Earpiece assembly to interact with implantable neural stimulators
An ear-piece assembly includes (i) an antenna portion enclosing a transmitting antenna configured to send one or more input signals containing electrical energy to a passive implantable neural stimulator device such that the passive implantable neural stimulator generates one or more stimulation pulses suitable for stimulating a neural structure in the craniofacial region solely using the electrical energy in the input signals; and (ii) an enclosure coupled to the antenna portion, wherein enclosure is sized and shaped to be mounted on a helix portion of an ear such that, when worn by a patient, weight from the enclosure is distributed over the helix portion of the ear for the enclosure to rest thereon, wherein the enclosure includes (i) a controller module configured to provide the one or more input signals to the transmitting antenna, and (ii) a battery adapted to provide energy to the ear-piece assembly.
