Figure 2. The Phenix M-Bone device consists of a pair of permanent magnets (one external, the controller, and one internal, the receiver, which transmit mechanical power to the implanted device) upper figure: the controller magnet; middle figure: a lever arm as a force amplifier; lower figure: a screw to convert alternating movements of the lever arm into continuous longitudinal one-way movements
