Systems and methods for making and using electrical stimulation systems to reduce RF-induced tissue heating
First Claim
1. An electrical stimulation lead, comprising:
- a lead body having a distal end, a proximal end, and a longitudinal length;
a plurality of electrodes disposed along the distal end of the lead body;
a plurality of terminals disposed along the proximal end of the lead body;
a non-conducting core extending along lead body; and
a plurality of conductors extending along the lead body to electrically couple the plurality of electrodes to the plurality of terminals, wherein the plurality of conductors comprises a first conductor and a second conductor arranged along the core with a non-conducting gap between the first and the second conductors,wherein each of the first and the second conductors comprises an inner conductor portion with a first electrical resistivity and an outer conductor portion having a second electrical resistivity that is at least twice the first electrical resistivity, wherein the outer conductor portion is disposed exclusively radially outward from the inner conductor portion.

Abstract
An electrical stimulation lead includes a lead body having a distal end, a proximal end, and a longitudinal length; electrodes disposed along the distal end of the lead body; terminals disposed along the proximal end of the lead body; a non-conducting core extending along lead body; and conductors extending along the lead body to electrically couple the electrodes to the terminals. The conductors include a first conductor and a second conductor arranged along the core with a non-conducting gap between the first and the second conductors. Each of the first and the second conductors includes an inner conductor portion with a first electrical resistivity and an outer conductor portion having a second electrical resistivity that is at least twice the first electrical resistivity. The outer conductor portion is disposed exclusively radially outward from the inner conductor portion.
