14. About the Sensor
This section describes the Eversense Sensor and how it is inserted by your physician.
The Eversense Sensor is a miniaturized fluorometer that uses fluorescent intensity to measure glucose in
interstitial fluid. The sensor is implanted subcutaneously (under the skin) on the upper arm, leaving no
part of the sensor protruding from the skin. The sensor remains in place and provides CGM measurements
for up to 90 days.
The sensor is encased in a biocompatible material and utilizes a unique fluorescent, glucose indicating
polymer. A light emitting diode embedded in the sensor excites the polymer, and the polymer then rapidly
signals changes in glucose concentration via a change in light output. The measurement is then relayed to
the smart transmitter. Measurements are completed automatically and require no action by the user.
The sensor is approximately 3.3 mm x 18.3 mm and has a silicone ring that contains a small amount of
dexamethasone acetate, an anti-inflammatory steroid drug. The dexamethasone acetate minimizes
inflammatory responses, very similar to common medical devices, such as pacemakers.
Insertion Steps
Your physician will explain and perform the simple and quick steps to insert the sensor. You will be fully awake during the approximately 5-minute
insertion procedure.
Insertion site:
It is important to choose a site that is comfortable for you to wear the sensor and smart transmitter for the entire 90 day period. It is recommended
to have the sensor inserted toward the back of the upper arm. Placement in this area minimizes the chance of the sensor and smart transmitter being
bumped by doorways, walls or other narrow passages. If possible, avoid areas with loose skin, scars, tattoos, nevus, or blood vessels that could be incised
during the procedure.
