METHODS AND SYSTEMS FOR ELECTRICAL STIMULATION INCLUDING A SHIELDED LEAD
First Claim
1. An electrical stimulation lead, comprising:
- at least one lead body having a distal end portion, a proximal end portion, and an outer surface, each of the at least one lead body comprising a lead jacket forming at least a portion of the outer surface of the lead body, the lead jacket comprising a non-conductive lead jacket material;
a plurality of electrodes disposed along the distal end portion of the at least one lead body;
a plurality of terminals disposed along the proximal end portion of the at least one lead body;
a plurality of conductors extending within the at least one lead body, each conductor of the plurality of conductors electrically coupling at least one of the plurality of terminals to at least one of the plurality of electrodes, wherein the plurality of conductors comprises at least one first conductor and at least one second conductor, wherein the at least one first conductor is coiled around the at least one second conductor; and
a conductive RF shield disposed between at least a portion of the lead jacket and around at least a portion of each of the plurality of conductors.

Abstract
An electrical stimulation lead includes at least one lead body having a distal end portion, a proximal end portion, and an outer surface. Each lead body has a lead jacket. The lead also includes electrodes disposed along the distal end portion of the at least one lead body; terminals disposed along the proximal end portion of the at least one lead body; and conductors extending within the at least one lead body to electrically couple the terminals to the electrodes. The conductors include at least one first conductor and at least one second conductor with the at least one first conductor coiled around the at least one second conductor. The lead further includes a conductive RF shield disposed between at least a portion of the lead jacket and around at least a portion of each of the conductors. A lead extension can be similarly constructed.
