An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices.
1. A method, comprising: positioning a distal end of an inserter on a skin surface; andapplying a force on a proximal end of the inserter to displace a sharp carrier, a device carrier and an analyte monitoring assembly from a first position within the inserter in spaced relation with the skin surfac
1. A method, comprising: positioning a distal end of an inserter on a skin surface; andapplying a force on a proximal end of the inserter to displace a sharp carrier, a device carrier and an analyte monitoring assembly from a first position within the inserter in spaced relation with the skin surface to a second position adjacent to the skin surface, and to position a portion of an analyte sensor under the skin surface and in contact with interstitial fluid, wherein a spring is positioned within the inserter in a compressed, preloaded state when the sharp carrier, the device carrier and the analyte monitoring assembly are in the first position, and wherein the spring is retained in the compressed, preloaded state without a change in state as the sharp carrier, the device carrier and the analyte monitoring assembly move from the first position to the second position; wherein the preloaded spring is biased to advance the sharp carrier from a retracted position with an introducer sharp extending through the device carrier and the analyte monitoring assembly to an extended position in spaced relation with the device carrier, wherein a plurality of carrier arms retain the sharp carrier in the retracted position, and wherein the sharp carrier is disengaged from the plurality of carrier arms permitting expansion of the preloaded spring to advance the sharp carrier to the extended position and withdraw the introducer sharp from the analyte monitoring assembly and the skin surface when the sharp carrier reaches the second position. 2. The method of claim 1, wherein the sharp carrier is disengaged by releasing compression from a support wall maintaining the plurality of carrier arms in an interference relationship with the sharp carrier until the sharp carrier reaches the second position. 3. The method of claim 2, wherein the support wall is configured to engage the sharp carrier by preventing the plurality of carrier arms from bending outwardly until the sharp carrier reaches the second position. 4. The method of claim 3, wherein the plurality of carrier arms are configured to clear the support wall when the sharp carrier reaches the second position. 5. The method of claim 4, wherein the plurality of carrier arms are configured to bend outwardly when the plurality of carrier arms clear the support wall. 6. The method of claim 5, wherein the plurality of carrier arms are configured to disengage from the sharp carrier when the plurality of carrier arms bend outwardly. 7. The method of claim 6, wherein when the plurality of carrier arms are configured to no longer be in an interference relationship with the sharp carrier when the plurality of carrier arms disengage from the sharp carrier. 8. The method of claim 1, wherein no springs are axially compressed during inserter actuation. 9. The method of claim 8, wherein no coil springs are compressed during the inserter actuation. 10. The method of claim 1, wherein the analyte sensor is operatively coupled to the analyte monitoring assembly. 11. The method of claim 10, wherein the analyte monitoring assembly is configured to receive the introducer sharp. 12. The method of claim 11, wherein when the analyte monitoring assembly reaches the second position, the analyte monitoring assembly is configured to adhere to the skin surface. 13. The method of claim 10, wherein the preloaded spring is configured to withdraw the introducer sharp to a proximal position within the inserter during expansion. 14. The method 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 at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer. 15. The method of claim 1, wherein the inserter includes a handle and a sheath. 16. The method of claim 15, wherein the introducer sharp is withdrawn into the handle and the sheath when the preloaded spring is released from the preloaded condition. 17. The method of claim 16, further comprising maintaining the handle in a fixed position relative to the sheath using a locking mechanism after the withdrawal of the introducer sharp from the analyte monitoring assembly and the skin surface. 18. The method of claim 1, wherein the analyte monitoring assembly includes sensor electronics operatively coupled to a housing. 19. The method of claim 18, wherein an adhesive layer is formed on a surface of the housing. 20. The method of claim 1, wherein the spring is coupled to the sharp carrier and the device carrier, and further wherein the spring is configured to move while in the compressed, preloaded state, with the sharp carrier, the device carrier and the analyte monitoring assembly from the first position to the second position.
