Method and apparatus for providing an introducer for transcutaneous placement of at least a portion of an analyte sensor through the skin of a patient is provided.
1. A method, comprising: aligning a tapered end of an introducer substantially onto a sensor insertion site by positioning a housing over the insertion site, the introducer coupled to a sensor and the housing and the sensor having a portion provided within the housing;piercing a skin layer at the se
1. A method, comprising: aligning a tapered end of an introducer substantially onto a sensor insertion site by positioning a housing over the insertion site, the introducer coupled to a sensor and the housing and the sensor having a portion provided within the housing;piercing a skin layer at the sensor insertion site with the tapered end of the introducer with a drive mechanism detachably coupled to the housing to provide insertion force to the introducer during sensor insertion;guiding the sensor with the introducer through the skin layer, the introducer including a segment for limiting movement of the sensor when the sensor is guided through the skin layer;retracting the introducer from the skin layer while subcutaneously retaining at least a portion of the sensor under the skin layer;retaining the introducer within the housing after retraction from the skin layer and sensor insertion through the skin layer; anddetachably removing the drive mechanism from the housing after the sensor is guided through the skin layer and the introducer is retained within the housing; wherein the introducer includes a body portion and a shaft portion extending substantially from an edge of the body portion, the shaft portion including a tapered end and a segment, the shaft portion retaining the sensor, and further, the tapered end guiding the sensor through the skin layer during sensor insertion and the segment limiting movement of the sensor when the sensor is guided through the skin layer. 2. The method of claim 1, including maintaining the retracted introducer within the housing. 3. The method of claim 1, wherein the sensor includes an analyte sensor. 4. The method of claim 1, wherein guiding includes substantially entirely retaining at least a portion of the sensor within the shaft portion of the introducer. 5. The method of claim 1, wherein the tapered end of the introducer includes a substantially sharp edge segment configured to pierce the skin layer. 6. The method of claim 5, wherein the sharp edge segment of the tapered end is substantially configured at an angle greater than 45 degrees relative to direction of the sharp edge segment piercing the skin layer. 7. The method of claim 1, wherein the 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 at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer. 8. An analyte monitoring system, comprising: a housing;a sensor having apportion provided within the housing;an introducer coupled to the sensor and the housing, the introducer including: a body portion; anda shaft portion extending substantially from an edge of the body portion, the shaft portion including a tapered end and a segment, the shaft portion retaining the sensor, and further, the tapered end guiding the sensor through a skin layer during sensor insertion and the segment limiting movement of the sensor when the sensor is guided through the skin layer, wherein the introducer, the housing, and the sensor are configured such that, after retraction of the introducer from the skin layer, the sensor remains inserted through the skin layer and the introducer is retained within the housing; anda drive mechanism detachably coupled to the housing to provide insertion force to the introducer during sensor insertion, the drive mechanism detached from the housing after the sensor is guided through the skin layer and the introducer is retained within the housing. 9. The system of claim 8, further including a receiver operatively coupled to a transmitter disposed in the housing, the receiver further configured to receive data from the transmitter. 10. The system of claim 9, wherein the transmitter is configured to wirelessly transmit the data. 11. The system of claim 8, wherein the sensor is configured to monitor a level of an analyte. 12. The system of claim 11, wherein after the sensor is guided through the skin layer, the sensor is in contact with interstitial fluid. 13. The system of claim 8, wherein the drive mechanism is reusable. 14. The system of claim 8, wherein the housing includes a spring coupleable to the drive mechanism for providing the insertion force. 15. The system of claim 8, wherein the drive mechanism is one of a spring biased mechanism, magnetic force implementation, or a motor and gear combination. 16. The system of claim 8, wherein the drive mechanism is activated using one or more of an activation button, a lever, a plunger, a switch, or a knob. 17. The system of claim 8, wherein a transmitter unit is coupled to the housing after insertion of the sensor and detachment of the device mechanism from the housing. 18. The system of claim 17, wherein the transmitter unit is configured to transmit a level of an analyte to a remote device. 19. The system of claim 18, wherein the remote device includes a receiver unit, monitoring unit and/or an insulin pump. 20. The system of claim 18, wherein the transmitter unit is configured for wireless communication. 21. The system of claim 8, wherein the tapered end of the shaft portion is configured to pierce the skin layer. 22. The system of claim 8, wherein the shaft portion is substantially hollow. 23. The system of claim 8, wherein the shaft portion includes an opening substantially along a length of the shaft portion. 24. The system of claim 23, wherein the opening is configured to be wider than a width of the sensor retained therein, such that the sensor may be displaced out of the shaft portion through the opening. 25. The system of claim 8, wherein the 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 at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.
