Abstract: A brain stimulation lead for precise delivery of electrical stimuli to a small dense brain target, and method of positioning such lead optimally in the patient's brain, is provided. The lead has a distal end portion which is substantially tubular or cylindrical along a longitudinal axis, and has a plurality of electrodes characterized by a diagonal geometry, permitting a greater number of electrodes to be provided within a very small lineal distance, e.g. 10 mm or even 5 mm. In a preferred embodiment, three ring electrodes are positioned on the distal end portion, each at a common angle of about 45 degrees and each extending only about 180.degree. around the lead body. The ring segment electrodes are about 0.5 mm in axial length, and have a separation of about 0.5 mm. The lead also has a tip electrode with a substantially spherical distal edge, and a proximal diagonal edge having the same angle as the ring segment electrodes.
