Dexcom G7
Instinct sensor, made by Abbott, for MiniMed 780G
Summary
Dexcom G7 is a low-profile, all-in-one glucose sensor/transmitter and warms up faster than other CGMs on the market. This sensor lasts for 10 days and sends real-time glucose readings to a compatible smartphone app or directly on an Apple Watch. No finger pricks or scanning is needed. Optional low and high-blood sugar notifications are available for this system.
FDA-approved for wear on the back of the upper arm for ages 2 years and older or the upper buttocks for ages 2-17.
MARD of 8.2%
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%
Components
Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every 5-minutes. Push-button applicator allows sensor to be placed on the body in one step.
Receiver
Conveniently access glucose readings using a reader, smartphone, or directly on an Apple Watch. Phone app available for both iOS and Android devices.
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.

Coverage will depend on insurance policies and Medtronic’s rollout plan
Data Monitoring Options
Yes
Automatically and continuously sends data to the user’s Dexcom Clarity web-based cloud which is accessible by clinicians.
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Data View Options
Yes
Users must download the Dexcom G7 and Dexcom Clarity apps to view and share data. Both apps provide multiple data views, sharing options, and access through the clinician portal using a code from the user's device. Caregivers can use the Dexcom Follow app to view data.
Yes
Data view directly on your connected pump or smart device.
Duration and Storage
10 Days
Sensors last 10 days. They are shipped 3 boxes at a time every 3 months – 9 sensors. Works at 50ºF – 108ºF
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.

Patient Considerations
Active Lifestyle
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
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).
Avoiding Highs and Lows
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Continuous closed-loop insulin adjustment helps maintain tighter control.
Comfort
Low profile and low maintenance sensor application.
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Easy Insulin Dosing
Real-time data and alerts make dose adjustment easier.
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.
Easy to Use
No scanning required. Readings are sent directly to the mobile app every 5 minutes.
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.

Privacy
Quiet Mode (Vibrate). All system alerts will vibrate when this setting is enabled. Urgent Low Soon and technical alerts will sound if not acknowledged.
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.
