Claims
- 1. An apparatus for occlusion of a vessel, the apparatus comprising:
a flexible elongate member having a distal extremity; and an expandable and contractible metallic braided structure having first and second ends, both the first and second ends being mounted on the distal extremity, the braided structure having a covering thereon, the covering being movable with the braided structure during expansion thereof and being capable of substantial sealing engagement with a wall of the vessel to interrupt fluid flow there through.
- 2. The apparatus of claim 1, wherein the braided structure is self-expanding.
- 3. The apparatus of claim 2, further comprising an elongate sleeve, the sleeve being slidable over the braided structure for contraction thereof.
- 4. The apparatus of claim 1, wherein the elongate member has a lumen extending there through.
- 5. The apparatus of claim 1, wherein the covering is movable with the braided structure during expansion and contraction thereof.
- 6. An apparatus for temporary occlusion of a blood vessel, the apparatus comprising:
a flexible elongate member having a distal extremity; a structure having first and second ends mounted on the distal extremity and having contracted and expanded configurations; and a covering on the structure, the covering being movable with the structure during expansion thereof and being capable of substantial sealing engagement with a wall of the blood vessel to interrupt blood flow there through, the structure and the covering being non-inflatable between the contracted and expanded configurations.
- 7. The apparatus of claim 6, wherein the structure comprises a braid.
- 8. The apparatus of claim 7, wherein the braid comprises a metal.
- 9. The apparatus of claim 6, wherein the structure is self-expanding.
- 10. The apparatus of claim 9, further comprising an elongate sleeve, the sleeve being slidably disposed over the structure for contraction thereof.
- 11. The apparatus of claim 6, wherein the covering is moveable with the structure during expansion and contraction thereof.
- 12. The apparatus of claim 6, wherein the covering expands and contracts with the structure.
- 13. An apparatus for occlusion of a vessel, the apparatus comprising:
a flexible elongate member having a distal extremity; a braided structure having first and second ends, both the first and second ends being mounted about the distal extremity, the structure being movable between a contracted shape and an expanded shape; and a covering being located on and movable with the braided structure such that, when the braided structure is in the expanded shape, the covering substantially seals against a wall of the vessel to interrupt fluid flow there through, the braided structure and the covering being non-inflatable between the contracted and expanded shapes.
- 14. The apparatus of claim 13, wherein the braided structure has a shape memory.
- 15. The apparatus of claim 14, wherein the shape memory is the expanded shape.
- 16. The apparatus of claim 15, further comprising an elongate sleeve, the sleeve being slidably disposed over the braided structure for encasing the braided structure in the contracted shape.
- 17. The apparatus of claim 13, wherein the braided structure comprises a material selected from the group consisting of shape memory metal, nickel titanium alloy, stainless steel and titanium.
- 18. The apparatus of claim 13, wherein the covering comprises a material selected from the group consisting of silicone, C-Flex, polyethylene and PET.
- 19. An apparatus for occlusion of a blood vessel, the apparatus comprising:
a flexible elongate member having a distal extremity; and means for sealing having first and second ends, both the first and second ends being mounted on the distal extremity, the means for sealing being capable of self-expansion into sealing engagement with a wall of the blood vessel to interrupt blood flow there through.
- 20. The apparatus of claim 19, wherein the means for sealing comprises an expandable and contractible braided structure with a covering thereon, the covering being movable with the braided structure during expansion and contraction thereof.
- 21. The apparatus of claim 19, wherein the means for sealing comprises an absorbent material which, when it absorbs blood, expands to form a seal with a wall of the blood vessel.
