Methods and systems for electrical stimulation including a shielded sheath
First Claim
1. An electrical stimulation system, comprising:
- an electrical stimulation lead comprising at least one lead body having a distal end portion and a proximal end portion, 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, and a plurality of conductors electrically coupling the plurality of terminals to the plurality of electrodes; and
a first sheath defining a sheath lumen and configured and arranged to slide over and along the electrical stimulation lead to cover a selected portion of the electrical stimulation lead, the first sheath comprising a flexible sheath body and an elongate RF shield disposed within the sheath body and extending along the first sheath, wherein the first sheath is configured and arranged to radially stretch to cover a connector of a lead extension which has a diameter greater than a diameter of the electrical stimulation lead.

Abstract
An electrical stimulation system includes an electrical stimulation lead with at least one lead body, electrodes disposed along the distal end portion of the lead body(ies), terminals disposed along the proximal end portion of the lead body(ies), and conductors electrically coupling the terminals to the electrodes. The electrical stimulation system also includes a lead extension coupleable to the electrical stimulation lead. The lead extension includes a connector for receiving the proximal end portion of the electrical stimulation lead. The electrical stimulation system further includes a sheath defining a sheath lumen to slidingly receive a portion of the electrical stimulation lead or a portion of the lead extension or a portion of both the electrical stimulation lead and the lead extension. The sheath includes a flexible sheath body and an elongate RF shield disposed within the sheath body and extending along the sheath.
