses.
