The MiniMed 770G is the first-of-its-kind system that can automatically adjust insulin delivery based on continuous glucose monitor values for for such young children, according to the agency. The FDA approved an earlier MiniMed model, the 670G system, for people aged 7 to 13 with Type I diabetes in 2018.
MiniMed 770G System is a Bluetooth-enabled version of the 670G, with other modifications. It works by measuring glucose levels in the body every 5 minutes and automatically adjusting insulin delivery by either administering or withholding insulin. The system includes: a sensor that attaches to the body to measure glucose levels under the skin; an insulin pump strapped to the body; and an infusion patch connected to the pump with a catheter that delivers insulin. While the device automatically adjusts insulin levels, users need to manually request insulin doses to counter carbohydrate consumption at mealtime.
