    a sheath coupled to and partially contained within the housing, wherein a distal end of the sheath defines a distal surface for placement on a skin surface and an entire width of a proximal end of the sheath is fully contained within the housing;

    an analyte sensor;

    an on-body housing;

    a sharp;

    a sharp holder coupled with the sharp, the sharp holder having at least one groove;

    a spring;

    a body having a projecting spring retention member with a plurality of tabs adapted to engage the at least one groove of the sharp holder, wherein the projecting spring retention member extends through a center of the spring;

    an on-body housing feature within the sheath operative to releasably retain the on-body housing, the on-body housing coupled to the analyte sensor and including a sensor control unit;

    a pusher coupled to and disposed within the housing and operative to translate the on-body housing and the sharp along a longitudinal axis of the inserter from a proximal position to a distal position in response to the housing being moved toward the distal surface relative to the sheath,wherein the inserter is operative to allow the spring to expand and remove the sharp holder and sharp from the on-body housing when the pusher reaches the distal position.
