Method and apparatus for providing analyte sensor insertion
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.
1. An assembly, comprising:
a sensor;
a mounting unit for placement on the skin of a patient;
a sensor introducer coupled to the sensor and to the mounting unit, the sensor introducer configured to transcutaneously introduce a portion of the sensor through a skin of the patient to a first position relative to the mounting unit;
a data processing unit configured to couple to the mounting unit, the data processing unit displacing the sensor to a second position relative to the mounting unit upon coupling to the mounting unit.
2. The assembly of claim 1 wherein the first position is closer to the mounting unit of the patient than the second position.
3. The assembly of claim 1 wherein the sensor includes an engagement portion configured to couple to a housing of the data processing unit, such that the portion of the sensor is displaced with the movement of the data processing unit when coupling to the mounting unit.
4. The assembly of claim 1 wherein the data processing unit is configured to be in electrical contact with the sensor to receive one or more signals associated with an analyte of the patient.
5. The assembly of claim 4 wherein the data processing unit is coupled to the mounting unit when in electrical contact with the sensor.
6. The assembly of claim 4 wherein the data processing unit transmits data associated with the one or more signals associated with the analyte.
7. The assembly of claim 6 wherein the data processing unit wirelessly transmits the data to a remote location.
8. The assembly of claim 7 wherein the transmitted data are output at the remote location.
9. The assembly of claim 1 wherein the sensor includes a glucose sensor.
10. The assembly of claim 1 wherein the sensor introducer includes a deployment mechanism to transcutaneously introduce the portion of the sensor.
11. The assembly of claim 10 wherein the deployment mechanism is actuated to transcutaneously introduce the portion of the sensor.
12. The assembly of claim 10 wherein the deployment mechanism includes a manual deployment mechanism.
13. The assembly of claim 10 wherein the deployment mechanism includes a spring biased deployment mechanism.
14. The assembly of claim 1 wherein the sensor is positioned at the first position prior to being positioned at the second position.
15. The assembly of claim 1 wherein the sensor is maintained at the second position during the sensing time period.
16. The assembly of claim 15 wherein the sensing time period includes one of approximately three days, approximately five days, or approximately seven days.
17. The assembly of claim 1 wherein the sensor includes a working electrode formed with one or more of carbon, gold, metal alloy or a conductive polymer.
18. The assembly of claim 1 wherein the portion of the sensor is transcutaneously introduced through the skin to the first position at a first angle relative to a surface of the skin, and further, wherein the transcutaneously introduced sensor is displaced to the second position at a second angle relative to the surface of the skin.
19. The assembly of claim 18 wherein the first angle and the second angle are the same.
20. The assembly of claim 18 wherein one or more of the first angle and the second angle are approximately 90 degrees or less.
