Continuous blood glucose monitor

implantable

The miniaturized Senseonics Sensor is designed to measure glucose in the interstitial fluid for up to six months. Unlike current glucose sensors, the Senseonics Sensor is intended to be implanted subcutaneously on the upper arm with no sensor part protruding from the skin. Encased in a biocompatible material, the Sensor 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 Transmitter. This entire measurement is designed to be done autonomously and independently without any prompting by the user. The fluorescent glucose chemistry is well known and is not subject to the instabilities intrinsic to current protein based glucose sensors. No chemicals are consumed (i.e. oxygen, glucose) or formed (i.e. hydrogen peroxide). Consequently, this technology is expected to be inherently more stable and accurate.
