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.
Claims30
A sensor system for measuring an analyte concentration in a host, the system comprising:
- at least one electrode configured for implantation in a host and configured to measure an analyte concentration in a tissue of the host;
- sensor electronics operably connected to the at least one electrode and configured to provide analyte data representative of an analyte concentration in the host, wherein the sensor electronics are configured to provide an identification of sensor insertion into the tissue of the host or an identification of sensor removal from the tissue of the host;
- and
- an information tag comprising a code, wherein the code comprises sensor implantation information configured to control or limit an amount of time after sensor insertion into the tissue of the host over which information can be obtained from the at least one electrode, and wherein the code further comprises a number that represents how many sensor insertions into the tissue of the host are allowed using a unique license code.
1 more element
An analyte sensor assembly, the assembly comprising:
- a mounting unit adapted for mounting on a skin of a host;
- an electronics unit configured to releasably mate with the mounting unit, wherein the electronics unit is configured to provide an identification of sensor insertion into a tissue of the host or an identification of sensor removal from the tissue of the host;
- a sensor configured to measure a concentration of an analyte in the host, wherein the sensor is operably connected to the electronics unit when the electronics unit is mated to the mounting unit;
- and
- an information tag comprising a code, wherein the code comprises sensor implantation information configured to control or limit an amount of time after sensor insertion into the tissue of the host over which information can be obtained from the sensor, and wherein the code further comprises a number that represents how many sensor insertions into the tissue of the host are allowed using a unique license code.
2 more elements
A glucose sensor system, the sensor system comprising:
- a mounting unit adapted for mounting on a skin of a host;
- a sensor configured to measure an analyte concentration in the host;
- sensor electronics operably connected to the sensor, wherein the sensor is configured to provide data representative of an analyte concentration in the host, wherein the sensor electronics are configured to provide an identification of sensor insertion into a tissue of the host or an identification of sensor removal from the tissue of the host;
- a receiver remote from the mounting unit and configured to receive sensor data from the electronics unit, wherein the data is representative of a measured analyte concentration;
- and
- an information tag comprising a code, wherein the code comprises sensor implantation information configured to control or limit an amount of time after sensor insertion into the tissue of the host over which information can be obtained from the sensor, and wherein the code further comprises a number that represents how many sensor insertions into the tissue of the host are allowed using a unique license code.
