The Dexcom G7 15 Day Continuous Glucose Monitoring (CGM) System (Dexcom G7 15 Day CGM System or G7 15 Day) is an interoperable continuous glucose monitoring system intended to continuously measure the glucose in the interstitial fluid, calculate the glucose reading and make this available to the user. The Dexcom G7 15 Day CGM System is intended for single patient use at home and requires a prescription. The G7 15 Day consists of the following primary components: a wearable, consisting of a sensor and transmitter worn on the body and a display device, which can be a G7 Mobile Application (Mobile App) on an iOS or Android OS smart device or a G7 Receiver (Receiver). To achieve the intended functions and performance of the G7 15 Day, one sensor and at least one display device (App or Receiver) must be used together. The user must pair the display device(s) with each unique sensor to enable communication and start a sensor session. During an active session, the sensor reports new glucose data to the display device every 5-minutes. The display device then displays glucose data and provides alerts and information signals to the user. The reportable glucose range for the G7 15 Day is 40 mg/dL to 400 mg/Dl. Glucose values below this range are reported as 'LOW' and glucose values above this range are reported as 'HIGH'. The sensor has an expected wear period of up to 15 days with an extended 12-hour grace period after the sensor session. The grace period allows additional time for the user to change the sensor at a convenient time. The Dexcom G7 15 Day CGM System is an interoperable connected device that can communicate glucose readings and other information wirelessly and securely to and from compatible electronic interfaces via the following secure wireless connections: - Wireless communication from the transmitter directly to an interoperable device communicating through the same protocol - The Mobile App communicates to another app on a single mobile platform - The Mobile App communicates through the cloud to another software device - Dexcom Partner Web APIs: The Dexcom Partner Web APIs enable secure and reliable communication of CGM data to authorized client software intended to receive the data through the cloud. The Partner Web APIs is not intended to be used by automated insulin delivery systems (AID). Principle of Operation: The principles of operation for the Dexcom G7 15 Day CGM System remain the same as prior generations of Dexcom CGM Systems. The System uses a wire-type sensing mechanism that continuously measures interstitial glucose levels and uses a radio transmitter to wirelessly communicate glucose data to the display device for the user to see and use accordingly.

The Stelo Glucose Biosensor system (Stelo System) is an interoperable connected device that measures and displays estimated glucose values for people who are not on insulin. The Stelo System consists of the following components: the Glucose Sensing Subsystem (GSS) and the Mobile Application Subsystem (MAS). The GSS is comprised of the sensor applicator and on-body wearable, which includes a Bluetooth Low Energy (BLE) molded transmitter, adhesive patch and sensor. The sensor is a small and flexible wire, which is inserted by the applicator into subcutaneous tissue where it converts glucose into electrical current. The transmitter's onboard algorithm converts these measurements into estimated glucose values and calculates the glucose rate of change which are sent every 5 minutes to the MAS is an app that can be downloaded to a compatible smart device and that presents glucose readings and qlucose trend to the user every 15 minutes. As such, the most recent displayed glucose value might be up to 15 minutes old. Each sensor session lasts up to 15 days with an extended 12-hour grace period. The grace period allows additional time for the user to change the sensor at a convenient time. The proposed Stelo System is based on the same mode of operation and mechanism of reaction as the predicate G7 CGM System (K231081), which uses a wire type sensing mechanism that continuously measures interstitial fluid qlucose levels and a BLE enabled radio transmitter to wirelessly communicate CGM data to compatible display devices at regular 5-minute intervals. These data are also able to be reliably and securely transmitted to other digitally connected devices, excluding insulin pens and Automated Insulin Dosing (AID) systems. The Stelo System uses the same hardware design as the predicate G7 CGM System. The Stelo GSS firmware is designed to support a factory-calibrated only device (without calibration inputs), to extend the sensor wear duration from 10 to 15 days while maintaining the accuracy of the device, and to connect to authorized display devices only (i.e., Stelo MAS). The Stelo MAS includes a redesigned user interface (UI) tailored to the Stelo System's user population to simplify the use of the device. The UI includes an app onboarding specific to the Stelo MAS design and its intended use, the most recent glucose value and trend graph which are updated every 15 minutes, a narrowed glucose range display from 70 mg/dL, and an "Insights" feature providing the time in range percentage with suggestions to help users improve their time in range. The Ul does not provide any glucose or system alerts.

The G6 sensor life has an expected wear time of up to 10 days. Though the Dexcom G6 CGM System is factory calibrated and does not require user calibration, users of the Dexcom G6 CGM System have the option to calibrate the device (e.g., in situations where users do not have to use the sensor code). When operating in factory calibration mode (using sensor code, the primary mode of G6 CGM System), the G6 algorithm does not require SMBG calibration and instead uses sensor glucose sensitivity estimates determined during manufacturing for EGV calculation. When operating in manual calibration mode (no sensor code), the G6 algorithm relies on daily SMBG calibrations and timematched sensor counts (matched pairs) to estimate calibration parameters for EGV calculation. When a SMBG calibration is entered into the system (in either mode), this information may be used by the system for estimating the glucose using the Bayesian Joint probability algorithm (JPA).

The proposed algorithm is modified to improve data availability by modifications to modules that handle noise events and calibrations when applicable. Additionally, the algorithm has been modified to improve detectability of sensors approaching end of life.

The Dexcom Glucose Program System is intended to replace fingerstick blood glucose testing for diabetes treatment decisions for persons with diabetes who are not at significant risk of severe hypoglycemia. Interpretation of the Dexcom Glucose Program System results should be based on the glucose trends and sequential sensor readings over time. The Dexcom Glucose Program System also aids in the detection of episodes of hyperglycemia, facilitating long-term therapy adjustments. The Dexcom Glucose Program System is also intended to autonomously communicate with digitally connected devices. The Dexcom Glucose Program System can be used alone or in conjunction with these digitally connected devices or services for the purpose of managing diabetes.

The proposed Dexcom G6 Glucose Program Continuous Glucose Monitoring System consists of three main components: the sensor/applicator delivery system, transmitter, and mobile application (app). The sensor is a small and flexible wire inserted into subcutaneous tissue where it converts glucose into electrical current. The transmitter is connected to the sensor and is worn on the body. It samples the electrical current produced by the sensor and converts these measurements into glucose readings using an onboard algorithm. The transmitter sends glucose data to either the Android app (part of the predicate system) or iOS app (part of the proposed system). The app displays the current glucose reading (updated every 5 minutes) and glucose trends from the transmitter. The app alert users of important system conditions, when it enters an error state, or when it requires the user to enter information. The app also supports connectivity to Dexcom Share and the Follow mobile application.
