Abstract
In an implantable prosthesis system such as a cochlear implant, a pair of coils are used to exchange control and/or power signals between the external and internal components. The coils are offset or displaced laterally by a predetermined distance to reduce variations in the signal transmission due to the spacing between the external and internal components.
