FDA Approves First-of-its-Kind Automated Insulin Delivery and Monitoring System for Use in Young Pediatric Patients

The 770G System is a first-of-a-kind device for patients aged 2 to 6 years. It is the first legally marketed device that can automatically adjust insulin delivery based on continuous glucose monitor values for this patient population.

Patients with Type 1 diabetes, or their caregivers, must consistently monitor their glucose levels throughout the day and inject insulin with a syringe, pen or pump to maintain adequate glucose levels in order to avoid becoming hyperglycemic (high glucose levels) or hypoglycemic (low glucose levels).

The MiniMed 770G System, a Bluetooth-enabled version of the previously approved MiniMed 670G System (with other modifications), is a hybrid closed loop system that works by measuring glucose levels in the body every five 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.
