Patent number: 9597495Abstract: The invention is a method of identifying a preferred location for an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject and array location to array location. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the preferred location. Alternatively, electrode height may be measured directly to predict the preferred location.Type: GrantFiled: April 20, 2012Date of Patent: March 21, 2017Assignee: Second Sight Medical Products, Inc.Inventors: Robert J. Greenberg, Jone Fine, Arup Roy, Matthew J. McMahon, Mark S. Humayun, James David Welland, Alan M. Horsager, Dao Min Zhou, Amy Hines, Sumit Yadav, Rongqing Dai
