Instinct sensor, made by Abbott, for MiniMed 780G
Tidepool Loop
Summary
This is a CGM sensor made by Abbott, exclusively designed for MiniMed 780G system. It will work with MiniMed 780G and related systems. Wear time is up to 15 days, and warm-up is ~1 hour. Fingersticks are not required in closed-loop mode.
FDA approved for ages 7+ for use on the upper arm (back of upper arm)
MARD of ~8.5%
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.
Components
Sensor
Sensor uses a thin, flexible filament beneath the skin to continuously measure glucose every 5 minutes. Simple, one-step applicator makes insertion fast and easy.
Controller
Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via insulin pump.

Duration and Storage
15 Days
Sensors last up to 15 days and need about 1 hour to warm up. They work between 50ºF – 113ºF and should be stored between 36ºF – 82ºF. They are usually shipped in 1–3 month supplies, which is about 2–6 sensors at a time.
Pump and CGM information not yet available.

Patient Considerations
Active Lifestyle
Long wear & water resistant. Longer wear reduces change burden; sensor design aims for robustness with movement. Water-resistant up to 3 feet (1 m) for 30 minutes (same standard as FreeStyle Libre family).
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
Continuous closed-loop insulin adjustment helps maintain tighter control.
Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.
Comfort
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Low-profile mobile app. Dosing and other adjustments can be done directly on the mobile app.
Easy Insulin Dosing
MiniMed 780G closed-loop algorithm: adjusts basal and delivers automatic correction boluses using sensor data. Longer wear (15 days) means fewer interruptions in automated dosing. In manual mode, it still requires fingerstick confirmation before dosing from sensor values.
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
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Easy dosing. Software makes most dosing decisions easy to do on the fly.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Small & Customizable. Extremely small (about the size of two stacked pennies), designed to be less noticeable under clothing. Upper arm site only; discreet but still visible with sleeveless clothing. Alerts can be customized on the connected pump for quieter use.
Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available.
