1. A sensor assembly for a continuous glucose monitoring system, comprising:
a sensor carrier having a sensor unit receiving area and an electronics receiving area, the electronics receiving area including a substrate;
a sensor unit, comprising:
a sensor housing, a conductive member, a sensor comprising an insertion portion and a contact portion, an insertion shaft cover, an introducer comprising a handle and an insertion shaft, and a sealed, sterilized region,
wherein the sensor housing comprises:
a first opening extending from a bottom surface of the sensor housing, and
a second opening laterally displaced from the first opening and extending from the bottom surface to a top surface of the sensor housing,
wherein the insertion shaft cover is sealed against the top surface of the sensor housing and the handle is sealed against the bottom surface of the sensor housing,
wherein the sealed, sterilized region extends from an inner surface of the insertion shaft cover, through the second opening, and to the handle of the introducer,
wherein the insertion portion of the sensor and the insertion shaft are within the sealed, sterilized region,
wherein the conductive member is positioned outside of the sealed, sterilized region and is in electrical contact with the contact portion of the sensor outside of the sealed, sterilized region, and
wherein the conductive member extends through the first opening of the sensor housing; and
electronics for the continuous glucose monitoring system;
wherein the sensor unit is positioned within the sensor unit receiving area of the sensor carrier and the electronics are positioned on the substrate within the electronics receiving area of the sensor carrier so as to form the sensor assembly having the sensor electrically connected to the substrate of the electronics receiving area via the conductive member while maintaining sterilization of the sealed, sterilized region of the sensor unit.
