Summary:An implantable control module for an electrical stimulation system includes an electronic subassembly disposed in a casing. A sealed feedthrough housing is disposed along a portion of the casing. An electrically-conductive portion of the feedthrough housing is electrically coupled to an electrically-conductive portion of the casing. Feedthrough pins extend through the feedthrough housing and couple to the electronic subassembly via conductive pathways disposed in the casing. At least a portion of the conductive pathways extend along a non-conductive substrate. An RF-diverting assembly is disposed in the casing. The RF-diverting assembly includes a feedthrough ground electrically coupled to the electrically-conductive portion of the feedthrough housing. The RF-diverting assembly also includes a plurality of capacitive elements each coupling a different one of the plurality of conductive pathways to the feedthrough ground.
