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 having an aneurysm sac, the aneurysm in a blood vessel having a flow of blood, the method comprising:

positioning a device in the aneurysm, wherein the device has a first longitudinal end and a second longitudinal end, and wherein the device comprises a balloon having a chamber, and wherein the chamber has an inner wall and an outer wall, and wherein the inner wall is positioned in contact with the flow of blood and the outer wall is positioned in contact with the aneurysm sac and wherein the device is attached to a conduit, and wherein the first longitudinal end and the second longitudinal end are positioned outside of the aneurysm sac, and wherein the device comprises a stent that extends continuously from the first longitudinal end to the second longitudinal end; and

detaching the conduit from the device while the balloon is in the aneurysm sac.

2. The method of claim 1, wherein the device comprises a connector comprising a communication port, further comprising attaching the connector to the conduit before positioning the device in the aneurysm.

3. The method of claim 1, further comprising inflating the balloon with a fluid.

4. The method of claim 3, wherein the inflating the balloon occurs after the positioning of the device.

5. The method of claim 3, wherein the fluid comprises a curable material.

6. The method of claim 5, wherein the curable material comprises an epoxy.

7. The method of claim 3, wherein the fluid comprises an epoxy.

8. The method of claim 3, wherein the fluid comprises a silicone.

9. The method of claim 3, wherein the fluid comprises a urethane.

10. The method of claim 3, further comprising curing the fluid.

11. The method of claim 10, wherein the curing comprises curing with UV.

12. The method of claim 10, further comprising sealing the balloon.

13. The method of claim 3, further comprising substantially solidifying the fluid.

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

15. The method of claim 1, wherein the device has a longitudinal channel through the device and wherein the longitudinal channel is configured to allow the flow of blood to pass through the longitudinal channel.

16. A method for treatment of an aneurysm having an aneurysm sac, the aneurysm in a blood vessel having a flow of blood, the method comprising:

positioning a device in the aneurysm, wherein the device has a first longitudinal end and a second longitudinal end, and wherein the device comprises a balloon and a non-inflatable graft, and wherein the balloon is radially outside of the graft, and wherein the device is attached to a conduit, and wherein the first longitudinal end and the second longitudinal end are positioned outside of the aneurysm sac, and wherein the device comprises a stent that extends continuously from the first longitudinal end to the second longitudinal end; and

detaching the conduit from the device while the balloon is in the aneurysm sac.

17. The method of claim 16, wherein the balloon has a chamber, and wherein the chamber has an inner wall and an outer wall, and wherein the inner wall is positioned in contact with the graft and the outer wall is positioned in contact with the aneurysm sac.

18. The method of claim 16, wherein the graft is positioned in contact with the flow of blood.

19. 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, 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;

a stent that extends continuously from a first longitudinal end of the device to a second longitudinal end of the device; and

a conduit removably attached to the balloon, wherein the conduit is in fluid communication with the balloon.

20. The device of claim 19, further comprising a communication port, and wherein the communication port is configured to attach the conduit to the balloon.

21. The device of claim 19, wherein the balloon defines a substantially closed volume, and wherein the device further comprises a fluid in the substantially closed volume.

22. The device of claim 21, wherein the fluid is hardenable.

23. The device of claim 21, wherein the fluid is curable.

24. The device of claim 21, wherein the fluid comprises a polymer.

25. The device of claim 21, wherein the fluid comprises an epoxy.

26. The device of claim 19, wherein the balloon defines a substantially closed volume, and further comprising a hardened material in the substantially closed volume.

27. The device of claim 26, wherein the hardened material comprises a cured material.

28. The device of claim 26, wherein the hardened material comprises a polymer and/or an epoxy.

29. The device of claim 19, wherein the balloon is porous.

30. The device of claim 19, wherein the balloon is non-porous.
