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.

Abstract
Disclosed herein is a catheter for use in an emboli containment system. In one embodiment, the catheter includes a flexible elongate member having self-expanding sealing means mounted on its distal extremity. This self-expanding sealing means can take any suitable form, such as a braided structure formed of a suitable shape memory material such as a nickel titanium alloy. In order to prevent abrasion of a vessel, it is desirable to cover the braided structure with a covering of a suitable material such as a polymer which extends over the braided structure and which moves with the braided structure as it expands and contracts.

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. - View Dependent Claims (7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 18, 20, 21)

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.

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.
