A furcated medical electrical lead for neurological applications has a distal portion having a plurality of distal end segments, each of which bears at least one distal electrode for electrographic sensing or electrical stimulation. The furcated configuration allows each distal end segment to be implanted in a different site in the patient's brain. In contrast to surface strip or grid electrodes, shallow implantation reduces the probability that any of the electrodes will move away from the surface of the brain due to atrophy or other phenomena. |
