1. An implantable adapter for coupling an implantable lead to an implantable medical device, the adapter comprising:

  • a housing of the implantable adapter configured at a first end to form a first mechanical connector to provide a reversible mechanical connection to a proximal end of the implantable lead and configured at a second end to form a second mechanical connector to provide a reversible mechanical connection to the implantable medical device, wherein the implantable medical device comprises an implantable medical device housing separate from the housing of the implantable adapter;

    a first resonant circuit within the housing of the implantable adapter, the first resonant circuit having a resonance frequency approximately equal to a frequency of a first electromagnetic radiation source;

    a second resonant circuit within the housing of the implantable adapter and connected in series with the first resonant circuit, the second resonant circuit having a resonance frequency approximately equal to a frequency of a second electromagnetic radiation source;

    a first wire within the housing of the implantable adapter to electrically connect a first wire of the implantable lead to the first resonant circuit; and

    a second wire within the housing of the implantable adapter to electrically connect the second resonant circuit to the implantable medical device.
