Medtronic Simplera Sync
Dexcom G6
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%
This sensor lasts for 10 days and only needs finger sticks as a backup. Dexcom G6 has 3 parts - sensor, transmitter, and receiver. Data can be viewed on a compatible mobile device or a separate receiver. Optional low and high blood sugar notifications are available for this system.
FDA approved for insertion on the abdomen (indicated for patients age 2 years and older) or the upper buttocks (ages 2-17 years).

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
Receives data automatically from the transmitter. Can be substituted by compatible smartphone and smartwatch. Available for both iOS and Android devices.
Transmitter
Sends readings from sensor to device, clips into sensor. Can be used for 90 days.
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.

Overview
Disposable, all-in-one CGM sensor integrated with Medtronic’s pump systems
Small sensor can be worn in multiple areas.
Affordability and Access
$$$$
Coverage depends on region and insurance; supplied via DME or specialty pharmacy.
$$$$
Widely covered. Provided by DME and/or Pharmacy. Price range; $0-$500/month.
Data Monitoring Options
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Yes
Automatically and continuously sends data to the user’s Dexcom Clarity web-based cloud which is accessible by clinicians. Data upload is possible with Glooko and Tidepool data-management systems.
Data View Options
Yes
Data view directly on your connected pump or smart device.
Yes
Users must download the Dexcom G6 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. Glooko and Tidepool can also be used to view data.
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.
10 Days
Sensors last 10 days, and transmitters last 90 days. They are shipped 3 boxes at a time every 3 months – 9 sensors and 1 transmitter. Works at 50ºF – 108ºF

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.
Water-resistant when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Avoiding Highs and Lows
SmartGuard closed-loop. Pump adjustments use sensor data continuously to reduce 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.
Comfort
Low profile. No overtape needed and one-hand insertion.
Low profile and low maintenance sensor application.
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.
Real-time data and alerts make dose adjustment easier.
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).
Flexible pump integration. Can be paired with multiple different types of pumps which gives flexibility for how to use the data.
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.
Hypoglycemia safety alarm. Discreet but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
