Abstract
An implantable control module for an implantable electrical stimulation system includes a housing with at least a portion of the exterior forming a metallic structure and at least a portion of the interior defining a sealed compartment. The control module further includes an electronic subassembly disposed in the sealed compartment; a connector assembly coupled to the housing and defining a port for receiving a lead; connector contacts disposed in the port to electrically couple with terminals of the lead; feedthrough interconnects extending from the connector assembly into the sealed compartment and coupling the connector contacts to the electronic subassembly; and a coil disposed within or on the housing and configured and arranged to be shorted when an external electromagnetic field is applied in order to resist generation of an eddy current in the metallic structure of the exterior of the sealed housing in response to the external electromagnetic field.
