Abstract

Method and apparatus for providing an integrated transmitter unit and sensor insertion mechanism is provided.

Claims

1. A system, comprising:

an integrated housing including sensor electronics operatively coupled to an analyte sensor, a portion of the analyte sensor extendable through the integrated housing at an insertion position selected from a plurality of insertion positions,

wherein the insertion positions are each defined by a discrete aperture and spaced apart in a base portion of the integrated housing, and wherein each insertion position corresponds to a different insertion site across a skin surface indicated by the integrated housing,

wherein the integrated housing is configured to mount across the skin surface at the plurality of insertion positions, and

wherein a transmitter unit of the sensor electronics is configured to be selectively disabled after a predetermined time period has elapsed since coupling to the analyte sensor; and

a sensor introducer assembly coupled to the integrated housing, the introducer assembly configured to position at least the portion of the analyte sensor under the skin surface at the selected insertion position.

2. The system of claim 1, wherein the sensor electronics includes the transmitter unit coupled to and in electrical contact with the analyte sensor, and configured to transmit one or more signals corresponding to a respective one or more signals received from the analyte sensor.

3. The system of claim 2, wherein the transmitter unit is configured to wirelessly transmit the one or more signals corresponding to the respective one or more signals received from the analyte sensor.

4. The system of claim 2, further including a receiver unit configured to receive the one or more signals transmitted by the transmitter unit.

5. The system of claim 4, wherein the receiver unit includes one of an infusion pump, a monitoring device, a personal digital assistant, a pager, or a mobile telephone.

6. The system of claim 2, wherein the one or more signals received from the analyte sensor substantially corresponds to a monitored analyte level under the skin surface.

7. The system of claim 1, wherein the introducer assembly is configured to be removably detached from the integrated housing.

8. The system of claim 1, wherein the analyte sensor is a glucose sensor.

9. The system of claim 1, wherein the predetermined time period comprises about 1 day or more.

10. The system of claim 1, wherein the introducer assembly is configured to be removed from the integrated housing after positioning of the at least the portion of the analyte sensor under the skin surface.

11. The system of claim 1, wherein the integrated housing is flexible to substantially conform to a shape of a body portion to which it is configured to be mounted.

12. The system of claim 1, wherein the analyte sensor comprises a plurality of electrodes including a working electrode, wherein the working electrode comprises an analyte-responsive enzyme and a mediator, wherein at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and wherein the at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.

13. The system of claim 1, wherein the integrated housing is configured to allow a plurality of analyte sensors to be concurrently inserted into multiple insertion sites across the skin surface corresponding to two or more of the plurality of insertion positions, and wherein the analyte sensor is included in the plurality of analyte sensors.

14. The system of claim 1, wherein the sensor introducer assembly is configured to pivot substantially about the insertion positions so as to collapse the sensor introducer assembly onto the base portion of the integrated housing.

15. The system of claim 1, wherein the integrated housing is configured to allow a plurality of analyte sensors to be serially inserted into multiple insertion sites across the skin surface corresponding to two or more of the plurality of insertion positions without change in configuration to the integrated housing, and wherein the analyte sensor is included in the plurality of analyte sensors.
