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.

First claim

What is claimed is:

1. A system for measuring an analyte concentration in a host, the system comprising:
a sensor system comprising:
a first component comprising a sensor configured to measure a signal indicative of an analyte concentration in the host, and a second component comprising sensor electronics configured to operably connect to the sensor, wherein the sensor electronics comprise:
one or more memories configured to store data indicative of analyte concentrations derived at least in part from measurements from the sensor;
a radio frequency module configured to wireles sly transmit at least some of the data indicative of analyte concentrations to a receiver that comprises a display configured to display one or more estimated analyte concentration values, wherein the radio frequency module is configured to transmit at least some of the data indicative of analyte concentrations to the receiver in response to the receiver interrogating the sensor electronics;

wherein the first component is unconnected to the second component during a first state, wherein during a second state the first component is configured to be connected to the second component by the host to form an assembly before the assembly is affixed to the host for sensor insertion.

2. The system of claim 1 , wherein the second component comprises a housing, wherein the sensor comprises an in vivo portion and an ex vivo portion, and wherein the housing is configured to receive the ex vivo portion of the sensor.

3. The system of claim 1 , wherein the sensor electronics are configured to receive inductive power from the receiver.

4. The system of claim 1 , wherein the system is configured to have a sensor lifetime of about 14 days.

5. The system of claim 1 , wherein both the first component and the second component are labeled with an alphanumeric code.

6. The system of claim 5 , wherein the alphanumeric code is unique to the system.

7. The system of claim 5 , wherein the alphanumeric code is associated with sensor calibration information.

8. The system of claim 5 , wherein the alphanumeric code is stored in the sensor electronics.

9. The system of claim 8 , wherein the alphanumeric code is associated with sensor calibration information.

10. The system of claim 8 , wherein the sensor electronics are configured to transmit the alphanumeric code upon activation of the sensor system.

11. The system of claim 9 , wherein the sensor electronics are configured to transmit the alphanumeric code upon activation of the sensor system.

12. The system of claim 11 , wherein the sensor calibration information is configured to enable use of the system without requiring a reference analyte measurement during sensor use.

13. The system of claim 1 , wherein during a third state the first component is connected to the second component.

14. The system of claim 13 , wherein during a fourth state the sensor is transcutaneously implanted in the host.

15. The system of claim 1 , wherein the radio frequency module comprises an antenna that extends substantially around a periphery of a housing of the sensor electronics.

16. A system for measuring an analyte concentration in a host, the system comprising:
a sensor system comprising:
a first component comprising a sensor configured to measure a signal indicative of an analyte concentration in the host, and
a second component comprising sensor electronics configured to operably connect to the sensor, wherein the sensor electronics comprise:
one or more memories configured to store data indicative of analyte concentrations derived from measurements from the sensor;
a radio frequency module configured to wireles sly transmit at least some of the data indicative of analyte concentrations to a receiver that comprises a display configured to display one or more estimated analyte concentration values, wherein the radio frequency module is configured to transmit at least some of the data indicative of analyte concentrations to the receiver in response to the receiver interrogating the sensor electronics;

wherein the first component is unconnected to the second component during a first state, wherein during a second state the first component is configured to be connected to the second component by the host to form an assembly before the assembly is affixed to the host for sensor insertion, and
wherein at least one of the first component and the second component is labeled with an alphanumeric code, wherein the alphanumeric code is associated with sensor calibration information, and wherein the alphanumeric code is stored in the one or more memories.

17. The system of claim 16 , wherein the sensor electronics are configured to transmit the alphanumeric code upon activation of the sensor system.

18. A system for measuring an analyte concentration in a host, the system comprising:
a sensor system comprising:
a first component comprising a sensor configured to measure a signal indicative of an analyte concentration in the host, and
a second component comprising sensor electronics configured to operably connect to the sensor, wherein the sensor electronics comprise:
one or more memories configured to store data indicative of analyte concentrations derived from measurements from the sensor;
a radio frequency module configured to wireles sly transmit at least some of the data indicative of analyte concentrations to a receiver that comprises a display configured to display one or more estimated analyte concentration values;

wherein the first component is unconnected to the second component during a first state, wherein during a second state the first component is configured to be connected to the second component by the host to form an assembly before the assembly is affixed to the host for sensor insertion, and
wherein at least one of the first component and the second component is labeled with an alphanumeric code.

19. The system of claim 18 , wherein the alphanumeric code is stored in the sensor electronics.

20. The system of claim 18 , wherein the alphanumeric code is associated with sensor calibration information.

21. The system of claim 20 , wherein the sensor calibration information is stored in the sensor electronics.

22. The system of claim 18 , wherein both the first component and the second component are labeled with an alphanumeric code.
