T I T L E CARDIAC AND VASCULAR PROSTHESES AND METHODS OF MAKING THE SAME 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 characteris- tic 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 de- sired 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 prosthe- sis. In still another type of prosthesis, agar is applied to the prosthesis in conjunction with gelatin. In another type of pros- thesis, albumin is applied to the prosthesis. FEILD OF INVENTION This invention relates to cardiac and vascular pros- theses and methods of making the same and materials therefor. -2-
