Venous valve apparatus, system, and method
First Claim
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, andwherein the first valley and the second valley are positioned opposite one another and are perpendicular to the common axis, andwherein, 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, andwherein 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.

Abstract
A venous valve with a tubular frame that includes an outer surface and an inner surface opposite the outer surface and defining a lumen, and a cover over at least the outer surface of the tubular frame, where the cover includes surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the lumen. A system with the venous valve and a catheter including a proximal end and a distal end, the venous valve located between the proximal end and distal end of the catheter. A method including forming the venous valve and reversibly joining the venous valve and a catheter. A method including positioning at least part of the catheter including the venous valve at a predetermined location and deploying the venous valve from the catheter at the predetermined location.
