Patent number: 10780272Abstract: The present invention is a fitting system with a graphical interface with specific interface screens for specific functions. Methods and devices for fitting a visual prosthesis are described. In one of the methods, threshold levels and maximum levels for the electrodes of the prosthesis are determined and a map of brightness to electrode stimulation levels is later formed. A fitting system for a visual prosthesis is also discussed, together with a computer-operated system having a graphical user interface showing visual prosthesis diagnostic screens and visual prosthesis configuration screens.Type: GrantFiled: August 20, 2012Date of Patent: September 22, 2020Assignees: Second Sight Medical Products, Inc., Doheny Eye InstituteInventors: Matthew J. McMahon, Arup Roy, Scott Greenwald, Ione Fine, Alan Matthew Horsager, Avraham I. Caspi, Kelly Hobart McClure, Robert Jay Greenberg

Patent number: 9095710Abstract: The present invention is a visual prosthesis for stimulating visual neurons to create the perception of light. The visual prosthesis electrically stimulating the retina with implanted electrodes exhibits interaction between electrodes stimulated closely together in both space and time. The visual prosthesis of the present invention includes means for determining a minimum distance at which spatiotemporal interactions occur, determining a minimum time at which spatiotemporal interactions occur, and avoiding stimulation of electrodes within the minimum distance during the minimum time. The minimum are ideally established for each individual patient. Alternatively, approximate minimums have been established by the applicants at 2 mm and 1.8 milliseconds.Type: GrantFiled: November 27, 2013Date of Patent: August 4, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Alan Matthew Horsager, Geoffrey M Boynton, Robert J Greenberg, Ione Fine

Patent number: 9061150Abstract: The present invention is a saliency-based apparatus and methods for visual prostheses. A saliency-based component processes video data output by a digital signal processor before the video data are input to the retinal stimulator. In a saliency-based method, an intensity stream is extracted from an input image, feature maps based on the intensity stream are developed, plural most salient regions of the input image are detected and one of the regions is selected as a highest saliency region.Type: GrantFiled: March 6, 2008Date of Patent: June 23, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Robert J. Greenberg, Alan Matthew Horsager, Mark S. Humayun, Kelly H. McClure, Matthew J. McMahon, Peter Meilstrup, Neha Jagdish Parikh, Arup Roy, James D. Weiland, Chunhong Zhou
