MICROFABRICATED NEUROSTIMULATION DEVICE
First Claim
1. An implantable neurological device, comprising:
- a support tube;
a cylindrical member coupled with the support tube, the cylindrical member comprising a distal end, a proximal end, and an internal lumen; and
a plurality of circumferential, segmented electrodes spaced along a longitudinal axis of the cylindrical member, each of the plurality of circumferential, segmented electrodes comprising at least three microelectrodes at a common location along the longitudinal axis.

Abstract
Described herein are microelectrode array devices, and methods of fabrication and use of the same, to provide highly localized and efficient electrical stimulation of a neurological target. The device includes multiple microelectrode elements arranged along an elongated probe shaft. The microelectrode elements are dimensioned and shaped so as to target individual neurons, groups of neurons, and neural tissue as may be located in an animal nervous system, such as deep within a human brain. Beneficially, the neurological probe can be used to facilitate location of the neurological target and remain implanted for long-term monitoring and/or stimulation.
