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 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 endoluminally delivering a valvular prosthesis within an anatomic passageway to replace an anatomic valve using a catheter comprised of at least one section near a distal end of the catheter, a first section consisting of the valvular prosthesis covered by a sheath, comprising the steps of:
-
passing the at least one section of the catheter through an anatomic passageway so that the first section is positioned distal the anatomic valve; positioning the first section within the anatomic valve for deployment of the valvular prosthesis; and withdrawing the sheath and the catheter to release the valvular prosthesis from the sheath onto the dilitated anatomic valve to functionally replace the anatomic valve. - View Dependent Claims (11, 12, 13, 14, 15)

16. 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; and Attaching the graft to at least portions of either or 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. - View Dependent Claims (17, 18, 19, 20)
