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 Medtronic MiniMed™ 780G system is designed with SmartGuard™ technology, which can help with the occasionally missed meal or inexact carb counts. It provides automatic basal adjustments to manage glucose levels to a prespecified target (100 mg/dL [5.5 mmol/L], 110 mg/dL [6.1 mmol/L], or 120 mg/dL [6.7 mmol/L]) and auto correction bolus, every 5 minutes. The advanced hybrid closed-loop system uses current and past glucose trends from the Guardian™ 4 sensor to detect a rapid rise (e.g., a missed meal) in sensor glucose. No fingersticks required when the SmartGuard™ feature is active.
Components
Tandem Mobi : Pump
Small pump connects tubing to a 5 inch tubing patch called an infusion set that attaches to the body.
Tandem Mobi : Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
Tandem Mobi : Controller
Mobi pump receives CGM readings to automatically adjust basal insulin delivery via an infusion set. Compatible smartphone can be used to view and control insulin delivery.
Tandem Mobi : Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Medtronic 780G : Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.
Medtronic 780G : Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm.
Medtronic 780G : Controller
Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones.

Patient Considerations
Active Lifestyle
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Temp Target. Manually increase blood sugar target range to 150 mg/dl during activity. Temp target can run 30 minutes to 24 hours in 30-minute increments. Auto corrections are disabled. The pump is not waterproof.
Avoiding Highs and Lows
Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a set blood glucose target.
Customizable auto-bolus. Auto-correct bolus corrects highs if carb counts are miscalculated or bolus is occasionally missed. The system aims to maintain a target blood glucose level between 100 mg/dL and 120 mg/dL depending on personalized target glucose settings. Auto-bolus is available every 5 minutes to correct blood sugar between 100 mg/dL and 120 mg/dL (12 corrections per hour). Automatic insulin delivery settings are adjustable.
Comfort
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
Somewhat comfortable. Medtronic sensors need more tape than other sensors. Largest pump option.
Easy Insulin Dosing
Automatically adjusts dosing. Sensor integration allows the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Manual bolus button is available for quick dosing without a phone.
Automatically adjusts settings. Automatically adjusts insulin to reach personalized target between 100 mg/dL and 120 mg/dL. Will automatically revert to manual mode in certain situations. Basal and bolus in 0.025 increments. Extended bolus unavailable when using automated insulin delivery mode.
Easy to Use
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Easy software. Software makes many dosing decisions. Can be difficult to keep automatic insulin dosing features working. Requires fewer parts than do-it-yourself systems.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or attached to local area with an armband or adhesive sleeve to be discreet when needed. Dexcom's built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
Somewhat discrete. Ability to check blood sugar on phone or watch. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed.
