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:

transcutaneously positioning an analyte sensor at a first predetermined location, the analyte sensor configured for fluid contact with interstitial fluid under a skin layer; and

coupling a data processing unit to a mounting unit such that the analyte sensor is displaced to a second predetermined location when the data processing unit is coupled to the mounting unit.

2. The method of claim 1, wherein transcutaneously positioning the sensor at the first predetermined location includes deploying the sensor at a first predetermined speed.

3. The method of claim 2, wherein displacing the sensor includes displacing the sensor to the second predetermined location at a second predetermined speed.

4. The method of claim 3, wherein the first predetermined speed is at a higher velocity than the second predetermined speed.

5. The method of claim 1, wherein displacing the sensor to the second predetermined location includes manually displacing the sensor.

6. The method of claim 1, further including retaining the sensor at the second predetermined location during a useful life of the sensor.

7. The method of claim 1, further including wirelessly transmitting signals generated by the analyte sensor to a remote location.

8. The method of claim 1, further including calibrating signals generated by the analyte sensor.

9. The method of claim 1, further including displaying data associated with a monitored analyte level based on signals generated by the analyte sensor.

10. The method of claim 1, further including processing signals generated by the analyte sensor with the data processing unit.

11. The method of claim 1, wherein the analyte sensor is transcutaneously positioned at the first predetermined location at a first angle relative to the skin layer, and further, wherein the analyte sensor is displaced to the second predetermined location at a second angle relative to the skin layer.

12. The method of claim 1, wherein transcutaneously positioning the analyte sensor at the first predetermined location includes coupling an introducer to the analyte sensor for transcutaneous positioning.

13. The method of claim 12, further including removing the introducer from the analyte sensor after transcutaneously positioning the analyte sensor at the first predetermined location.

14. An apparatus, comprising:

a mounting unit for placement on a skin layer;

an analyte sensor;

an introducer coupled to the analyte sensor and configured to transcutaneously position the analyte sensor at a first predetermined location in fluid contact with interstitial fluid under the skin layer; and

a data processing unit configured to couple to the mounting unit such that the analyte sensor is displaced to a second predetermined location when the data processing unit is coupled to the mounting unit.

15. The apparatus of claim 14, wherein the sensor is manually displaced to the second predetermined location.

16. The apparatus of claim 14, wherein the data processing unit is configured to process signals associated with a monitored analyte level received from the analyte sensor.

17. The apparatus of claim 16, wherein the data processing unit is configured to transmit the processed signals associated with the monitored analyte level received from the analyte sensor to a remote location.

18. The apparatus of claim 14, wherein the introducer is removed from the analyte sensor after the analyte sensor is transcutaneously positioned at the first predetermined location.
