Abstract: A multi-layer sensor assembly for use as a subcutaneous analyte sensor in a continuous monitoring system. The sensor assembly comprises a distal end portion, a proximal end portion, and a middle portion between the distal end portion and the proximal end portion, and three layers. The distal end portion comprises a first working electrode, a counter electrode, a second working electrode, and a reference electrode. The proximal end portion has a plurality of electrically conductive contact pads. The electrodes communicate electrically with the contact pads through the middle portion.

Abstract: A subcutaneous analyte sensor applicator includes an applicator module and a sensor module. The applicator module includes an applicator housing, a deployment button, and a pre-loaded insertion assembly completely disposed and secured within the button and partially disposed within the applicator housing when the button is in an initial, loaded position on the applicator housing. The insertion assembly includes an assembly housing, and a biasing element and a needle assembly disposed within the assembly housing chamber where the biasing element is in a compressed state. The sensor module includes a sensor lower housing releasably connected to the applicator housing, a sensor upper housing removably retained against the insertion assembly housing and spaced from the sensor lower housing, and an electro-sensor assembly disposed within the sensor upper housing where a sensor is temporarily disposed within a needle of a needle assembly when the applicator system is in the initial pre-loaded position.
