Abstract
A prosthesis suitable for implantation in a bloody environment. The prosthesis includes a surface material adapted for exhibiting a regular and periodic surface charge characteristic in the bloody environment. A prosthesis means supports the surface material and is adapted to perform a prosthetic function in the bloody environment. In cases where cross-linking is desired and the surface material cannot cross-link with the substrate material, an adaptive material is provided which cross-links both to the surface material and to the material of the prosthesis. In one type of prosthesis, the surface material is aluminized. In another type of prosthesis, acrylamide is applied to the prosthesis. In still another type of prosthesis, agar is applied to the prosthesis in conjunction with gelatin. In another type of prosthesis, albumin is applied to the prosthesis.
