A microphone is installed on a surface of the skin immediately below the mastoid of a human to implement a sound sampling method including sampling at least one of a non-audible murmur, a whisper, or an audible sound. An actuator disk is mounted within the peripheral wall overlying the deck and the dispensing opening, and is pivotal between a closed position closing the opening and an open position for dispensing product from the opening through the actuator disk. Apparatus for stimulation is permanently implanted in the body.
