Claims30
A device, comprising:
- an implantable sensor configured to continuously measure in vivo signals associated with an analyte concentration;
- and
- a membrane located over the sensor;
- wherein the implantable sensor is configured to generate signals associated with the analyte concentration having a level of accuracy corresponding to a mean absolute relative difference, wherein the level of accuracy increases on subsequent days during a sensor session of at least 3 days, wherein one or more reference measurements associated with a calculation of the mean absolute relative difference are determined by analysis of blood.
