Summary

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.

The FreeStyle Libre 2 is the thinnest, all-in-one glucose sensor/transmitter and requires scanning using a handheld reader or compatible smartphone with an app. This sensor lasts for 14 days and only needs fingersticks as backup. Optional low and high blood sugar notifications are available for this system. 

FDA approved for insertion on the back of the upper arm (ages 4 years and older).

Medtronic 780G : Sensor

Sensor is inserted underneath the skin, either on the abdomen or arm.

Medtronic 780G : Controller

Medtronic 780G : Controller

Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones.

Medtronic 780G : Infusion Set

Medtronic 780G : Infusion Set

An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.

Freestyle Libre 2 : Sensor

Freestyle Libre 2 : Sensor

Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every minute. Push-button applicator allows sensor to be placed on the body in one step.

Freestyle Libre 2 : Receiver

Freestyle Libre 2 : Receiver

Conveniently access glucose readings using a reader, smartphone, or both. Available for both iOS and Android devices.

Device Details

All-in-one glucose sensor/transmitter with low and high blood glucose alarms can be worn on the upper arm.

Affordability and Access

$$$$
Coverage information is not yet available. Price range; $0-10,769 to start and $0-$300/Month. Price range varies depending on insurance coverage. 

 

$$$$
Widely covered. Provided by pharmacies. Price range; $0-$100/month. Often the cheapest and easier to access sensor. 

Data Monitoring Options

Yes
CareLink connect is available for care partners with up to five people who can follow a pump user and receive high and low notifications to help keep everyone in the loop.

Yes
After each sensor scan with the mobile app or reader, data is automatically sent to the user’s LibreView account which enables sharing with HCPs and caregivers via the LibreLinkUp app. Data upload is possible with Glooko and Tidepool data-management systems.

Data View Options

Yes
Data is viewed on compatible smart devices through the MiniMed Mobile App. You can download and view pump or CGM data on CareLink.

Yes
Freestyle Libre 2 app provides glucose readings and alarms, multiple data views, the ability to share glucose data and real-time alarms with LibreLinkUp, and the ability to connect to a clinician's practice through LibreView. 

Duration and Storage

7-day pump 7-day sensor
Sensors last 7 days, transmitter needs weekly charging, store between 36 °F - 86 °F. Pump can be used for up to 7 days with the extended infusion set and works between 40ºF - 104ºF. 

14 Days
Sensors last 14 days and work between 50ºF - 113ºF. They are shipped in orders of 1-3 months at a time - which is 2-6 boxes at a time.

Patient Considerations

Active Lifestyle

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.

Water-resistant for up to 3 feet deep for 30 minutes and light on the body, does not get in the way of activity. The reader must be within 1.5 inches of the sensor to scan it. 

Avoiding Highs and Lows

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.

Optional glucose alerts for low and high glucose levels. Trend arrows show the direction glucose is heading, with the rate of change. 

Comfort

Somewhat comfortable. Medtronic sensors need more tape than other sensors. Largest pump option. 

Low profile sensor and small adhesive.

Easy Insulin Dosing

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. 

Scanned sensor trends can be used for dose adjustment.

Easy to Use

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.

Requires scanning. Self-application and manual scanning are required. Easy self-application.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Factory-calibrated sensor. Finger-sticks needed for backup only. 

Privacy

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. 

Hypoglycemia safety alarm. Discreet size but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
