System description
The Guardian 4 system includes the following components: Guardian iOS™* app (MMT-8200) or
Guardian Android™* app (MMT-8201), Guardian 4 transmitter (MMT-7841Q), Guardian 4 sensor
(MMT-7040Q), and compatible tester and charger.
Continuous glucose monitoring (CGM) is a technology that lets patients continuously view glucose
values. The Guardian 4 system uses a glucose sensor, the Guardian 4 sensor, placed below the skin, to
continuously measure the amount of glucose in the interstitial fluid. The Guardian 4 transmitter
collects and processes these glucose measurements, which are then displayed on the Guardian app.
The Guardian app can also provide alerts based on sensor glucose (SG) levels.
The Guardian app also provides a user interface for entering data such as exercise, insulin, meals, blood
glucose (BG) values, and uploading information to the CareLink Personal website.
The Guardian app is available to download from the Apple™* App Store™* or the Google Play™* store
and requires the Guardian 4 sensor and Guardian 4 transmitter to function.
Note: This product should only be used with supported mobile devices and operating systems.
Refer to the local Medtronic website for information about supported devices and operating
systems.
