Electrical stimulation leads and systems having a RF shield along at least the lead and methods of making and using
First Claim
1. An electrical stimulation system, comprising:
- a lead having distal end portion, a proximal end portion, and a longitudinal length, the lead comprising a plurality of electrodes disposed along the distal end portion of the lead, a plurality of terminals disposed along the proximal end portion of the lead, and a plurality of conductors coupling the plurality of terminals to the plurality of electrodes;
a control module coupleable to the lead and comprising a housing and an electronic subassembly disposed in the housing, wherein the control module comprises a port configured to receive the proximal end portion of the lead; and
a continuous conductive RF shield comprising a first portion extending along a portion of the lead and a second portion configured and arranged to form a perimeter band disposed around the housing of the control module, wherein, when the end portion of the lead is received in the port of the control module, the first portion or the continuous conductive RF shield extends away from the control module along the portion of the lead.

Abstract
An electrical stimulation system includes a lead or lead extension; a control module coupleable to the lead or lead extension; and a continuous conductive RF shield having a first portion extending along at least a portion of the lead and a second portion configured and arranged to form a perimeter band disposed around the housing of the control module. Alternatively, an electrical stimulation lead or lead extension includes a body; first contacts disposed along the distal end portion of the body; second contacts disposed along the proximal end portion of the body; a conductive RF shield disposed over, and extending along, at least a portion of the body; and a non-conductive jacket disposed over the conductive RF shield. The non-conductive jacket defines at least one window which exposes a portion of the conductive RF shield radially beneath the at least one window.
