  • positioning an end of the base of the inserter on a skin surface of a subject, the inserter containing an analyte monitoring assembly including a power source and electronics coupled to an analyte sensor and operable to communicate analyte data;

    moving the shuttle, the shuttle surface in contact with the spring, the analyte monitoring assembly, and the introducer mechanism from a first position within the inserter to a second position where at least a portion of the analyte sensor of the analyte monitoring assembly is brought into contact with fluid in the subject; and

    automatically retracting the shuttle and the introducer mechanism away from the skin surface and into the inserter with a force applied by the spring against the shuttle surface, while the end of the base is maintained on the skin surface.
