Summary
This system is the first automated insulin delivery system that combines the Tandem t:slim x2 with the Freestyle Libre 2 Plus continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends. It's easy to use and allows bolus dosing directly from a compatible iOS or Android smartphone.
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
Control IQ with Freestyle Libre : Pump
Touch screen pump connects tubing to a small patch called an infusion set that attaches to the body.
Control IQ with Freestyle Libre : Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
Control IQ with Freestyle Libre : Controller
t:slim pump receives CGM readings to automatically adjust basal insulin delivery via an infusion set. Compatible smartphone can be used to view and control insulin delivery using the t:connect app.
Control IQ with Freestyle Libre : Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Abbott/Medtronic Instinct Sensor : 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.
Device Details
Overview
This system automatically adjusts insulin levels from the Tandem t:slim X2 pump based on the Libre 2 Plus readings for more time in range.
Compact all-in-one sensor sensor, made by Abbott, exclusively designed for MiniMed 780G system.
Affordability and Access
$$$$
Widely covered for insulin-dependent type 1 and 2. Supplies for Pump and Sensor provided by DME suppliers. Price range; $5-$6,995 to start and $0-$200/month.
$$$$
Coverage will depend on insurance policies and Medtronic’s rollout plan
Data Monitoring Options
Yes
The t:connect mobile app for the t:slim X2 pump wirelessly uploads pump and CGM data to the cloud-based t:connect web application.
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Data View Options
Yes
Data can be viewed directly on the pump screen or on the t:connect mobile app (available for both iOS and Android devices).
Yes
Data view directly on your connected pump or smart device.
Duration and Storage
3-day pump 15-day sensor
Sensors last 14 days, and transmitters last 90 and work at 50ºF - 113ºF. Pump can be used for up to 72 hrs, battery life lasts five days with the use of CGM, and work between 40°F - 99°F.
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
Exercise Activity. Can manually increase target range to 140-160 mg/dl. Insulin decreases when Control IQ predicts CGM ≤140 mg/dl and increases when ≥ 160 mg/dl within 30 minutes. Autocorrections will still occur. Pump is not waterproof. CGM is waterproof.
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
Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a target blood glucose of 110 mg/dl. Auto-bolus is available once per hour to correct blood sugar above 180 mg/dl.
Continuous closed-loop insulin adjustment helps maintain tighter control.
Comfort
Low profile. Low profile/low maintenance sensor. Small tubed pump with the most infusion sets to pick from.
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Easy Insulin Dosing
Automatically adjusts dosing. Sensor integration allows for the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Basal in 0.001 increments, bolus in 0.01 increments. Extended bolus available.
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
Modern & no scanning required. Rechargeable and touchscreen pump. Sensor does not require scanning and sends minute-by-minute readings directly to the pump.
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed. CGM has a built-in hypoglycemia safety alarm that alerts users when glucose is below 55 mg/dl and is always on.
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.
