An apparatus comprising:
- a hermetically-sealed biocompatible housing configured to be implanted in a recipient;
- and
- at least one trans-housing transformer configured to transfer electrical signals through the housing.
A method comprising:
- receiving one or more electrical signals at a trans-housing transformer partially disposed in a hermetically-sealed biocompatible housing configured to be implanted in a recipient;
- and
- transferring, via the trans-housing transformer, the one or more electrical signals through the housing.
An implantable medical device comprising:
- an external coil configured to be worn by a recipient;
- a hermetically-sealed biocompatible housing configured to be implanted in a recipient;
- implant electronics positioned in the housing;
- an implantable internal coil positioned external to the housing and configured to receive electrical signals transmitted by the external coil;
- and
- at least one trans-housing transformer configured to transfer the electrical signals received at the internal coil through the housing to the implant electronics.
