Abstract

The disclosure is directed to a material for in vivo implantation. The material includes a compressed interlaced wire shaped into a form having a porous structure suitable for tissue ingrowth, the interlaced wire compressed from an original starting density to a final density, the final density being greater than the original starting density.

Claims
