Frequently asked questions

What is the MiniMed Flex system?

Add icon collapse icon

The MiniMed Flex system is MiniMed’s latest automated insulin delivery system. It includes a small, screenless insulin pump, SmartGuardTM advanced hybrid closed loop technology, a compatible CGM sensor and infusion set, and the MiniMed™ app so you can control your pump from your compatible device.

Is MiniMed Flex a fully automated insulin delivery system?

Add icon collapse icon

MiniMed Flex is an automated insulin delivery system that automatically adjusts basal insulin and delivers correction boluses up to every 5 minutes when being used in SmartGuardTM mode. You only need to let the system know when you are eating by bolusing for meals.

How is the MiniMed Flex pump different from the MiniMed 780G pump?

Add icon collapse icon

While both pumps use the same SmartGuardTM automation, MiniMed Flex is a smaller, screenless pump that can be controlled through a compatible device and has a rechargeable battery.

Which CGM sensors and infusion sets work with MiniMed Flex pump?

Add icon collapse icon

MiniMed Flex is cleared to work with the Simplera SyncTM sensor and all of our infusion set options, including the 7-day ExtendedTM infusion set. We are working on making the pump work with the other sensor options that we offer and will share timelines as soon as we can.

How much insulin does MiniMed Flex hold?

Add icon collapse icon

MiniMed Flex reservoir holds 300 units of insulin.

How do I use the MiniMed Flex pump without a screen?

Add icon collapse icon

The MiniMed Flex pump is designed so you don't need a screen. Instead you will use the MiniMed app on your compatible device to view your data and make changes, while the pump will still keep you informed with lights, sounds, and buttons.

How long does the MiniMed Flex pump battery last?

Add icon collapse icon

The pump is charged using a dedicated charging base with a USB-C cable and wall plug, which is included in the pump kit. You can stay connected or disconnect the pump from your body while charging. It’ll take approximately 30 minutes to complete a full charge which should last about 7 days.



You can charge the pump as often as you’d like. Regular charging helps ensure consistent performance.

Is Flex pump waterproof?

Add icon collapse icon

The MiniMed Flex pump is waterproof up to 8 feet for 1 hour and 45 minutes (105 minutes).

Where do users view alerts and alarms for the MiniMed FlexTM system?

Add icon collapse icon

You’ll get alerts through lights and sounds on the pump and on the MiniMedTM app. The app shows you full alert details and lets you take action, if needed.

Can users deliver meal or correction boluses from the MiniMed™ app?

Add icon collapse icon

Yes. You can deliver meal and correction boluses from the MiniMedTM app (and without taking out your pump).

Can I get the MiniMed Flex if I do not have a compatible smartphone?

Add icon collapse icon

If you don’t have a compatible device, you can purchase App Manager to use the MiniMed Flex System. The App Manager is device that comes with the MiniMedTM app preinstalled and is intended only for managing your diabetes therapy with MiniMedTM systems.

How will the Flex system handle a lost/damaged/out of power phone to continue treatment?

Add icon collapse icon

If the pump loses connection to the MiniMed app for whatever reason, it’ll continue to deliver insulin based on what is programmed through the app. Meaning, if you’re in SmartGuardTM mode, it’ll continue to use the SmartGuardTM algorithm, as long as the sensor is still connected to the pump. However, you will need to connect back to the app in order to give a bolus or clear alerts. 



It is always recommended to have a back-up plan in place should something happen to your pump or MiniMed app.

What happens if my phone is out of WiFi or cellular range?

Add icon collapse icon

Your pump and app talk to each other through Bluetooth and not through WiFi or a cellular connection. As long as your Bluetooth is on, including when in Airplane Mode, your pump and app can continue to communicate.

You will need WiFi or a cellular connection to update the app or complete a pump software update.

How close does the app need to be to the pump to not lose connection?

Add icon collapse icon

The pump, sensor and mobile device should stay within 10 feet of each other to help prevent losing connection. The app should always be kept open on your phone and can be run in the background.

Will the holster for the MiniMed 780G system work with the Flex pump?

Add icon collapse icon

No, the pumps have different dimensions.

Will cases and clips be available for the Flex pump?

Add icon collapse icon

Yes, every pump will come with a with a gray clip. Other colors will be available for purchase. The cost of a clip is $24.99.

Important Safety Information: MiniMed FlexTM system with SmartGuardTM technology with Simplera SyncTM sensor

The MiniMed FlexTM system is intended for the continuous delivery of basal insulin at selectable rates, and the administration of insulin boluses at selectable rates for the management of type 1 diabetes mellitus in persons 7 years of age and older, and of type 2 diabetes mellitus in persons 18 years of age and older requiring insulin. The system is also intended to continuously monitor glucose values in the fluid under the skin. The MiniMed FlexTM system includes SmartGuardTM technology, which can be programmed to automatically adjust insulin delivery based on continuous glucose monitoring (CGM) sensor glucose values and can suspend delivery of insulin when the SG value falls below or is predicted to fall below predefined threshold values.

The Simplera SyncTM sensor can be used one time and has a life up to 6 days, followed by a grace period of 24 hours. During the grace period, the sensor will continue to work as it did during the first 6 days, to allow the patient to change their sensor more flexibly. However, some sensors may not survive the full wear period for a variety of reasons. Please be prepared to replace the sensor during the grace period to ensure sensor glucose values continue to be monitored.

The Simplera SyncTM sensor is not intended to be used directly to make therapy adjustments while the MiniMed FlexTM system is operating in manual mode. All therapy adjustments in Manual mode should be based on measurements obtained using a blood glucose meter and not on values provided by the Simplera SyncTM sensor. The Simplera SyncTM sensor has been studied and is approved for use in patients ages 7 years and older and in the arm insertion site only. Do not use the Simplera SyncTM sensor in the abdomen or other body sites, including the buttocks, due to unknown or different performance that could result in hypoglycemia or hyperglycemia.

The Medtronic MiniMed FlexTM System consists of the following devices: MiniMed FlexTM Insulin Pump and the Simplera SyncTM sensor. The system requires a prescription from a healthcare professional.

WARNING: Do not use the SmartGuardTM feature for people who require less than 8 units or more than 250 units of total daily insulin per day. A total daily dose of at least 8 units, but no more than 250 units, is required to operate in the SmartGuardTM feature.  

WARNING: Do not use the MiniMed FlexTM system until appropriate training has been received from a healthcare professional. Training is essential to ensure the safe use of the MiniMed FlexTM system.

WARNING: Do not use SG values to make treatment decisions, including delivering a bolus, while the pump is in Manual Mode. When the SmartGuardTM feature is active and you are no longer in Manual Mode, the pump uses an SG value, when available, to calculate a bolus amount. However, if your symptoms do not match the SG value, use a blood glucose (BG) meter to confirm the SG value. Failure to confirm glucose levels when your symptoms do not match the SG value can result in the infusion of too much or too little insulin, which may cause hypoglycemia or hyperglycemia.

Pump therapy is not recommended for people whose vision or hearing does not allow for the recognition of pump signals, alerts, or alarms. The safety of the MiniMed FlexTM system has not been studied in pregnant women or in persons using other anti-hyperglycemic therapies that do not include insulin. For complete details of the system, including user guides and important safety information such as indications, contraindications, warnings and precautions associated with system and its components, see https://bit.ly/MiniMedRisks.
