Abstract
A venous valve prosthetic implant for treatment of venous disease may include an expandable anchoring frame, a valve seat attached to the anchoring frame, a ball retention member attached to the anchoring frame, and a ball disposed within the lumen of the anchoring frame, between the valve seat and the ball retention member. The anchoring frame may include a first end, a second end, and a middle valve portion, where the middle valve portion expands to a smaller diameter than a diameter of either the first end or the second end. The ball may move back and forth within the middle valve portion, between a fully open position and a fully closed position.
