Abstract: An implantable device for the prevention or treatment of cancer comprising an implantable chamber containing tumor cells, or somatic cells engineered to express at least one antigen corresponding to antigen of a patient's tumor; the chamber having a porous wall to provide, in use, a porous boundary between the patient's immune cells and the contained cells; the porosity of the boundary being sufficient to permit subcellular antigenic material to pass through the boundary, while preventing the contained cells and patient immune cells from passing through the boundary.

Abstract: 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.
