Abstract

Devices for occluding an aneurysm are provided. In particular, the device include an upper member that sits against the dome of the aneurysm, a lower member that sits in the neck of the aneurysm, and a means of adjusting the overall dimensions of the device. Also provided are methods of making and using these devices.

Claims

1. A vaso-occlusive device for placement within an aneurysm having a neck and a dome, the device comprising

a lower member having a linear configuration prior to deployment and a deployed open configuration, wherein the deployed configuration bridges the neck of the aneurysm;

an upper member having a undeployed, linear configuration prior and an open, deployed configuration, wherein the deployed configuration rests against at least a portion of the dome of the aneurysm, and

a means of adjusting the overall dimensions of the device.

2. The device of claim 1, wherein the distance between the upper and lower members is adjustable.

3. The device of claim 1, wherein the upper and lower members are contiguous.

4. The device of claim 1, wherein one or both of the upper member and lower member are compressible.

5. The device of claim 1, wherein the upper and lower members are separate, the device further comprising an adjustable central member having a proximal end connected to the lower member and distal end connected to the upper member.

6. The device of claim 5, wherein the central member comprises a compressible element.

7. The device of claim 5, wherein the central member comprises an extendable member connected to the upper member.

8. The device of claim 5, wherein the central member comprises an expandable element.

9. The device of claim 1, wherein the upper member comprises a plurality of axially moveable wires passing through the lumen of the central member, each wire comprising a distal end and a proximal end.

10. The device of claim 9, wherein the distal end of one or more of the wires is attached to the central member.

11. The device of claim 9, wherein the distal end of one or more of the wires is attached to the lower member.

12. The device of claim 1, wherein the lower and/or upper members comprise a braid configuration.

13. The device of claim 1, wherein the upper and lower members are contiguous.

14. The device of claim 1, further comprising one or more detachment junctions.

15. The device of claim 14, wherein at least one detachment junction comprises an electrolytically detachable end adapted to detach by imposition of a current thereon.

16. The device of claim 14, comprising a detachment junction positioned between the upper member and a pusher wire and one or more detachment junctions positioned between the lower member and a pusher tube.

17. The device of claim 1, further comprising one or more locking mechanisms.

18. The device of claim 17, wherein the locking mechanism comprises an expandable material.

19. The device of claim 17, wherein the locking mechanism comprises a self-expanding element.

20. The device of claim 1, wherein the upper member comprises a metal.

21. The device of claim 20, wherein the metal is selected from the group consisting of nickel, titanium, platinum, gold, tungsten, iridium and alloys or combinations thereof.

22. The device of claim 21, wherein the alloy is nitinol.

23. The device of claim 1, wherein the lower member comprises a metal selected from the group consisting of platinum, palladium, rhodium, gold, tungsten and alloys thereof.

24. The device of claim 23, wherein the lower member comprises nitinol.

25. The device of claim 23, wherein the lower member comprises a mesh or braid structure.

26. The device of claim 1, wherein the lower member comprises a film.

27. The device of claim 26, wherein the film is selected from the group consisting of a porous film, a polymer film and a metallic film.

28. The device of claim 1, further comprising an additional component.

29. The device of claim 28, wherein the additional component is bioactive.

30. A method of occluding a body cavity comprising introducing a vaso-occlusive device according to claim 1 into the body cavity.

31. The method of claim 29, wherein the body cavity is an aneurysm.
