Components
Controller
Compatible smartphone can be used to view and control insulin delivery using the t:connect app.
Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Cartridge
Tubed insulin pumps contain a plastic reservoir that is manually filled with insulin and locked into the pump.
Pump
Touch screen pump connects tubing to a small patch called an infusion set that attaches to the body.
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
Smallest tubed pump. Modern interface resembles a smartphone but tubing may be visible.
Compact all-in-one sensor sensor, made by Abbott, exclusively designed for MiniMed 780G system.

$$$$
Coverage will depend on insurance policies and Medtronic’s rollout plan
Data Monitoring Options
Yes
Tandem t:slim mobile app wirelessly uploads cloud-based Tandem Source web application delivering access to recent patient data.
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Data View Options
Yes
Data is viewed on the pump's main screen and/or on a smartphone with the Tandem t:slim mobile app (available for both iOS and Android devices).
Yes

Duration and Storage
3 Days
Pump can be worn for up to 72 hours and works 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 mode. Optional settings for exercise to adjust treatment ranges for activity with the press of a button. Pump is not 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
Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.
Continuous closed-loop insulin adjustment helps maintain tighter control.
Comfort
Smallest tubed pump. Small patch called an infusion set consists of a complete tubing system that attaches to the body. Tubed pumps have the most infusion sets to pick from.
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Easy Insulin Dosing
Customizable dosing. Bolus calculator available to help figure out doses. Offers smallest increments of basal insulin delivery. Basal in 0.001 increments, bolus in 0.01 increments.
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
Rechargeable. Pump has a touch screen display and rechargeable battery.
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Fewer Fingersticks
Frequent finger-sticks are required.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Discreet. Smallest tubed pump with visible tubing. Ability to bolus directly on a compatible smartphone. Can be clipped to clothing or placed in a pocket to be discreet when needed. Touchscreen of pump looks like normal tech device.
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.
