Abstract:
1. A venous valve, comprising: a radially collapsible and expandable tubular frame with an open frame configuration, wherein the tubular frame includes an outer surface and an inner surface opposite the outer surface and defining a lumen, only one band of wishbone-shaped frame members, the band of wishbone-shaped frame members formed about a first end of the frame, and a first vertex and a second vertex relative the first end of the tubular frame, a first valley and a second valley extending from the first vertex and the second vertex to the first end of the tubular frame, wherein the first vertex and the second vertex are positioned opposite one another along a common axis, and wherein the first valley and the second valley are positioned opposite one another and are perpendicular to the common axis, and wherein, a first strut of the tubular frame passes immediately from the first vertex to the first valley and a second strut of the tubular frame passes immediately from the first valley to the second vertex to form a tapering point, and wherein each of the first strut and the second strut comprise a half-wishbone shape; and a radially collapsible and expandable tubular cover positioned around the entire outer surface of the tubular frame, wherein the tubular cover is connected to the first vertex and to the second vertex to form a first valve leaflet across the first valley and a second valve leaflet across the second valley between the first vertex and the second vertex to oppose flow of a liquid through the lumen from the second end to the first end.
