 At the end of the final basal infusion period, the infusion set tubing will be clamped to mimic an occlusion event and allowed to run until either an occlusion alert no delivery is signaled by the pump, or a minimum of 30 minutes, whichever comes first. Infusion pressure data will be collected during the entire infusion period, including the time the tubing is clamped. After removal of the device from the body, the presence of fluid on the application site skin Leakage will be determined by visual assessment then measured using gravimetric analysis, if applicable.
