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.

Venous valve prosthesis

A valve prosthetic implant for treating a vein or other blood vessel includes a tubular, expandable anchoring frame extending from a proximal end to a distal end of the implant, a valve seat formed at or near the middle of the anchoring frame, an expandable ball disposed within the lumen of the anchoring frame, and a ball retention tether attached to the expandable ball and to the valve seat and/or the anchoring frame. The anchoring frame may include a cylindrical proximal portion at the proximal end, a cylindrical distal portion at the distal end, an inwardly angled inlet portion between the cylindrical proximal portion and a middle of the anchoring frame, and an inwardly angled outlet portion between the cylindrical distal portion and the middle of the anchoring frame.
