Instinct sensor, made by Abbott, for MiniMed 780G
Minimed 780G with Smart Guard
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%
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
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.
Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Controller
Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones.
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm.
Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.

Data Monitoring Options
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
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 view directly on your connected pump or smart device.
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
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.
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
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).
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
Continuous closed-loop insulin adjustment helps maintain tighter control.
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
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Somewhat comfortable. Medtronic sensors need more tape than other sensors. Largest pump option.
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.
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
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
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. 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.
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.
