1. A reusable sensor assembly (RSA) comprising:

  • a RSA housing;

    a transmitter disposed within the RSA housing; and

    a microcontroller coupled to the transmitter, the microcontroller configured to be communicatively coupled to a disposable sensor assembly (DSA) having an analyte sensor, the microcontroller also configured to receive measurement signals from the DSA and to cause the transmitter to transmit telemetry signals in response to the received measurement signals;

    wherein, prior to insertion of the analyte sensor into skin, the analyte sensor is at least partially disposed within a DSA housing of the DSA and the analyte sensor is in contact with a sensor insertion guidance structure disposed in the DSA housing;

    wherein the RSA is removably secured to the DSA housing prior to and during the passing of the analyte sensor out the opening in the DSA housing; and

    wherein the sensor insertion guidance structure is configured to remain disposed in the DSA housing after insertion of the analyte sensor into skin and during receipt of the measurement signals by the RSA.
