Indications for Use

The MiniMed Go app is indicated for people with diabetes or their caregivers. The indicated patient population varies based on the combination of connected CGM and injector. Simplera sensor only: Diabetes patients ages 18 years and older InPen smart insulin pen only: Diabetes patients ages 7 years and older, or younger patients under the supervision of an adult caregiver Simplera sensor and InPen smart insulin pen: Diabetes patients ages 18 years and older Instinct sensor and InPen smart insulin pen: Diabetes patients ages 7 years and older, or patients ages 2 to 6 years under the supervision of an adult caregiver The dose calculator of the MiniMed Go app is indicated for the management of diabetes by people with diabetes for calculating an insulin dose based on user entered data, most recent glucose value and active insulin. To calculate a recommended insulin dose, a healthcare professional must provide patient-specific therapy settings including glucose target, insulin-to-carbohydrate ratio, and insulin sensitivity parameters to be programmed into the software prior to use. For an insulin dose based on fixed or variable meal sizes, a healthcare professional must also provide patient-specific fixed doses or meal sizes to be programmed into the software prior to use. When connected to a CGM, the app supports display of Sensor Glucose (SG) values and trend arrows. When connected to the InPen smart insulin pen, the app supports automatic logging of insulin doses, tracking of active insulin, and a dose calculator. The app also supports alerts or reminders for low glucose, high glucose, and insulin doses.

Device Story

Software-only mobile application for diabetes management; connects via Bluetooth/NFC to compatible CGMs (Simplera, Instinct) and InPen smart insulin injector. Consolidates data visualization, insulin dose calculation, and event logging. Input: user-entered glucose/meal data, real-time CGM sensor glucose (SG) values, and insulin delivery logs from InPen. Operation: calculates insulin doses based on HCP-programmed therapy settings (glucose target, insulin-to-carbohydrate ratio, insulin sensitivity) and active insulin tracking to prevent stacking. Output: recommended insulin doses, SG trends, and alerts (high/low glucose, missed doses). Used in home environments by patients or caregivers. App serves as primary display/control interface; replaces standalone CGM apps. Benefits: unified platform for therapy management, improved user experience, and automated logging of insulin doses.

Clinical Evidence

No clinical data. Human factors validation studies conducted with 50 participants (17 Type 1 adults, 16 Type 2 adults, 17 pediatric) demonstrated that intended users can safely and effectively perform critical tasks without use-related errors.

Instinct sensor and InPen smart insulin pen: Diabetes patients ages 7 years and older, or patients ages 2 to 6 years under the supervision of an adult caregiver

The dose calculator of the MiniMed Go app is indicated for the management of diabetes by people with diabetes for calculating an insulin dose based on user entered data, most recent glucose value and active insulin.

To calculate a recommended insulin dose, a healthcare professional must provide patient-specific therapy settings including glucose target, insulin-to-carbohydrate ratio, and insulin sensitivity parameters to be programmed into the software prior to use.

For an insulin dose based on fixed or variable meal sizes, a healthcare professional must also provide patient-specific fixed doses or meal sizes to be programmed into the software prior to use.

When connected to a CGM, the app supports display of Sensor Glucose (SG) values and trend arrows. When connected to the InPen smart insulin pen, the app supports automatic logging of insulin doses, tracking of active insulin, and a dose calculator. The app also supports alerts or reminders for low glucose, high glucose, and insulin doses.

## C Special Conditions for Use Statement(s):

Rx - For Prescription Use Only.

- Follow the instructions and safety warnings in this user guide to receive alerts. Missing alerts from the app can result in undetected low and high glucose levels.
- Always use a BG meter reading to make treatment decisions if no sensor data are available or if symptoms do not match the SG value.
- Do not use the app if you have insufficient vision or hearing as you will need to verify alerts sent by the app.
- Do not use the app without understanding how the mobile device settings work. If any settings are changed, the app display and notification features may not work as intended, including not receiving SG alerts or status alerts.
- Make sure that your settings in the app are correct. Your healthcare professional should provide your therapy settings. Incorrect settings may result in incorrect recommendations which may result in hypoglycemia or hyperglycemia.
- Make sure Bluetooth is on, even if the mobile device is in airplane mode. If Bluetooth is off, the app will not send SG information or alerts.
- Do not force close the app. If the app is closed, the app will not send SG information or alerts.
- Check the app occasionally to make sure it is running. The mobile device may close the app automatically when another app is in use, such as a game. If the app is closed, the app will not send SG alerts.
- Always make sure to open the app after the mobile device restarts to ensure the app sends SG alerts.
- Turning off automatic updates on the mobile device may help to avoid unintentionally updating to an operating system that is not confirmed as compatible with the app.

- When power saving settings are enabled, the mobile device may delay the alerts and notifications from the app.
- Alerts for the app will sound through headphones when headphones are connected. If headphones are connected but they are not being used, SG alerts may not be heard.
- Always allow notifications for the app. If notifications are turned off, the app will not send any alerts, including the Urgent Low Alert.
- If alerts and reminders are disabled on the mobile device, you will not receive them, including the Urgent Low Alert.

## III Device Description

The MiniMed Go App is a software-only mobile application intended to connect with compatible Continuous Glucose Monitors (CGMs) – including the Simplera Sensor (P160007/S047) and Instinct Sensor (K233537), and the InPen smart insulin injector (K242775). The App enables people with diabetes to manage their therapy through data visualization, insulin dose calculation, and event logging. The App can be installed on compatible mobile devices, enabling users to effectively manage their diabetes. The compatible devices include the user’s Android/iOS mobile phones or the App Manager, a compatible display device configured to host Medtronic MiniMed applications.

The App Manager is a compatible display device configured to host Medtronic MiniMed applications. It can be used as an alternative to installation of MiniMed Go App on the user’s personal compatible smartphone. The App Manager is a durable handheld medical device consisting of commercial off-the-shelf (COTS) Samsung smartphone hardware, with a Medtronic branded case, operating on the Android OS with MiniMed Go App pre-installed and configured for diabetes management use only. The App Manager is configured via a Mobile Device Management (MDM) service to lock down specified functionalities and to ensure that the App Manager is used solely as a medical device.

The App Manager is used in conjunction with the MiniMed Go App to facilitate communication with the InPen, Simplera sensor and Instinct sensor via COTS Samsung device’s BLE and NFC connectivity. Its Wi-Fi connectivity is used to upload data to CareLink Cloud.

The App functions as the primary display and control interface for the InPen and connected CGM systems, consolidating device management, data visualization, and alert functions within a single software platform. It replaces the standalone CGM applications and serves as the central interface through which users manage connected devices and receive CGM, InPen and other system notifications. This integration provides a unified platform that supports diabetes therapy management and improves the overall user experience through consolidated device interaction.
