Abstract:
1. An apparatus for treating the brain, comprising: a first fluid delivery device including a distal end sized and shaped for placement at a first target site between a dura mater and a pia mater of the brain, the first fluid delivery device including a first fluid lumen extending along a first fluid lumen path from a first fluid lumen proximal end to a first fluid lumen distal end open to a first outlet opening in the distal end of the first fluid delivery device to deliver fluids to a first target location and a second fluid lumen extending through the first fluid delivery device along a second fluid lumen path from a second fluid lumen proximal end to a second fluid lumen distal end open to the first outlet opening, wherein the first fluid lumen path is separated from the second fluid lumen path; and a first microelectrode extending from a microelectrode proximal end to a first distal tip, the first microelectrode being mounted within the distal end of the first fluid delivery device for movement between an insertion position in which a first distal tip of the first microelectrode is received within the first fluid delivery device and a deployed position in which the first microelectrode extends out of the first fluid delivery device with the first distal tip thereof penetrating the pia mater to a first electrode target position in the cerebral cortex, wherein the first microelectrode is movable independently of the first fluid lumen.
