A Schematic of the graft fabrication layers. B Polyimide 16 gold electrode array. Panel C Expanded view of the sensing array (×10). D Electrode array in situ, illuminated intraluminally to highlight the sensor and sensing apertures. E Full-length array highlighting proximal sensor and distal connection to telemetry. F A prototype device with intraluminal circumferential sensor apertures on a single plane on the inside of the graft and the sensor held in place with clear heat PTFE shrink. G Prototype device attached to wireless impedance electronics (highlighted green) power source (highlighted gold), magnetic reed switch as used for in vivo studies.
