Abstract

An occlusion device comprises a bioabsorbable material, which allows the occlusion device to effectively close a defect in the heart while eliminating or limiting components which permanently remain in the body.

Claims

1. An occlusion device comprising:

first and second support frames comprising a plurality of arms;

a center post extending between the first and second support frames;

first and second sheets attached to the first and second support frames, respectively; and

wherein the occlusion device is comprised at least in part of a bioabsorbable material.

2. The occlusion device of claim 1 wherein the bioabsorbable material comprises a polymer.

3. The occlusion device of claim 2 wherein the polymer includes at least one of the following:

a polylactide, a polyglycolide, a polycaprolactone, a polycarbonate, a polydioxanone, and a polyactive.

4. The occlusion device of claim 1 wherein the bioabsorbable material comprises collagen.

5. The occlusion device of claim 1 wherein the occlusion device further comprises a radiopaque material.

6. The occlusion device of claim 1 wherein the bioabsorbable material includes a deliverable biologically active agent.

7. An occlusion device comprising:

a center post;

first and second collapsible support frames connected to the center post; and

a first sheet formed of a bioabsorbable material attached to the first collapsible support frame.

8. The occlusion device of claim 7 and comprising a second sheet formed of a bioabsorbable material attached to the second collapsible support frame.

9. The occlusion device of claim 8 wherein the center post is formed of a bioabsorbable material.

10. The occlusion device of claim 7 wherein the center post is formed of a bioabsorbable material.

11. The occlusion device of claim 10 wherein the first and second collapsible support frames are formed of a bioabsorbable material.

12. The occlusion device of claim 11 wherein the first and second collapsible support frames include a radiopaque material.

13. The occlusion device of claim 7 wherein the bioabsorbable material comprises a polymer.

14. The occlusion device of claim 13 wherein the polymer includes at least one of the following:

a polylactide, a polyglycolide, a polycaprolactone, a polycarbonate, a polydioxanone, and a polyactive.

15. The occlusion device of claim 7 wherein the bioabsorbable material comprises collagen.

16. The occlusion device of claim 7 wherein the bioabsorbable material includes a deliverable biologically active agent.

17. An occlusion device comprising:

a first fixation device configured to be placed on a first side of a septal defect, the first fixation device comprising a plurality of arms, each arm including an atraumatic tip;

a second fixation device configured to be placed on a second side of a septal defect, the second fixation device comprising a plurality of arms, each arm including an atraumatic tip; and

a center post connecting the first fixation device and the second fixation device;

first and second bioabsorbable sheets attached to the first and second fixation devices, respectively.

18. The occlusion device of claim 17 wherein the first and second bioabsorbable sheets are comprised of a polymer.

19. The occlusion device of claim 17 wherein the first and second bioabsorbable sheets are comprised of collagen.

20. The occlusion device of claim 17 wherein the center post is formed of a bioabsorbable material.

21. The occlusion device of claim 17 wherein the first and second fixation devices are formed of a bioabsorbable material.

22. The occlusion device of claim 17 wherein the center post and the first and second fixation devices are formed of a bioabsorbable material.
