Abstract: Analyte monitoring device calibration is described. A calibration system generates calibration results for multiple analyte monitoring devices during a calibration evaluation process. To do so, the calibration system implements a calibration board that includes a single ground electrode shared by, but not physically connected to, the multiple analyte monitoring devices. An input voltage is applied to an analyte-sensing element of each of the multiple analyte monitoring devices. Analyte-sensing elements and the common ground electrode are placed into/in contact with a reference bath that includes a known concentration of an analyte to be measured. The input voltage causes each analyte-sensing element to generate an electrical current that is indicative of the reference bath analyte concentration. The calibration system includes a current meter that monitors the electrical current generated by each of the multiple analyte monitoring devices, which is interpreted by the calibration system to generate the calibration results.

Abstract: The present disclosure relates generally to bioactive releasing membranes utilized with implantable devices, such as devices for the detection of analyte concentrations in a biological sample. More particularly, the disclosure relates to novel bioactive releasing membranes, to devices and implantable devices including these membranes, methods for forming the bioactive releasing membranes on or around the implantable devices, and to methods for monitoring analyte levels in a biological fluid sample using an implantable analyte detection device.
