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 implantable septal occluder prosthesis for treating a septal defect, comprising:

a stent body member having luminal and abluminal surfaces thereof and a central annular opening along a central longitudinal axis of the stent body member;

a graft member covering at least a portion of at least one of the luminal and abluminal surfaces of the stent body member;

a proximal flange and distal flange, wherein both the proximal flange and distal flange define opposing ends of the stent body member and project radially outward and away from the central longitudinal axis of the stent body member; and

an occluding membrane for occluding the septal defect, the occluding membrane coupled to the stent body and completely occluding the central annular opening such that fluid does not pass through the occluding membrane.

2. The implantable septal occluder prosthesis according to claim 1, wherein the proximal flange and the distal flange are defined by a plurality of stent struts and interstices.

3. The implantable septal occluder prosthesis according to claim 1, wherein the graft member further comprises an inner graft member coupled to the luminal surface of the stent body member.

4. The implantable septal occluder prosthesis according to claim 3, wherein the occluding member is coupled to the inner graft member.

5. The implantable septal occluder prosthesis according to claim 3, wherein the graft member further comprises an outer graft member coupled to the abluminal surface of the stent body member.

6. The implantable septal occluder prosthesis according to claim 1, wherein the proximal flange and the distal flange project substantially perpendicular to the central longitudinal axis of the stent body member.

7. A cardiac septal occluder prosthesis for treating a septal defect, comprising:

a. a structural support member comprising a plurality of strut members having interstices between adjacent strut members, the strut members and interstices defining a luminal surface, an abluminal surface and a central annular opening along a central longitudinal axis of the structural support member;

b. proximal and distal flange sections of the structural support member which project radially outward from proximal and distal sections of the structural support member, defining an intermediate support region between the proximal and distal flange sections; and

c. an occluding member for occluding the septal defect, the occluding member positioned within the intermediate support region of the structural support member transverse to the central longitudinal axis of the stent and occluding the central annular opening of the structural support member such that fluid does not pass through the occluding member, and wherein the occluding member further comprises a graft member.

8. The cardiac septal occluder prosthesis according to claim 7, wherein the graft member covers at least a portion of one of the luminal and abluminal surface of the structural support member.

9. The cardiac septal occluder prosthesis according to claim 7, wherein the graft member further comprises an inner graft member coupled to the luminal surface of the structural support member.

10. The cardiac septal occluder prosthesis according to claim 9, wherein the occluding member is coupled to the inner graft member.

11. The cardiac septal occluder prosthesis according to claim 9, wherein the graft member further comprises an outer graft member coupled to the abluminal surface of the structural support member.

12. The cardiac septal occluder prosthesis according to claim 7, wherein the proximal and distal flange sections are defined by a plurality of stent struts and interstices.

13. The cardiac septal occluder prosthesis according to claim 7, wherein the proximal and the distal flange project substantially perpendicular to the central longitudinal axis of the structural support member.
