Abstract
Improved Implant assemblies and methodologies provide immuno-protection for implanted allografts, xenografts, and isografts. The assemblies and methodologies establish an improved boundary between the host and the implanted cells. The boundary structure is laminated, combining elements having different characteristics beneficial to the survival of the implanted cells. Filaments of adhesive material lay in between the elements. The filaments of adhesive material have been melted in place by the application of heat and solidified in place by cooling to secure the elements together into a composite laminated structure.
