Abstract

Devices and methods for positioning a portion of a sensor at a first predetermined location, displacing the portion of the sensor from the first predetermined location to a second predetermined location, and detecting one or signals associated with an analyte level of a patient at the second predetermined location are disclosed. Also provided are systems and kits for use in analyte monitoring.

Claims

1. A method, comprising:

positioning at least a portion of an analyte sensor at a first predetermined location under a skin surface at a first predetermined speed;

displacing the portion of the analyte sensor from the first predetermined location to a second predetermined location at a second predetermined speed slower than the first predetermined speed;

detecting one or more signals associated with an analyte level of a patient at the second predetermined location; and

wirelessly transmitting data corresponding to the one or more signals associated with the analyte level of the patient to a receiving device.

2. The method of claim 1, wherein the receiving device is a first receiving device, and further comprising wirelessly transmitting the data corresponding to the one or more signals associated with the analyte level of the patient to a second receiving device concurrently with wirelessly transmitting the data corresponding to the one or more signals associated with the analyte level of the patient to the first receiving device.

3. The method of claim 2, further comprising forming a communication link between the first receiving device and the second receiving device.

4. The method of claim 1, wherein the receiving device comprises a display.

5. The method of claim 4, further comprising determining that the analyte level is at or near a threshold level, and in response providing a notification on the display.

6. The method of claim 1, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

7. The method of claim 6, wherein the analyte-responsive enzyme is chemically bonded to the polymer.

8. The method of claim 6, wherein the working electrode further comprises a mediator.

9. The method of claim 1, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

10. The method of claim 9, wherein the mediator is chemically bonded to the polymer.

11. A system, comprising:

a receiving device;

an analyte sensor having a portion for positioning at a first predetermined location under a skin surface at a first predetermined speed, the analyte sensor further configured to have the portion displaced from the first predetermined location to a second predetermined location at a second predetermined speed slower than the first predetermined speed, wherein the analyte sensor is configured to detect one or more signals associated with an analyte level of a patient at the second predetermined location; and

sensor electronics communicatively coupled to the analyte sensor for wirelessly transmitting data corresponding to the one or more signals associated with the analyte level of the patient to the receiving device.

12. The system of claim 11, wherein the receiving device is a first receiving device;

further comprising a second receiving device; and

wherein the sensor electronics is further configured to wirelessly transmit the data corresponding to the one or more signals associated with the analyte level of the patient to the second receiving device concurrently with wirelessly transmitting the data corresponding to the one or more signals associated with the analyte level of the patient to the first receiving device.

13. The system of claim 12, wherein a communication link exists between the first receiving device and the second receiving device.

14. The system of claim 11, wherein the receiving device comprises a display.

15. The system of claim 14, wherein the receiving device is configured to determine that the analyte level is at or near a threshold level, and in response provide a notification on the display.

16. The system of claim 11, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

17. The system of claim 16, wherein the analyte-responsive enzyme is chemically bonded to the polymer.

18. The system of claim 16, wherein the working electrode further comprises a mediator.

19. The system of claim 11, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

20. The system of claim 19, wherein the mediator is chemically bonded to the polymer.
