| 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. |
