Claim 0:
1. An assembly of components for mounting an analyte sensor and an electronics compartment on a user, the assembly comprising:
a housing defining a sealed sensor compartment, the housing comprising an upper cap, a lower cap, and an electronics compartment, the electronics compartment receiving at least a portion of an electronics unit;
an analyte sensor comprising an insertable portion, the insertable portion being adapted for at least being partially inserted into a user's body tissue; and
a cannula attached to the upper cap, the insertable portion of the analyte sensor being received inside the cannula,
an insertion aid configured for driving the cannula into the user's skin, and for inserting the insertable portion of the analyte sensor into the user's skin,
the electronics compartment and the sealed sensor compartment being connected to each other via at least one sealed opening, the analyte sensor extending from the sealed sensor compartment through the sealed opening to the electronics compartment,
the analyte sensor being operably connected to the electronics unit,
the electronics compartment defining a cannula aperture extending from an upper surface opening to a lower surface opening,
the lower cap being configured to seal with the lower surface opening of the electronics compartment, the lower cap comprising an interior volume receiving the cannula and the insertable portion of the analyte sensor,
the upper cap being configured to seal with the upper surface opening of the electronics compartment,
the lower cap being configured for removal prior to insertion of the analyte sensor,
the upper cap and the cannula being configured for removal from the electronics compartment after insertion of the analyte sensor,
the cannula extending downwardly from the upper cap, through the cannula aperture, and beyond the lower surface opening, the insertable portion of the analyte sensor extending downwardly within the cannula and beyond the lower surface opening, and the lower cap extending downwardly from the electronics compartment,
the housing having a sealed condition, prior to insertion of the analyte sensor, in which the upper cap, the lower cap and the electronics compartment form the sealed sensor compartment surrounding and sealing the cannula and the insertable portion of the analyte sensor from an external environment,
the upper cap and the electronics compartment being configured to move together to insert the cannula and the insertable portion of the analyte sensor into the user's body tissue, and
the upper cap and the cannula being configured to be removed together from the user's body tissue after insertion of the insertable portion of the analyte sensor, leaving the analyte sensor implanted in the user's body tissue.
