Claim:
1. A compression apparatus comprising: a body formed by a first U-shaped bolt and a second U-shaped bolt disposed in an inverted position relative to the first U-shaped bolt, the body having a first end and a second end, wherein a first cap is disposed at the first end, a second cap is disposed at the second end and a first internal space is disposed between the first cap and the second cap, wherein legs of the first U-shaped bolt are disposed through the first cap and the second cap and further wherein the legs of the first U-shaped bolt are rigidly held to the second cap, wherein legs of the second U-shaped bolt are disposed through the second cap and the first cap and further wherein the legs of the second U-shaped bolt are rigidly held to the first cap; a first compressible material within the first space between the first cap and the second cap; wherein the first compressible material has first and second internal elements, wherein the first internal element contributes to the compressibility of the compression apparatus at a first force applied to the compression apparatus and further wherein a combination of the first internal element and the second internal element contributes to the compressibility of the compression apparatus at a second force applied to the compression apparatus, wherein the first internal element has an open volume therein, and the second internal element is disposed in the open volume within the first internal element.
