Guardian Connect
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 Guardian Connect is a continuous glucose monitoring (CGM) system that provides real-time glucose data on a compatible smartphone. The system offers optional low and high blood sugar notifications and can be inserted on the abdomen or back of the upper arm.
MARD of 9.6%
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.
Receiver
Trends and alerts are viewed directly on a mobile device. Available for both iOS and Android devices.
Transmitter
Seashell-shaped with built-in Bluetooth capability that allows it to send glucose data directly to a smartphone every 5 minutes.
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm. Push buttons applicator allows sensor to be placed on the body in one step.
Device Details
Overview
Compact all-in-one sensor sensor, made by Abbott, exclusively designed for MiniMed 780G system.
One of the larger sensors, may be cumbersome to wear on some parts of the body under clothes.
Affordability and Access
$$$$
Coverage will depend on insurance policies and Medtronic’s rollout plan
$$$$
Sometimes covered. The costs vary depending on individual insurance coverage and how insurance classifies CGMs. Price range $0-$600/month.
Data Monitoring Options
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Yes
CGM data can be linked to a CareLink account and shared with the user's health care team.
Data View Options
Yes
Data view directly on your connected pump or smart device.
Yes
The Guardian Connect mobile app allows users to view glucose levels, trends, create customizable alerts, and share blood glucose data with family and friends.
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 Days
Sensors last 7 days, and transmitter battery needs weekly charging and replacement once a year. Both can be stored between 36°F - 86°F.

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).
Waterproof transmitter when submerged in up to 2.5 meters of water for 30 minutes and must be within 20 feet of a connected mobile device.
Avoiding Highs and Lows
Continuous closed-loop insulin adjustment helps maintain tighter control.
Measures sensor glucose 24/7 and sends alerts when a high or low is detected. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Small & Discreet. Very small, discreet form factor, and minimal bulk.
More tape is needed for Medtronic sensors.
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.
Sensor trends can be used for dose adjustment.
Easy to Use
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Rechargeable sensor transmitter but has the most steps to change sensor.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
2 daily finger-sticks are needed to calibrate the sensor.
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 discreet. Ability to see sugar on watch or phone. Sensor requires regular meter use.
