<p>An implantable electrical stimulation lead includes a lead body having a proximal end portion, a distal end portion, a distal tip, a longitudinal length, and a longitudinal surface. Segmented tip electrodes are disposed circumferentially about the distal tip of the lead body and are electrically-isolated from each other. Each segmented tip electrode has an inner surface and an opposing outer stimulating surface exposed along the longitudinal surface of the lead body. A portion of the lead body is disposed against the inner surfaces of each of the segmented tip electrodes and circumferentially between each of the segmented tip electrodes. A non-tip electrode is disposed along the distal end portion of the lead body proximal to the segmented tip electrodes. Terminals are disposed along the proximal end portion of the lead body. Conductors electrically couple the terminals to the segmented tip electrodes and to the non-tip electrode.</p> |
