Publication number: 20170326382Abstract: 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.Type: ApplicationFiled: May 8, 2017Publication date: November 16, 2017Applicant: NeuroNexus Technologies, Inc.Inventors: John P.

Patent number: 7790493Abstract: Disclosed herein is a method of fabricating a device having a microstructure. The method includes forming a connector on a semiconductor substrate, coating the connector with a polymer layer, and immersing the semiconductor substrate and the coated connector in an etchant solution to form the microstructure from the semiconductor substrate and to release the coated connector and the microstructure from the semiconductor substrate such that the microstructure remains coupled to a further element of the device via the coated connector. In some cases, the microstructure is defined by forming an etch stop in the semiconductor substrate, and the microstructure and the semiconductor substrate are coated with a polymer layer, which may then be selectively patterned. The microstructure may then be released from the semiconductor substrate in accordance with the etch stop.Type: GrantFiled: May 25, 2006Date of Patent: September 7, 2010Assignee: The Regents of the University of MichiganInventors: Kensall D.
