Abstract
A tantalum open cell structure is formed by chemical vapor deposition onto a reticulated carbon foam substrate. Tantalum has a long history of use as an implant material, in both bone and soft tissue. This lightweight, strong, porous structure, mimicking the microstructure of natural cancellous bone, acts as a matrix for the incorporation of bone, providing optimal permeability and a high surface area to encourage new bone ingrowth.
