Furcated sensing and stimulation lead
First Claim
1. A furcated medical electrical lead adapted to be at least partially implanted in a human patient, the lead comprising:
- a proximal portion having a lead connection area;
a furcated distal portion having a plurality of separate distal end segments; and
a body interconnecting the proximal portion and the distal portion;
wherein each of the separate distal end segments comprises at least one electrode in communication with the lead connection area of the proximal portion.

Abstract
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.

34. A method for using a furcated medical electrical lead in conjunction with a neurological diagnostic or treatment apparatus, wherein the lead has a distal portion with a plurality of separate distal end segments, the method comprising the steps of:
-
accessing a patient'"'"'s cortex by forming an opening in the patient'"'"'s cranium;
selecting a plurality of electrode sites in the patient'"'"'s cortex corresponding to the plurality of distal end segments;
passing the distal portion of the lead through the opening in the patient'"'"'s cranium;
inserting the plurality of distal end segments into the respective plurality of electrode sites; and
connecting the lead to the neurological diagnostic or treatment apparatus via a lead connection area at a proximal portion of the lead.
