Prosthetic Venous Valve Devices and Associated Methods

Abstract

A prosthetic venous valve device is disclosed and described, having a valve base including a cylindrical shape with a lumen configured for axial blood flow, the valve base further including an anterograde end and a retrograde end, a pair of flexure pivots coupled to opposite sides of the valve base at the anterograde end, and a pair of leaflets opposingly positioned with respect to one another and each pivotally coupled to one of the pair of flexure pivots, the pair of leaflets being separated from one another in a default open position, wherein the pair of leaflets are structurally configured to pivot from the default open position toward one another to close the prosthetic venous valve to limit retrograde venous blood flow under normal physiologic venous conditions.

What is claimed: 
     
         1 . A prosthetic venous valve, comprising:
 a valve base having a cylindrical shape with a lumen configured for axial blood flow, the valve base further including an anterograde end and a retrograde end;   a pair of flexure pivots coupled to opposite sides of the valve base at the anterograde end; and   a pair of leaflets opposingly positioned with respect to one another and each pivotally coupled to one of the pair of flexure pivots, the pair of leaflets being separated from one another in a default open position,   wherein the pair of leaflets are structurally configured to pivot from the default open position toward one another to close the prosthetic venous valve to limit retrograde venous blood flow under normal physiologic venous conditions.
