Abstract

Intraluminal support frames for placement within a body vessel are provided. The support frames include a plurality of ring structures and first and second sets of connector segments. Connector segments of the first set join adjacent pairs of ring structures while connector segments of the second set join at least three ring structures. Medical devices are also provided that include a support frame and an additional component, such as a graft member or valve member.

Claims

1. A medical device for regulating fluid flow through a body vessel, said medical device comprising:

an intraluminal support frame comprising a plurality of ring structures joined by first and second sets of connector segments, each of the first set of connector segments joining an adjacent pair of the plurality of ring structures and each of the second set of connector segments joining at least three ring structures of the plurality of ring structures; and

a valve member attached to the support frame and forming a valve opening that opens to permit fluid flow through the support frame in a first direction and closes to substantially prevent fluid flow through the support frame in a second, opposite direction.

2. A medical device according to claim 1, wherein each connector segment of the second set of connector segments is spaced from at least one connector segment of the first set of connector segments by at least one peak in the undulating pattern of a ring structure.

3. A medical device according to claim 1, wherein each connector segment of the second set of connector segments is spaced from at least one connector segment of the first set of connector segments by at least two peaks in the undulating pattern of a ring structure.

4. A medical device according to claim 1, wherein the second set of connector segments comprises first and second connector segments diametrically disposed on said support frame.

5. A medical device according to claim 1, wherein each connector segment of the second set of connector segments joins all ring structures of the plurality of ring structures.

6. A medical device according to claim 1, wherein each connector segment of the second set of connector segments joins less than all of the ring structures of the plurality of ring structures.

7. A medical device according to claim 1, wherein each connector segment of the second set of connector segments joins less than half of the ring structures of the plurality of ring structures.

8. A medical device according to claim 1, wherein each connector segment of the second set of connector segments joins less than one third of the ring structures of the plurality of ring structures.

9. A medical device according to claim 1, wherein the support frame comprises first and second axial portions, the first axial portion including connector segments of both the first and second sets of connector segments and the second axial portion including connector segments of only the first set of connector segments.

10. A medical device according to claim 1, wherein the plurality of ring structures comprises first and second pairs of adjacent ring structures;

wherein the first pair of adjacent ring structures is joined by a first number of connector segments of the first set of connector segments;

wherein the second pair of adjacent ring structures is joined by a second number of connector segments of the first set of connector segments;

wherein the first number is different than the second number.

11. A medical device according to claim 1, wherein the valve member comprises a bioremodellable material.

12. A medical device according to claim 1, wherein the valve member comprises an extracellular matrix material.

13. A medical device according to claim 1, wherein the valve member comprises small intestine submucosa.

14. A medical device according to claim 1, wherein the valve member comprises a tubular member attached to the support frame.

15. A medical device according to claim 1, wherein the valve member comprises a tissue valve.

16. A medical device according to claim 15, wherein the tissue valve comprises a heart valve.

17. A medical device for regulating fluid flow through a body vessel, said medical device comprising:

an intraluminal support frame comprising a plurality of ring structures joined by first and second sets of connector segments, each of the first set of connector segments joining an adjacent pair of the plurality of ring structures and each of the second set of connector segments joining at least three ring structures of the plurality of ring structures; and

a tubular valve member attached to the support frame to form a valve opening that opens to permit fluid flow through the support frame in a first direction and closes to substantially prevent fluid flow through the support frame in a second, opposite direction.

18. A medical device according to claim 17, wherein the tubular valve member comprises a bioremodellable material.

19. A medical device according to claim 17, wherein the tubular valve member comprises an extracellular matrix material.

20. A medical device for regulating fluid flow through a body vessel, said medical device comprising:

an intraluminal support frame comprising first and second axial portions and a plurality of ring structures joined by first and second sets of connector segments, each of the first set of connector segments joining an adjacent pair of the plurality of ring structures and each of the second set of connector segments joining at least three ring structures of the plurality of ring structures, the first axial portion including connector segments of both the first and second sets of connector segments and the second axial portion including connector segments of only the the first set of connector segments; and

a valve member attached to the support frame and forming a valve opening that opens to permit fluid flow through the support frame in a first direction and closes to substantially prevent fluid flow through the support frame in a second, opposite direction.
