Assignee: DEXCOM, INC.
Field: Medical technology (Instruments)
Classification: CPC A  Y | IPC A

Claim 18:
19. A glucose monitoring system comprising:
a transcutaneous electrochemical glucose sensor comprising:
an in vivo portion configured to be inserted into a body of a host, wherein the in vivo portion of the transcutaneous electrochemical glucose sensor comprises an electrode and a membrane comprising glucose oxidase; and
an ex vivo portion configured to remain outside the body of the host;

a memory storing calibration information for the transcutaneous electrochemical glucose sensor, wherein the stored calibration information is based at least in part on information generated prior to insertion of the in vivo portion of the transcutaneous electrochemical glucose sensor in the host, wherein the stored calibration information is based at least in part on applying a predictive relationship that converts an in vitro sensitivity to glucose to a in vivo sensitivity to glucose, wherein the in vitro sensitivity to glucose is different from the in vivo sensitivity to glucose; and
a processor configured to calibrate data derived at least in part from in vivo measurements generated by the transcutaneous electrochemical glucose sensor after insertion of the in vivo portion of the transcutaneous electrochemical glucose sensor in the host, wherein the processor is configured to perform the calibrating based at least in part on the stored calibration information, and wherein the processor is configured to perform the calibrating without requiring calibration information obtained from a reference glucose measurement after insertion of the transcutaneous electrochemical glucose sensor.
