Patent Images
1. An electrical lead comprising:
- a cylindrical lead body having an outer surface, a proximal end, a distal end and a longitudinal axis extending therethrough;
at least one row of directional electrodes disposed along the longitudinal axis of the lead body including at least one directional electrode disposed on the distal end of the outer surface of the cylindrical lead body; and
at least one unitary electrode disposed along the longitudinal axis of the body, with at least one unitary electrode having at least one exposed portion on the distal end of the outer surface of the cylindrical lead body and at least one recessed portion.

Abstract
Leads having directional electrodes thereon. Also provided are leads having directional electrodes as well as retention ledges to secure the electrodes to the leads. Also provided are leads with directional electrodes where all the electrodes have the same surface area. Methods of manufacturing leads and methods of treating conditions and selectively stimulating regions of the nervous system are also provided.
