Abstract:
A venous valve for directing antegrade blood flow in an autologous vein of the body that requires a venous valve, said venous valve comprising a tubular conduit means from which said venous valve is formed, said tubular conduit means having a tubular conduit inlet end, a tubular conduit outlet end, and a tubular conduit wall;a portion of the tubular conduit wall being attached to another portion of the tubular conduit wall substantially from the inlet to the outlet end of said tubular conduit means forming two tubular members, a first tubular member having a first tubular member wall, and a second tubular member having a second tubular member wall;a portion of said first tubular member wall being attached to a portion of said second tubular member wall to position a substantial portion of said first tubular member wall in approximation with a substantial portion of said second tubular member wall with an approximation attachment;an inlet end of said second tubular member having a closure attachment to prevent antegrade blood flow from entering said second tubular member and to prevent retrograde blood flow from passing through said second tubular means;a portion of said first tubular member wall being attached via a valve cusp attachment to a portion of said second tubular member wall at approximately the outlet end of said tubular conduit member to form at least a portion of a valve cusp, said valve cusp directing retrograde blood flow into an outlet end of said second tubular member and preventing substantial retrograde blood flow through said first tubular member;whereby said venous valve directs antegrade blood flow from said tubular conduit inlet end to said tubular conduit outlet end and prevents substantial retrograde blood flow from said tubular conduit outlet end to said tubular conduit inlet end.
