Abstract
An inductive coil arrangement is described for an ear canal of a recipient patient. An external transmitter coil is configured for implantation in the pinna cartilage of the outer ear of a recipient patient and has transmission wire loops wound about a first radial center. An implantable receiver coil is configured for implantation behind the pinna of the outer ear under the skin atop and parallel to the underlying skull bone of the recipient patient opposite to the transmitter coil with the pinna cartilage between. The receiver coil has receiver wire loops wound about a second radial center, the loops and the second radial center all lying substantially in a common plane, and the receiver coil is adapted for receiving the communication signal from the transmitter coil.
