Abstract: Waveguide neural interface devices and methods for fabricating such devices are provided herein. An exemplary interface device includes a neural device comprising an exterior neural device sidewall extending to a distal end portion of the neural device, an array of electrode sites supported by a first face of the neural device sidewall. The array includes a recording electrode site. The exemplary interface device further includes a waveguide extending along the neural device, the waveguide having a distal end to emit light to illuminate targeted tissue adjacent to the recording electrode site, and a light redirecting element disposed at the distal end of the waveguide. The light redirecting element redirects light traveling through the waveguide in a manner that avoids direct illumination of the recording electrode site on the first face of the neural device sidewall.

Abstract: A three-dimensional neural probe electrode array system is described. Planar probes are microfabricated and electrically connected to flexible micro-machined ribbon cables using a rivet bonding technique. The distal end of each cable is connected to a probe with the proximal end of the cable being customized for connection to a printed circuit board. Final assembly consists of combining multiple such assemblies into a single structure. Each of the two-dimensional neural probe arrays is positioned into a micro-machined platform that provides mechanical support and alignment for each array. Lastly, a micro-machined cap is placed on top of each neural electrode probe and cable assembly to protect them from damage during shipping and subsequent use. The cap provides a relatively planar surface for attachment of a computer controlled inserter for precise insertion into the tissue.
