Abstract
A system for providing transdermal communication with, and power to, a subcutaneously implanted device, for example the stimulator unit of a cochlear implant, by means of pairs of orthogonally wound, inductively coupled coils. The system provides a compact coil arrangement particularly suited to behind the ear and in-the ear multi-channel cochlear implants.
