Medtronic’s Guardian Connect CGM + Limited Availability


Look out—there’s a new CGM in town!

In March of this year, the FDA approved Medtronic’s Guardian Connect mobile Continuous Glucose Monitor (CGM). Also approved was the Guardian Connect App which pairs to the CGM, and is compatible with Apple iOS devices. Medtronic’s Guardian Connect mobile system will begin a “soft” launch during this month through July with a wider release in the fall.

The system has been available outside of the US since 2016.

Similar to the other Continuous Glucose Monitors on the market today, the Guardian Connect can be worn on the arm or the abdomen. The sensor can last for up to one week, and it requires a two-hour calibration period. Manual blood sugar checks (fingersticks) are required for occasional calibrations.

What separates the Guardian Connect from the other CGM systems such as the Dexcom and Freestyle Libre, is the system’s lack of receiver. Blood Glucose graphs are sent directly to your iOS device. Medtronic’s new system is considered a “standalone” CGM, as it does not send data to a paired insulin pump.

The Medtronic MiniMed 670G pump does use the same sensor as the new CGM, however, a Bluetooth feature has not been established yet for the pump.
