Abstract

A self-expanding implantable medical device formed from one or more non-interlocking filaments. Stents, stent-grafts, occluder devices, and filters are manufactured from one or more filaments utilizing a non-interlocking crossing pattern.

First claim

We claim:

1. An implantable device comprising a filament-wound tubular structure including non-interlocking wound filaments that are wound on top of a previously wound filament and do not pass underneath the previously wound filament and having a longitudinal axis wherein the tubular structure has been formed into a shape having a pair of opposing planar forms each having a generally circular shape oriented to be substantially transverse to the longitudinal axis, said opposing planar forms having a diameter and interconnected by a waist having a diameter less than the diameters of the opposing planar forms.

2. An implantable device according to claim 1 wherein the waist includes an orifice extending through a center portion thereof.

3. An implantable device according to claim 2 wherein the device is formed of a single filament.

4. An implantable device according to claim 3 wherein the device is formed of a single filament.

5. An implantable device according to claim 4 wherein the device is removable from a body in which it has been implanted by being withdrawn into a catheter.

6. An implantable device according to claim 5 wherein the device is removable by being disassembled and withdrawn into the catheter.

7. An implantable device according to claim 1 wherein the device is removable from a body in which it has been implanted by being withdrawn into a catheter.

8. An implantable device according to claim 1 wherein the device is removable intact by being withdrawn into a catheter.

9. An implantable device according to claim 2 wherein the device is removable intact by being withdrawn into a catheter.

10. An implantable device according to claim 3 wherein the device is removable intact by being withdrawn into a catheter.

11. An implantable device according to claim 1 wherein the device further comprises a graft covering material over an outer surface of the device.

12. An implantable device according to claim 11 wherein the graft covering material comprises ePTFE.

13. An implantable device according to claim 1 wherein the device further comprises a graft covering material over an inner surface of the device.

14. An implantable device according to claim 13 wherein the graft covering material comprises ePTFE.

15. An implantable device according to claim 1 wherein the device further comprises a graft covering material over both an outer surface and inner surface of the device.

16. An implantable device according to claim 15 wherein the graft covering material comprises ePTFE.

17. An implantable device comprising a self-expanding filament-wound tubular structure having a circumference and a crossing pattern of at least one filament having a length, wherein said filament includes a multiplicity of filament portions separated by apices along its length, said apices comprising bent portions of said filaments located only at opposing ends of said tubular structure, wherein the crossing pattern is non-interlocking and includes multiple crossover points along a length of a filament portion wherein the filament is wound only on top of previously wound filament and does not pass underneath previously wound filament such that the filament is not woven or braided, and wherein no filament portion extends around the entire circumference of the tubular structure wherein the tubular structure has been formed into a shape having a pair of opposing planar forms each having a generally circular shape and interconnected by a waist.

18. An implantable device according to claim 17 wherein the waist includes an orifice extending through a center portion thereof.

19. An implantable device according to claim 18 wherein the device is formed of a single filament.

20. An implantable device according to claim 19 wherein the device is formed of a single filament.

21. An implantable device according to claim 20 wherein the device is removable from a body in which it has been implanted by being withdrawn into a catheter.

22. An implantable device according to claim 21 wherein the device is removable by being disassembled and withdrawn into the catheter.

23. An implantable device according to claim 17 wherein the device is removable from a body in which it has been implanted by being withdrawn into a catheter.

24. An implantable device according to claim 17 wherein the device is removable intact by being withdrawn into a catheter.

25. An implantable device according to claim 18 wherein the device is removable intact by being withdrawn into a catheter.

26. An implantable device according to claim 19 wherein the device is removable intact by being withdrawn into a catheter.

27. An implantable device according to claim 17 wherein the device further comprises a graft covering material over an outer surface of the device.

28. An implantable device according to claim 27 wherein the graft covering material comprises ePTFE.

29. An implantable device according to claim 17 wherein the device further comprises a graft covering material over an inner surface of the device.

30. An implantable device according to claim 29 wherein the graft covering material comprises ePTFE.

31. An implantable device according to claim 17 wherein the device further comprises a graft covering material over both an outer surface and inner surface of the device.

32. An implantable device according to claim 31 wherein the graft covering material comprises ePTFE.
