Classification: CPC A  Y | IPC A

Claim 15:
16. 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, the in vivo portion having at least one electrode and a membrane containing glucose oxidase, and
an ex vivo portion configured to remain outside of the body of the host;

a memory storing calibration information for the transcutaneous electrochemical glucose sensor, the calibration information generated by applying a predictive relationship for converting sensitivity information obtained prior to insertion of the transcutaneous electrochemical glucose sensor in the host to a different in vivo sensitivity of the transcutaneous electrochemical glucose sensor; and
a processor programmed to determine an estimated glucose value by applying the in vivo sensitivity of the transcutaneous electrochemical glucose sensor to an in vivo measurement from the in vivo portion of the transcutaneous electrochemical glucose sensor,
wherein the estimated glucose value is determined without any reference glucose concentration measurements obtained after insertion of the in vivo portion of the transcutaneous electrochemical glucose sensor into the body of the host.
