History

Historical Context

In September 2016, the FDA approved the Medtronic MiniMed 670G, the first hybrid closed-loop insulin delivery system, enhancing diabetes management. This technology integrates a continuous glucose monitor and insulin pump, automatically adjusting insulin delivery based on blood glucose levels.
