Medtronic Simplera Sync
Tempo Pen
Summary
This is a disposable, all-in-one CGM sensor integrated with Medtronic’s pump systems (e.g., MiniMed 780G). Typical wear time is 6 days, plus a 24-hour “grace period.” No routine fingersticks are required when the device is in closed-loop/SmartGuard mode.
FDA approved for ages 7+ on the back of the upper arm
MARD of ~9%
The Tempo system enhances management with multiple daily injections because it tracks data in real-time and offers personalized dosing recommendations. This system combines the Dexcom G6/G7 CGM with smart insulin pens for more time in range.
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
Smart button and sensor readings displays dosage information directly on smart mobile device.
Controller
Smart button records daily injections and sends them to the compatible app.
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.

Duration and Storage
6 Days
Sensors last 6 days, with a 24-hour grace period, and need about 2 hours to warm up. They work between 41°F – 104°F and should be stored between 36°F – 86°F. They are usually shipped in 1–3 month supplies, which is about 5–15 sensors at a time.
8-month button 10-day sensor
Sensor lasts for 10 days, pen button lasts for up to 8 months. Sensors can be stored between 36°F - 86°F, and pens can be kept at room temperature.

Patient Considerations
Active Lifestyle
Compact and integrated. Reducing bulk; compatibility with daily activities depends on the adhesive and body movement. Water-resistant up to 8 feet (2.4 m) for 30 minutes.
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
Avoiding Highs and Lows
SmartGuard closed-loop. Pump adjustments use sensor data continuously to reduce highs and lows.
Limited customizability. System integrates the Dexcom G6/G7 CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Low profile. No overtape needed and one-hand insertion.
Many components. Have to carry pens and pen needles. CGM is attached to the body.
Easy Insulin Dosing
SmartGuard technology. When paired with the MiniMed 780G, it automatically adjusts basal and gives correction boluses based on sensor readings. In manual mode, glucose values can guide dosing decisions, but fingersticks are required for confirmation.
Dosing recommendations. Displays personalized mealtime dosing recommendations.
Easy to Use
All-in-one. Eliminates the need for a separate transmitter, simplifying sensor changes (although more frequent due to the 6-day wear).
Simple design. Replaces regular insulin pen. No additional devices to add on.
Fewer Fingersticks
Calibration is optional. Perfect if you like having that choice.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Small and integrated, but visible on the back of the arm. No separate transmitter reduces the number of visible parts. Alerts and alarms can be adjusted for discretion.
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
