1. A method of operating an inserter comprising a base, a spring, an introducer mechanism, and a shuttle that is coupled with the introducer mechanism, the shuttle having a surface in contact with the spring, the method comprising:
- 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.
