ABSTRACT:
A neurological epidural lead is disclosed having an extension that extends distally beyond the most distal electrode. The length of the extension corresponds to the length of one ore more vertebral segments. The lead is placed in the epidural space so that the electrodes are positioned as desired. In positioning the electrodes, the extension passes through at least one area where the epidural space between the dura and the spinal canal wall is very narrow because the dura and spinal canal wall are in contact. As a result, the extension is held in place by contact with both the dura and spinal canal wall so that lateral lead migration of the electrodes is minimized.
