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 has a pore size, an ultimate strength, and a metabolic transit value that assures the survival of the cells during the critical ischemic period and afterward. The boundary allows the fabrication and clinical use of implant assemblies and methodologies that can carry enough cells to be of therapeutic value to the host, yet occupy a relatively small, compact area within the host.

Angiogenic tissue implant systems and methods

A method to prevent or treat cancer in a patient comprising: administering a first set of tumor cells; where at least some of the first tumor cells have at least one tumor antigen corresponding to antigen of the patient's tumor cells; where the tumor cells are contained in an implantable chamber; the chamber defined by a wall including a porous boundary between the patient's immune cells and the contained cells and pervious to subcellular antigenic material; where the boundary prevents contact between patient immune cells and the contained tumor cells, and where the boundary permits subcellular antigenic materials to exit the chamber; and rendering a second set of tumor cells nontumorigenic; where at least some of the second tumor cells have at least one tumor antigen corresponding to antigen of the patient's tumor cells; administering the second tumor cells to the patient without containing them in a chamber.

The coating of a RF active material on a non-RF active substrate material of typical thickness for packaging purposes, can generate sufficient thermal energy to effect strong bonding of the substrate materials. The RF active material may be-deposited on less than the entire inner surface area of the substrate material, preferably, at or near the portion of the substrate surface which represents the heat seal interface. In this manner of application, additional coating or printing of other substances on the substrate surface can be achieved without hampering the heat sealing process. Flexible medical containers capable of containing a product which is maintained and removed under sterile conditions, can be constructed on commercial production machines from these coated non-RF active substrate materials.

A sterilizable, plastic medical container has a body section formed of thin, multi layer film. The film has a first layer formed of cross-linkable plastic free or essentially free of extractable plasticizers, such as poly(ethylene vinyl acetate), and a second layer formed of a substantially non-cross-linkable plastic having a higher melting temperature than the first layer, such as high density polyethylene. The first layer is inwardly oriented in contact with the contents of the container. A port formed of the same plastic can be heat sealed to the body section. The container is irradiated to effect cross-linking, filled with fluid, and the port sealed. The fluid filled container can then be heat or steam sterilized.
