1. An endolumenally implantable prosthesis comprising:
- a. a tubular stent body member comprising a plurality of spaced struts with interstices between adjacent pairs of struts, the tubular stent body having lumenal and ablumenal surfaces, a central annular opening along a central longitudinal axis of the tubular stent body member, a proximal anchor section having a constant radius along the central longitudinal axis of the tubular stent body member, a distal anchor section and an intermediate annular section, wherein the proximal anchor section and the distal anchor section are diametrically greater than the intermediate annular section, wherein the proximal and distal anchor sections each further comprise a plurality of spaced struts with interstices between adjacent pairs of struts and each of the proximal and distal anchor sections radially expands relative to the intermediate annular section; and
b. a graft member covering at least a portion of at least one of the lumenal and ablumenal surfaces of the tubular stent body member and subtending the central annular opening of the tubular stent body member and forming a valve member.

14. A prosthesis endolumenally implantable in an anatomical passageway having a valve member comprising:
-
a. a tubular stent body member comprising a plurality of spaced struts with interstices intermediate adjacent pairs of struts, the tubular stent body having lumenal and ablumenal surfaces, a central annular opening along a central longitudinal axis of the tubular stent body member, a proximal anchor section, a distal anchor section, and an intermediate annular section, wherein a substantial portion of an ablumenal surface of at least one of the proximal anchor section and the distal anchor section contacts tissue adjacent a valve member, the proximal and distal anchor sections of the tubular stent body member each further comprise a flange that projects radially outward and away from the central longitudinal axis of the tubular stent body member and each of the flanges further comprises an oriented opening in each of the flanges; and b. a graft member covering at least a portion of at least one of the lumenal and ablumenal surfaces of the tubular stent body member and subtending the central annular opening of the tubular stent body member and forming the valve member, wherein the valve member is disposed in the central annular opening of the tubular stent body member to open and to close the central annular opening of the tubular stent body member. - View Dependent Claims (15, 16, 17, 18, 19, 20)
