Abstract:
1. A venous valve prosthesis comprising: opposing pliable nonbiological leaflet members configured to selectively shift between a first normally open position whereby fluid may flow in a first direction through an axial passageway defined between the leaflet members and a second closed position whereby fluid is prevented from backflowing through the axial passageway in a second direction opposite the first direction, the leaflets being normally open and only closing upon reversal of fluid flow to the second direction; and, an elongated hollow support member cooperably receiving the leaflet members, the support member including opposed cutaway regions defining a pair of struts extending axially of the support member for supporting the leaflet members, the cutaway regions in cooperation with said struts configured for allowing the leaflet members to selectively collapse inwardly toward the second closed position.
