Survival of encapsulated islets: More than a membrane story

Figure 9 The design, makeup, and implantation site of the porcine-type β-Air device. A: Schematic cross section of a porcine-type β-Air device. The four dashed lines separating the central cavity from the “reduced pressure chambers” and the “reduced pressure chambers” from the islet modules are silicone rubber membranes; B: A surface image of an islet module; C: Cross section of an islet module; D: The macrochamber and connected access ports (each square is 1 cm × 1 cm); E: Illustration of the device (including the subcutaneous access ports) implanted into a mini-swine recipient; F: X-ray image of an implanted device.
