Abstract

An endoluminal device including a prosthesis and at least one indicator member affixed to the prosthesis that can be remotely monitored to indicate a change in pressure or morphology of the prosthesis. The indicator member may be an optical fiber, a strain gauge, or a first material having a first magnetic resonance imaging (MRI) susceptibility value that contrasts with a second MRI susceptibility value of a second material that comprises one or more remaining members of the prosthesis. A prosthesis monitoring system includes an endoluminal device as well as a subcutaneous electronics package and external electronics. Methods of detecting endoleaks or changes in morphology involve implanting an endoluminal device with the indicator and detecting information from the indicator.

Claims

1. An endoluminal device comprising a prosthesis and at least one indicator member affixed to the prosthesis, the indicator member comprising an optical fiber adapted to be remotely monitored to indicate a change in pressure or morphology of the prosthesis.

2. The device of claim 1, wherein the prosthesis comprises a stent and the indicator member is woven into the stent.

3. The device of claim 2, wherein the prosthesis comprises a graft.

4. The device of claim 3, wherein the indicator member is woven into the graft.

5. The device of claim 1, wherein the indicator member is longitudinally along the prosthesis.

6. The device of claim 1, wherein the indicator member runs helically, circumferentially, or radially along the prosthesis.

7. The device of claim 1, wherein the optical fiber is configured to measure bending of the optical fiber.

8. The device of claim 1, wherein the optical fiber comprises an optical sensor at a distal end of the optical fiber.

9. The device of claim 1, wherein the optical fiber comprises a pressure transducer.

12. The device of claim 1 wherein the prosthesis comprises a graft.

13. The device of claim 12 wherein the indicator member is woven into the graft.

10. An endoluminal device comprising a prosthesis and at least one indicator member affixed to the prosthesis, the indicator member comprising a first material having a first magnetic resonance imaging (MRI) susceptibility value that contrasts with a second MRI susceptibility value of a second material that comprises one or more remaining members of the prosthesis, the indicator member adapted to be remotely monitored to indicate a change in morphology of the prosthesis.

11. The device of claim 10 wherein the prosthesis comprises a stent and the indicator member is woven into the stent.

14. The device of claim 10 wherein the indicator member runs longitudinally along the prosthesis.

15. The device of claim 10 wherein the indicator member runs helically, circumferentially, or radially along the prosthesis.

16. The device of claim 10, wherein the indicator comprises a filamentary member within the prosthesis.

17. The device of claim 10, wherein the indicator comprises a non-redundant filamentary member.

18. The device of claim 10, wherein the first material of the indicator member has a positive MRI susceptibility value and second material of the one or more remaining members of the prosthesis has a negative MRI susceptibility value.

19. The device of claim 10, wherein the first material of the indicator member has a negative MRI susceptibility value and the second material of the one or more remaining members of the prosthesis has a positive MRI susceptibility value.

20. An endoluminal device comprising a prosthesis and at least one indicator member affixed to the prosthesis, wherein the indicator member is adapted to be remotely monitored to indicate a change in pressure or morphology of the prosthesis, the indicator member comprising an optical fiber, a strain gauge, or a first material having a first magnetic resonance imaging (MRI) susceptibility value that contrasts with a second MRI susceptibility value of a second material that comprises one or more remaining members of the prosthesis, the prosthesis comprising a stent having an aortic trunk and at least one iliac leg in which the indicator member is woven into the at least one iliac leg.

21. An endoluminal device comprising a prosthesis and at least one indicator member affixed to the prosthesis and adapted to be remotely monitored to indicate a change in pressure or morphology of the prosthesis, the prosthesis comprising a graft and a stent with the indicator member sandwiched between the graft and the stent.
