DESCRIPTION

The Medtronic MiniMed 670G System is the first FDA approved hybrid closed loop system that monitors glucose and automatically adjusts the delivery of long acting or basal insulin.

The Medtronic MiniMed 670G System consists of a continuous glucose monitor (CGM) that measures the user's glucose levels for up to seven days, an insulin pump that delivers insulin to the user, and a glucose meter used to calibrate the CGM.

The MiniMed 670G System is able to decrease or stop insulin delivery when it detects the user's glucose is low, or increase the insulin delivery when the system detects the user's glucose levels are high with no input from the user. The glucose sensor contains a wire that is inserted under the skin on the abdomen and measures glucose values in the tissue fluid. The glucose values are wirelessly sent to the insulin pump, and displayed along with glucose trend information, alerts, and alarms on the pump screen. The insulin pump delivers a prescribed dosage of insulin through an infusion set. The insulin pump can automatically adjust the delivery of insulin using a mathematical equation, or algorithm that incorporates information from the CGM.

The system has two modes; Manual Mode and Auto Mode. While in Manual Mode, the system can be programmed by the user to deliver basal insulin at a preprogrammed constant rate. The system will automatically suspend delivery of insulin if the sensor glucose value falls below or is predicted to fall below a predetermined threshold. The system will also automatically resume delivery of insulin once sensor glucose values rise above or are predicted to rise above a predetermined threshold. While in Auto Mode, the system can automatically adjust basal insulin by continuously increasing, decreasing, or suspending delivery of insulin based on CGM values (different from Manual Mode where basal insulin is delivered at a constant rate). Although Auto Mode can automatically adjust basal insulin delivery without input from the user, the user must still manually deliver insulin therapy during meals.
