Abstract

Artificial valves for use as a venous valve or a heart valve are disclosed. The valve includes a frame including a platform and a valve material coupled to the frame. The valve material is a plurality of filaments or a flap. The valve material is coupled to the frame such that in response to a force in a first direction, e.g. blood flow, the valve material extends in the direct of the force to allow blood to flow past the valve material. In absence of the force in the first direction, the valve material rests against the platform to block blood flow in a direction opposite the first direction.
