Claim 0:
1. A hearing aid device comprising
an external unit configured to be worn proximate to a user's ear, the external unit comprising
an electronic unit operationally coupled to a transmitter coil that is configured transmit power and/or data signal over a wireless transcutaneous link,
a coil unit comprising a loop structure with the transmitter coil being wound around and along at least a part of length of the loop structure,
a fixation unit configured to attach the loop structure to the user's ear proximal to a loop-shaped implantable receiver coil that is configured to be implanted within the ear or around the ear of the user such that a part of the ear is positioned in a hollow section of the loop structure; and

an implantable unit comprising
the implantable receiver coil configured to receive the power and/or data signal over the wireless transcutaneous link, and
a processing unit configured to i) process the received data signal to control functionalities of at least one of the components of the implantable unit, and/or ii) utilize the received power for operation of at least one of the components of the implantable unit,

wherein
the wireless transcutaneous link comprises a coupling between the transmitter coil and the receiver coil, and
when the loop structure is attached using the fixation unit such that at least a substantial number of magnetic field lines generated in response to excitation of the transmitter coil passes through the opening in the loop-shaped implantable receiver coil.
