Medtronic’s hybrid closed-loop system, the world’s first “artificial pancreas,” is hitting the U.S. market. The system is the only FDA-approved insulin pump that automatically delivers basal insulin to control blood glucose levels in people with Type 1 diabetes.

The system includes a glucose sensor which measures glucose levels in the fluid just under the skin, the MiniMed 670G insulin pump and an infusion patch, which delivers insulin through a catheter. It uses an algorithm to self-adjust the delivery of basal, or background, insulin every five minutes based on real-time data gathered from the sensor.
