Mandibular repositioning devices have a mandibular piece having a first teeth covering and having a housing proximate each of a left molar portion and a right molar portion, a protrusive flange extending cranially from each housing, and a maxillary piece having a second teeth covering and having a housing proximate each of a left molar portion and a right molar portion. Each housing encloses a power source electrically connected an on-board circuit board and the housings of the maxillary piece further have the power source electrically connected to a motor operatively connected to a drive for anterior and posterior movements of the mandibular piece. The maxillary piece sits on the mandibular piece with the driver operatively engaged with the protrusive flange. The protrusive flange has a concavely-shaped anterior surface mated to a convexly-shaped head of the driver shaped to match the concavely-shaped anterior surface of the protrusive flange.

Passive tissue biasing circuitry in an Implantable Pulse Generator (IPG) is disclosed to facilitate the sensing of neural responses by holding the voltage of the tissue to a common mode voltage (Vcm). The IPG's conductive case electrode, or any other electrode, is passively biased to Vcm using a capacitor, as opposed to actively driving such electrode to a prescribed voltage using a voltage source. Once Vcm is established, voltages accompanying the production of stimulation pulses will be referenced to Vcm, which eases neural response sensing. An amplifier can be used to set a virtual reference voltage and to limit the amount of current that flows to the case during the production of Vcm. Circuitry can be used to monitor the virtual reference voltage to enable sensing neural responses, and to set a compliance voltage for the current generation circuitry.
