Medtronic InPen
Instinct sensor, made by Abbott, for MiniMed 780G
Summary
The InPen system enhances management with multiple daily injections because it tracks data in real-time and offers personalized dosing recommendations. This system combines the Guardian Connect CGM with smart insulin pens for more time in range.
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
Controller
Inpen connects to a mobile app and displays dosage information directly on a smart mobile device.
Cartridge
InPen is compatible with Humalog, Novolog, and Fiasp U-100 3.0 mL insulin cartridges.
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm. InPen is compatible with the Medtronic Guardian Connect sensor (left) or the Dexcom G6 sensor (right).
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.

Duration and Storage
12-month pen 7-day sensor
Sensor lasts for 7 days, insulin pen lasts for up to 12 months with refillable cartridges, transmitter is rechargeable. Sensor can be stored between 36°F - 86°F and pens can be kept at room temperature.
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
Light on body. Pens are easy to use and do not remain attached to the body, sensor 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
Limited customizability. System integrates the Guardian Connect CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Continuous closed-loop insulin adjustment helps maintain tighter control.
Comfort
Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors.
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Easy Insulin Dosing
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
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
Simple design. Replaces regular insulin pen. No additional devices to add on.
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
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.
