ABSTRACT:
Improved Implant assemblies and methodologies provide immuno-protection for implanted allografts, xenografts, and isografts. The assemblies and methodologies establish an improved chamber for holding the implanted cells. The chambers include first and second wall elements and an intermediate sealing element. The first and second wall elements overlie an open area in the sealing member to form a chamber for holding cells for implantation. A sealed region is created between the wall elements and the sealing element body to close the chamber. In one arrangement, the sealed region is created by means of a sonic weld made while the implanted cells are present in the chamber. In another arrangement, the sealed region is created by means of applying an external force to compress the peripheral edges of the wall elements and the sealing element together while the implanted cells are present in the chamber.
