Abstract

A continuous analyte monitoring assembly is adapted to assist in determining an analyte level of a fluid. The monitoring assembly includes a housing, electronics, an implantable sensor and a cannula. The housing has a bottom in which the bottom forms a recess. The electronics are located within the housing and assist in determining an analyte level of a fluid sample. The sensor moves from a retracted position to an inserted position using the recess. The cannula assists in placing the implantable sensor.

Claims
