Abstract:
1. An implantable control module for an electrical stimulation system, the control module comprising: a sealed body; an electronic subassembly disposed in the sealed body and configured and arranged to generate electrical stimulation signals for delivery through a lead coupled to the implantable control module; a header coupled to the sealed body, the header comprising at least one connector assembly, each connector assembly defining a port with each connector assembly configured and arranged to receive a proximal portion of a lead inserted into the port, the header further comprising a plurality of contacts disposed within each connector assembly and configured and arranged to make contact with terminals disposed on a lead when the lead and terminals are received in the connector assembly and to electrically couple the terminals of the lead to the electronic subassembly; and a conductive shield disposed over at least a portion of the at least one connector assembly of the header, wherein the conductive shield is configured and arranged to hinder generation of current in the header or in a portion of a lead received in the header in response to application of an external radiofrequency (RF) or magnetic field, wherein the conductive shield comprises a substrate and a plurality of conductive stripes or conductive slats disposed on the substrate and arranged parallel to the at least one connector assembly, wherein the conductive shield is disposed over at least a portion of the header.
