Tandem Mobi
Medtronic 780G
Summary
The Tandem Mobi is the smallest durable automated insulin delivery system available in the U.S. that can be fully controlled by a mobile device. The pump is equipped with an on-pump button for users to bolus insulin directly from the pump if they don’t want to do it from their phone. This system is combined with the Dexcom continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends.
*Compatiblilty with Dexcom G7 now available
The MiniMed 780G insulin pump operates in Manual mode when the SmartGuard feature is inactive, or the user is not wearing a compatible CGM. This pump has the ability to communicate with a Contour or AccuChek meter.
