Inductive Link with Ferrite Sheets

An arrangement for a partially implantable medical system, the arrangement comprising:

• a communications coil adapted for placement parallel to a corresponding partner coil for communication of an implant communications signal having an associated magnetic field component;
• an implant electronics module adjacent to the communications coil and electrically connected with the communications coil for coupling of the communications signal;
• a planar coil shield lens between the communications coil and the electronics module to promote coupling of the communications signal between the communications coil and the partner coil and to shield the electronics module from interaction with the magnetic field component.
