Abstract

An occlusion method and apparatus. The occluder includes a elastically deformable members and a jacket. The elastically deformable members are secured in spaced relation and extend in arcuate conformation therebetween. The jacket covers at least a portion of the elastically deformable members. The elastically deformable members are configured to become compressed upon application of a force and to recover the arcuate conformation upon removal of the force to occlude a site.

Claims

1-13. -13. (canceled)

14. An occlusion system comprising:

an occluder comprising;

a pair of clips;

a plurality of elastically deformable members secured by said clips and extending in arcuate conformation therebetween, said plurality of elastically deformable members operable to become compressed upon application of a force and to recover said arcuate conformation upon removal of said force;

a jacket covering an entire portion of said plurality of elastically deformable members; and

a delivery system comprising;

a guiding catheter configured to receive said occluder, said guiding catheter compressing and guiding said plurality of elastically deformable members; and

a pushing catheter configured to engage at least one of said pair of clips to slide said occluder relative to said guiding catheter.

15. The system of claim 14, wherein said plurality of elastically deformable members comprise four, five, or six nitinol wires.

16. The system of claim 14, wherein said plurality of elastically deformable members are programmed with thermal memory.

17. The system of claim 14, wherein said plurality of elastically deformable are programmed with superelasticity.

18. The system of claim 14, wherein said occluder further comprises one or more anchors defined by one or more ends of said plurality of elastically deformable wires.

19. The system of claim 14, wherein said jacket comprises DACRON.

20. The system of claim 14, where said jacket comprises polyurethane.

21. The system of claim 14, wherein said occluder further comprises an occluding agent enclosed within said jacket.

22. The system of claim 21, wherein said occluding agent comprises one or more threads of polyester.

23. The system of claim 14, wherein said occluder further comprises an eye in operable relation to at least one of said clips and wherein said delivery system further comprises a retrieval filament configured to engage said eye to retrieve said occluder.

24. The system of claim 14, wherein at least one of said clips is an interdigitated clip.

25. The system of claim 24, wherein an end of said pushing catheter is interdigitated and configured to removably interlock with said interdigitated clip.

26. The system of claim 14, further comprising a lumen defined through said occluder and said delivery system.

27. The system of claim 26, wherein said delivery system further comprises a guide wire within said lumen and passing through an interior of said occluder.

28. The system of claim 27, wherein said delivery system further comprises a stiffening catheter configured to engage at least one of said clips to compress said occluder.

43. The system of claim 27, wherein one or more of said plurality of elastically deformable members do not cross any other member.
