Abstract

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

Claims

1-20. -20. (canceled)

21. A sensor system for measuring an analyte concentration in a host, the system comprising:

a transcutaneous analyte sensor configured for insertion into a host'"'"'s tissue, wherein the transcutaneous analyte sensor comprises an in vivo portion and an ex vivo portion, wherein the transcutaneous analyte sensor is configured to generate sensor data associated with an analyte concentration in the host; and

a mounting unit configured to be placed on a skin of the host, wherein the mounting unit is configured to receive the ex vivo portion of the transcutaneous analyte sensor, wherein the mounting unit comprises an electronics unit, wherein the electronics unit comprises a processor configured to process the generated sensor data.

22. The system of claim 21, wherein the mounting unit comprises a power source configured to power the electronics unit.

23. The system of claim 21, wherein the electronics unit is operatively connected to the transcutaneous analyte sensor.

24. The system of claim 21, wherein the electronics unit comprises an antenna configured to radiate or receive a radio frequency transmission.
