Abstract

The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure and the other part is an expandable tubular mesh structure, is provided. In the first embodiment, the expandable sponge structure is intended to fill the aneurysm cavity to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure is placed across the aneurysm, contacting the inner wall of healthy vessel proximal and distal to the aneurysm.

Claims

1. A method for treatment of an aneurysm in a blood vessel having a flow of blood comprising:

positioning a balloon in the aneurysm, wherein the balloon has a longitudinal channel through the balloon and wherein the longitudinal channel is configured to allow the flow of blood to pass through the longitudinal channel; and

substantially fixably deploying the balloon in the aneurysm.

2. The method of claim 1, wherein substantially fixably deploying the balloon further comprising inflating the balloon with a fluid.

3. The method of claim 2, further comprising sealing the balloon.

4. The method of claim 3, wherein sealing the balloon comprises sealing with heat.

5. The method of claim 3, wherein sealing the balloon comprises sealing with an adhesive.

6. The method of claim 2, wherein the inflating the balloon occurs after the position the balloon.

7. The method of claim 2, wherein the fluid comprises a curable material.

8. The method of claim 7, wherein the curable material comprises an epoxy.

9. The method of claim 2, wherein the fluid comprises an epoxy.

10. The method of claim 2, wherein the fluid comprises a silicone.

11. The method of claim 2, wherein the fluid comprises a urethane.

12. The method of claim 2, further comprising substantially solidifying the fluid.

13. The method of claim 2, further comprising curing the fluid.

14. The method of claim 13, wherein the curing occurs after the positioning

15. The method of claim 13, wherein curing comprises curing with UV.

16. The method of claim 2, further comprising sealing the balloon.

17. The method of claim 2, wherein inflating comprises inflating the balloon until the balloon bulges out to fill substantially all of a sac of the aneurysm.

18. The method of claim 1, wherein substantially fixably deploying the balloon in the aneurysm comprises locking the balloon in the aneurysm.

19. The method of claim 1, further comprising sealing the balloon.

20. The method of claim 1, wherein the balloon is attached to a conduit

21. The method of claim 20, further comprising detaching the conduit from the balloon while the balloon is positioned in the aneurysm.

22. The method of claim 1, wherein substantially fixably deploying the balloon in the aneurysm comprises substantially preventing migration of the balloon.

23. A device for filling a sac of an aneurysm, wherein the aneurysm is in a blood vessel having a flow of blood, comprising:

a balloon defining a substantially closed volume, wherein the balloon has a longitudinal channel through the balloon and wherein the longitudinal channel is configured to allow the flow of blood to pass through the longitudinal channel; and

a hardened material in the substantially closed volume.

24. The device of claim 23, wherein the hardened material comprises a cured material.

25. The device of claim 23, wherein the balloon is porous.

26. The device of claim 23, wherein the balloon is non-porous.

27. The device of claim 23, wherein the balloon comprises PTFE.

28. The device of claim 23, wherein the balloon comprises polyester.

29. The device of claim 23, wherein the balloon comprises polyurethane.

30. The device of claim 23, wherein the balloon comprises silicone.

31. The device of claim 23, wherein the balloon comprises urethane.

32. The device of claim 23, wherein the balloon comprises latex.

33. The device of claim 23, wherein the cured material comprises an epoxy.

34. The device of claim 33, wherein the epoxy comprises a UV-curable epoxy.
