A new generation of CGMs

2008: Abbott launches FreeStyle Navigator CGM in the U.S.

With a sensor life of up to five days, the Navigator provided patients with blood glucose values updated once every 60 seconds.

2008: Medtronic introduces its next-generation professional CGM

Known as iPro, the physician-targeted device was smaller and lighter than preceding models.

2012: Dexcom debuts G4 Platinum

The G4 Platinum offered improved accuracy when measuring hypoglycemic blood glucose values. The device also could work for up to seven consecutive days. The device also featured a consumer-technology-influenced design. The company would expand its functionality in 2015 with the introduction of the Dexcom Share receiver that transmits G4 Platinum blood glucose data via Bluetooth to a smartphone or iPod Touch app. The functionality allows a patient to share data with up to five designated recipients. Dexcom won permission to use the device in pediatric patients in 2015.
