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.

Tidepool Loop is the first fully interoperable automated insulin dosing app that originated as a patient-led initiative.

Background: A diabetes non-profit called Tidepool decided in 2018 to officially support Loop and shepherd it through the FDA process. Tidepool Loop was cleared by the FDA in January 2023 with plans to launch with Dexcom and other alternate controller-enabled (ACE) pump partners (RileyLink will no longer be necessary).

2023 Updates from Tidepool:

  • Medtronic and Tidepool have decided to discontinue the development of a Medtronic insulin pump system compatible with Tidepool Loop.
  • As Omnipod 5 is now commercially available, Insulet is devoting all available resources to their Omnipod products, including the global launch and further development of Omnipod 5.
  • Future ACE Pumps that will be commercially compatible with Tidepool Loop will need to be FDA-cleared for use with third-party interoperable automated glycemic (iAGC) controllers.

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.

Automatic responses. Can set custom blood sugar targets and insulin and carb sensitivities based on type of activity. App automatically responds to blood sugar changes during activity.

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.

Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.

Comfort

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

Low-profile mobile app. Dosing and other adjustments can be done directly on the mobile app. 

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. 

Customizable. Can bolus from phone or smartwatch and all settings are expected to be customizable. More information on modifications to insulin delivery will be available soon. 

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.

Easy dosing. Software makes most dosing decisions easy to do on the fly.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Factory-calibrated sensor. Fingersticks 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. 

Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available.
