FDA has approved a Medtronic PMA supplement for a new arm indication for the Guardian Sensor 3 glucose monitor that will enable patients to wear the sensor on the upper arm. The company says this is the only sensor FDA approved to control automated insulin delivery via a hybrid closed loop system —- the MiniMed 670G system. The device features the company’s most advanced SmartGuard algorithm, which helps to increase “time-in-range by automatically adjusting basal insulin delivery every five minutes based on real-time data,” it says.
