1. An implantable valvular prosthesis, comprising:
- a. a stent body member having luminal and abluminal surfaces thereof and a central opening along a central longitudinal axis of the stent body member;
b. a graft member comprising an outer graft member coupled to the abluminal surface of the stent body member and an inner graft member coupled to the luminal surface of the stent body member, wherein a terminal portion of the inner graft member is everted inwardly toward the central longitudinal axis of the stent body member;
c. at least one biasing arm coupled to and projecting from the stent body member and into the central opening of the stent body member;
d. at least one valve flap member formed by the terminal portion of the inner graft member coupled to the at least one biasing arm, the at least one valve flap member assuming a position, under zero pressure differential across the prosthesis, which occludes the central opening of the stent body member.

10. A method of manufacturing an implantable valvular prosthesis, comprising the steps of:
-
Fashioning a generally tubular stent body member, having a luminal and an abluminal surface and a central opening along a central longitudinal axis; Fashioning a graft; Attaching the graft to at least portions of both the luminal and abluminal surfaces of the stent body member, wherein the attachment of the graft to the stent body member forms at least one valve flap by everting a terminal portion of the graft inwardly toward the central longitudinal axis of the stent body member; and Wherein the step of fashioning the generally tubular stent body member further comprises shaping the stent body member to include at least one valve arm or blood flow regulator strut coupled to and projecting from the stent body member. - View Dependent Claims (11, 12, 13)
