Summary

This system combines the Tandem t:slim x2 with the Dexcom G6 or G7 continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends. It's easy to use and allows bolus dosing directly from a compatible iOS or Android smartphone. 

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.

Device Details

Overview

The system automatically adjusts insulin levels from the Tandem t:slim X2 pump based on the Dexcom G6 or G7 readings for more time in range. 

This system is integrated and has a customizable settings. Many providers are familiar with Medtronic products.

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.

Data View Options

Yes
Data can be viewed directly on the pump screen or on the t:connect mobile app (available for both iOS and Android devices).

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

Duration and Storage

3-day pump 10-day sensor
Sensors last 10 days and transmitters last 90 and work at 50ºF – 108ºF. Pump can be used for up to 72 hrs, battery life lasts five days with the use of CGM, and work between 40°F - 99°F. 

*CGM transmitter is only required for the Dexcom G6 model. 

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.

Patient Considerations

Active Lifestyle

Exercise Activity. Can manually increase target range to 140-160 mg/dl. Insulin decreases when Control IQ predicts CGM ≤140 mg/dl and increases when ≥ 160 mg/dl within 30 minutes. Autocorrections will still occur. Pump is not waterproof. CGM is waterproof. 

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 target blood glucose of 110 mg/dl. Auto-bolus is available once per hour to correct blood sugar above 180 mg/dl.

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

Low profile. Low profile/low maintenance sensor. Small tubed pump with the most infusion sets to pick from.

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

Easy Insulin Dosing

Automatically adjusts dosing. Sensor integration allows for the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Basal in 0.001 increments, bolus in 0.01 increments. Extended bolus available.

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

Modern & flexible. Rechargeable and touchscreen pump. Sensor integrated with multiple devices in case you change up what you're using. 

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.

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 placed in a pocket 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.
