Abstract: A grafted network including one or more graft segments for use in coronary bypass procedures and which are configured to operably transport bypass blood flow from a singular supply location to one or more delivery locations in the grafted network is provided in combination with one or more multiple channel blood flow connectors for directing such bypass blood flow in the grafted network to one or more vascular members requiring restorative blood flow thereto. The grafted network also preferably includes one or more devices for operably maintaining the grafted network under relatively high internal fluid pressure so as to continuously supply selective vascular members with adequate bypass blood flow.

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.
