Abstract
A synthetic venous valve and graft combination that exerts no radial force at the valve site is disclosed. The trilobed valve (11) is passively actuated by venous blood pressure changes. When open, the aperture for blood flow is approximately that of the original vein. The prosthesis is useful for replacing nonfunctioning venous valves in the human vasculature.
