1. A cochlear implant system comprising:
a cochlear electrode;
a stimulator in electrical communication with the cochlear electrode;
a signal processor in communication with the stimulator, the signal processor including first circuitry, a first can surrounding and housing the first circuitry, and a first impedance between the first circuitry and the first can to reduce unintended electrical communication between the cochlear electrode and the first circuitry of the signal processor;
an input source in communication with the signal processor; and
an implantable battery and/or communication module, the implantable battery and/or communication module being configured to provide electrical power to the signal processor and including a signal generator configured to generate digital signals for communicating to the signal processor, second circuitry, a second can surrounding and housing the second circuitry, and a second impedance between the second circuitry and the second can to reduce unintended electrical communication between the cochlear electrode and the second circuitry of the implantable battery and/or communication module; wherein
the signal processor is in communication with the implantable battery and/or communication module via a first lead.
