16. 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 3.5 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.
