Electrical stimulation paddle leads and methods of making and using
First Claim
1. An electrical stimulation lead, comprising:
- a paddle body comprising a non-conductive, biocompatible material;
at least one lead body having a distal end, a proximal end, and a longitudinal length, the distal end of each of the at least one lead bodies coupled to the paddle body;
a plurality of electrically conductive fixation elements embedded within the paddle body so that the non-conductive material of the paddle body surrounds and is in contact with a plurality of surfaces of each of the fixation elements;
a plurality of electrodes disposed on the paddle body, each electrode comprising a stimulating element with an exposed stimulation surface and a piercing element extending from the stimulating element into the paddle body and making contact with at least one of the plurality of fixation elements, wherein the piercing element comprises a post that engages the at least one of the fixation elements to physically and electrically couple the post to the at least one of the fixation elements;
a plurality of terminals disposed along the proximal ends of each of the at least one lead bodies; and
a plurality of conductor wires, each conductor wire of the plurality of conductor wires electrically coupling each of the plurality of terminals to at least one of the plurality of electrodes.

Abstract
An electrical stimulation lead includes a paddle body, at least one lead body having a distal end, a proximal end, and a longitudinal length with the distal end of the lead body coupled to the paddle body. The lead further includes fixation elements and electrodes. The fixation elements are disposed entirely within the paddle body and the electrodes are disposed on the paddle body. Each of the electrodes includes a stimulating element with an exposed stimulation surface, and a piercing element extending from the stimulating element into the paddle body and making contact with at least one of the fixation elements. Further, the lead includes terminals disposed along the proximal end of the lead body and conductor wires electrically coupling the electrodes to the terminals. In addition, methods of making stimulation leads using sacrificial portions of electrodes are presented.
