SUPPORT STRUCTURE IMPLANT FOR A BONE CAVITY
First Claim
1. A method of making a stranded support structure implant for location within a bone cavity to support the bone which defines the cavity, comprising the steps of:
- a. forming loops in a plurality of wires so that two lengths of each wire extend from each loop and fastening the loops against a support,b. braiding the two lengths of each of the wires to form the support structure having a first end provided by the loops in the wires and an opposite second end,c. clamping each of the wires at the second end of the support structure so as to retain the braided structure.

Abstract
A support structure implant for location within a bone cavity to support the bone which defines the cavity is formed from wires by braiding in a machine direction from a first end of the structure towards an opposite second end. The wires are formed into loops at the first end of the structure so that two lengths of wire extend away from each loop and are formed into the braid. Each of the wires which is formed into the braid is held at the second end of the structure in a clamp. The clamp is provided by a support ring and a clamp ring which is formed from a shape memory alloy which can shrink to clamp the wires against the support ring when heated.

15. A support structure implant for location within a bone cavity to support the bone that defines the cavity, wherein the structure is formed from wires by braiding in a machine direction from a first end of the structure towards an opposite second end, and wherein each of the wires formed into the braid is held at the second end of the structure in a clamp that comprises a support and a shape memory alloy clamp ring which can clamp the wires between the ring and the support.

16. A method of making a stranded support structure implant for location within a bone cavity to support the bone which defines the cavity, which comprises:
-
a. braiding a plurality wires to form the support structure from a first end to an opposite second end, b. positioning the wires at the second end of the support structure between a support and a shape memory alloy clamp ring, and causing the shape memory alloy clamp ring to clamp the wires between the ring and the support so as to retain the braided structure.
