Abstract

An occlusion device for occluding a body vessel and methods of using the device are disclosed.

First claim

The invention claimed is:

1. An occlusion device for occluding a body vessel comprising:
a proximal end,
a distal end spaced from the proximal end along a longitudinal axis,
an occluding member disposed between the proximal end and distal end, the occluding member moveable between a radially-outwardly expanded configuration and a contracted configuration,
a first biasing member disposed within the occluding member and having a first end adjoined to the proximal end of the device,
a second biasing member disposed within the occluding member and having a first end adjoined to the distal end of the device, the second biasing member configured to releasably engage the first biasing member, such that in a first configuration the first and second biasing members are engaged and in a second configuration the first and second biasing members are disengaged.

2. The occlusion device of claim 1 wherein when proximal and distal ends are moved towards each other along the longitudinal axis, the occlusion member is moveable to the expanded configuration, and when proximal and distal ends are moved away from each other along the longitudinal axis, the occlusion member is moveable to the contracted configuration.

3. The occlusion device of claim 1 wherein at least one of the first and second biasing members is rotatable with respect to the other biasing member.

4. The occlusion device of claim 1 wherein each of the first and second biasing members is a helical coil.

5. The occlusion device of claim 1 wherein each of the first and second biasing members is threaded.

6. The occlusion device of claim 1 wherein the occluding member comprises a woven mesh.

7. The occlusion device of claim 6 wherein the self-expanding material and polyester fiber are woven in a ratio of at least one of 1:1; 1:2; 1:3; 1:4; 2:1; 3:1 and 4:1.

8. The occlusion device of claim 7 wherein the self-expanding material and polyester fiber are woven in a ratio of at least one of 1:1.

9. The occlusion device of claim 1 wherein at least one of the proximal and distal ends comprises a radiopaque material.

10. The occlusion device of claim 9 wherein each of the proximal and distal ends comprises a radiopaque material.
