MULTICHANNEL BRAIN PROBE
First Claim
1. A multichannel brain probe for recording and/or stimulating a subject, comprising:
- (a) an upper tubular shaft having an electrical connector attached at a first end and having a second upper shaft end;
(b) a lower tubular outer shaft having one end continuous with the second end of said upper shaft, the other end of said lower shaft having a sharpened point, said lower shaft having a plurality of holes in its outer surface;
(c) a plurality of conducting wires located inside said upper and lower continuous shafts, each wire having one end located in one of said holes flush with the outer surface of said lower shaft and the other end connected to an electrical connector interface.

Abstract
An intraoperative multichannel brain probe is presented. The brain probe has a cylindrical upper stainless steel section attached to a lower cylindrical section. In the lower section, an outer cylindrical tube surrounds a second insulating tube. Electrically recording/stimulating wires are placed between the outer tube and the second tube. Each wire has one end protruding out a hole in the outer tube. The other end of each wire is threaded through the entire probe and electrically connected to a recording or stimulating device through a connector system. A number of insulating tubes and electrodes located inside the second tube may also be part of the brain probe. Each inner electrode, typically two, is insulated from each other and from the second insulating tube by other insulating tubes. The combination of one or more wires and electrodes provides a multi-functional device. The brain probe is capable of providing multichannel stimulation and/or recording of brain functions and up to 128 individual electrode conducting sites.
