Abstract

Embodiments of the present invention provide devices and methods for treating abnormalities. For example, a device according to one embodiment includes a plurality of planes of occlusion, at least one plane of occlusion comprising a plurality of layers of occlusive material. The device is configured to at least partially occlude an abnormality.

Claims

1. A medical device for occluding an abnormality, the medical device comprising:

a plurality of planes of occlusion, at least one of the planes of occlusion comprising a plurality of layers of occlusive material, wherein the medical device is configured to substantially occlude the abnormality in less than about 10 minutes.

2. The medical device of claim 1, wherein the medical device is configured to substantially occlude the abnormality in less than about 5 minutes.

3. The medical device of claim 1, wherein the medical device is configured to substantially occlude the abnormality in less than about 3 minutes.

4. The medical device of claim 1, wherein the medical device comprises at least four planes of occlusion.

5. The medical device of claim 1, wherein at least one of the plurality of layers of occlusive material comprises a layer of braided metal fabric

6. The medical device of claim 1, wherein at least one of the plurality of planes of occlusion comprises at least three layers of occlusive material.

7. The medical device of claim 1, wherein at least one of the plurality of planes of occlusion is configured to overlie an opening of the abnormality.

8. The medical device of claim 1, wherein at least one of the plurality of planes of occlusion is configured to be at least partially positioned within an opening defined by the abnormality.

9. The medical device according to claim 12, wherein at least one of the plurality of planes of occlusion is oval or crescent shaped.

10. The medical device according to claim 1, wherein at least one of the plurality of planes of occlusion is non-circular in shape.

11. The medical device of claim 1, wherein the plurality of planes of occlusion are configured to be oriented generally transverse to the flow of blood so as to facilitate the formation of thrombus.

12. The medical device of claim 1, wherein the medical device is configured for delivery over a guide wire.

14. The medical device of claim 12, wherein at least one of the plurality of planes of occlusion is configured to be positioned within a first vessel or an organ, at least one of the plurality of planes of occlusion is configured to be positioned within a second vessel or an organ, and at least one of the plurality of layers of occlusion is configured to be positioned within an opening extending between the first and second vessels or organs.

15. The medical device of claim 12, wherein each of the plurality of layers of occlusive material comprises a layer of braided metal fabric.

16. The medical device of claim 12, wherein each of the plurality of layers of occlusive material comprises Nitinol.

17. The medical device according to claim 12, wherein at least one of the plurality of planes of occlusion is oval or crescent shaped.

18. The medical device according to claim 12, wherein at least one of the plurality of planes of occlusion is non-circular in shape.

19. The medical device of claim 12, wherein the plurality of planes of occlusion are configured to be oriented generally transverse to the flow of blood so as to facilitate the formation of thrombus.

13. A medical device for occluding an abnormality comprising:

a plurality of planes of occlusion, at least one plane of occlusion comprising a plurality of layers of occlusive material, wherein at least one of the plurality of planes of occlusion is configured to be positioned within a vessel or an organ and overlie an opening of the abnormality, and wherein at least one of the plurality of planes of occlusion is configured to be at least partially positioned within the opening defined by the abnormality.

20. A medical device for occluding an abnormality, the medical device comprising:

a plurality of planes of occlusion, at least one plane of occlusion comprising a plurality of layers of occlusive material, wherein the medical device is configured to be delivered through a catheter having an outer diameter of less than 9 French for percutaneous delivery to the vascular abnormality.

21. The medical device of claim 20, wherein the medical device is configured to be delivered through a catheter having an outer diameter of less than 7 French for percutaneous delivery to the vascular abnormality.

22. The medical device of claim 20, wherein the medical device is configured to be delivered through a catheter having an outer diameter of less than 6 French for percutaneous delivery to the vascular abnormality.

23. The medical device of claim 20, wherein the medical device is configured to be delivered through a catheter having an outer diameter of less than 5 French for percutaneous delivery to the vascular abnormality.

24. The medical device of claim 20, wherein each of the plurality of planes of occlusive material comprises a layer of braided metal fabric.

25. The medical device of claim 20, wherein each of the plurality of layers of occlusive material comprises Nitinol.

26. A method for occluding an abnormality with a medical device, the method comprising:

constraining a medical device to a smaller diameter than an expanded preset configuration, wherein the medical device comprises a plurality of planes of occlusion, at least one plane of occlusion comprising a plurality of layers of occlusive material;

delivering the medical device proximate to the abnormality; and

deploying the medical device proximate to the abnormality such that the plurality of planes of occlusion at least partially occlude the abnormality.

27. The method of claim 26, wherein constraining comprises stretching the medical device along a longitudinal axis thereof to the smaller diameter.

28. The method of claim 26, wherein deploying comprises deploying the medical device such that at least one of the plurality of planes of occlusion is configured to overlie an opening of the abnormality.

29. The medical device of claim 26, wherein deploying comprises deploying the medical device such that at least one of the plurality of layers of occlusion is at least partially positioned within an opening defined by the abnormality.

30. The method of claim 26, wherein delivering comprises delivering the medical device over a guide wire.

31. The method of claim 26, wherein deploying comprises deploying the medical device such that the plurality of planes of occlusion are oriented generally transverse to the flow of blood so as to facilitate the formation of thrombus.

32. The method of claim 26, wherein delivering comprises delivering the device arterially or venously proximate to the abnormality.
