Application: Analyte sensor (Patent ID: US20230414140A1)

The patent filed by DexCom Inc. relates to systems and methods for continuous analyte measurement in a host's vascular system. The system includes a vascular access device, sensor, and sensor electronics for insertion into the host's circulatory system. The method involves evaluating the sensitivity of an implanted analyte sensor over time by receiving sensor data, calculating sensitivity intermittently, and assessing changes in sensitivity based on multiple time-spaced calculations. The evaluation is done using prior sensitivity information without relying on blood-glucose measurements.

The claims detail the method for evaluating sensitivity changes, including specific time periods for evaluation, averaging and filtering sensitivity measurements, comparing changes with criteria, and using the most recent sensitivity calculation for calibration. The method also involves measuring changes in solute transport of the sensor membrane and auto-calibrating the sensor based on the measured sensitivity changes. The process includes iterative evaluation of sensitivity calculations over time and using a priori sensitivity information throughout the sensor session. Overall, the patent focuses on improving the accuracy and reliability of continuous analyte measurement systems by effectively monitoring and calibrating sensor sensitivity over time.
