Guardian™ Sensor 3.
Manage glucose levels with a smarter CGM (Continuous Glucose Monitoring) system, powered by Guardian™ Sensor 3. Guardian Sensor 3 may be used as part of the MiniMed® 770G/670G system for ages 2 and up. Sensor is indicated for use on arm and abdomen.

Sensor Improvements:
REMOVED TUBING:
- Provides a sensor with an 80% reduction in implantable volume compared to previous sensors
- Thicker sensor; shim adds rigidity
- More flexibility in sensor; less likely to bend or kink
MORE CONSISTENT PLATING:
- Reduces variability and increases consistency
- Similar to metal plating of jewelry
ELECTRODE DESIGN:
- Improved performance
- Increased number of electrodes allows for sensing along the entire length of sensor
- Better distribution of the “work”; more robust
ADDITIONAL TAPE BARRIER LAYER:
- Increased comfort, reduced skin irritation
- Ensures maximum patch adhesion to the body
- More comfortable to wear
SMART CGM WITH NEW DIAGNOSTIC TECHNOLOGY:
A smart diagnostic chip in the Guardian™ Link 3 transmitter continuously monitors our sensor health to optimise performance and ensure reliability
