Abstract

This invention relates to prosthetic cardiac and venous valves and a single catheter device and minimally invasive techniques for percutaneous and transluminal valvuloplasty and prosthetic valve implantation.

Claims

1. An endolumenally implantable prosthesis 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 in 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.

2. An endolumenally implantable prosthesis as defined in claim 1 wherein 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.

3. An endolumenally implantable prosthesis as defined in claim 2 wherein each of the flanges further comprises an oriented opening in each of the flanges.

4. An endolumenally implantable prosthesis as defined in claim 1 wherein the proximal and distal anchor sections of the tubular stent body member each further comprise a flange that projects substantially perpendicular to the central axis of the tubular stent body member.

5. An endolumenally implantable prosthesis as defined in claim 4 wherein each of the flanges further comprises an oriented opening in each of the flanges.

6. An endolumenally implantable prosthesis as defined in claim 1 further comprising a membrane disposed in the central annular opening of the tubular stent body member to occlude the central annular opening of the tubular stent body member.

7. An endolumenally implantable prosthesis as defined in claim 1 further comprising a valve 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.
