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.

Patent number: 9308368Abstract: A visual prosthesis must convey luminance information across a range of brightness levels to accurately represent a visual scene. Thus, the brightness of phosphenes produced by individual electrodes should scale appropriately with luminance, and the same luminance should produce equivalently bright phosphenes across the entire electrode array. Given that the function relating current to brightness varies across electrodes, it is necessary to develop a fitting procedure that will permit brightness to be equated across an entire array. A visual prosthesis that generates stimuli by performing a brightness fitting that normalizes brightness across electrodes is described.Type: GrantFiled: March 6, 2014Date of Patent: April 12, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Scott H Greenwald, Matthew J McMahon, Ione Fine

Patent number: 9211404Abstract: Here we present the first model that quantitatively predicts the apparent spatial position and shape of percepts elicited by retinal electrical stimulation in humans based on the known anatomy of the retina. This model successfully predicts both the shape of percepts elicited by single electrode stimulation and the shape and relative positions of percepts elicited by multiple electrode stimulation. Model fits to behavioral data show that sensitivity to electrical stimulation is not confined to the axon initial segment, but does fall off rapidly with the distance between stimulation and the initial segment. Using the model, it is possible to compensate, preferably with a look up table, to match percepts to a desired image.Type: GrantFiled: August 11, 2014Date of Patent: December 15, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Devyani Nanduri, Ione Fine, Robert J Greenberg, Jessy D Dorn

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: 9078739Abstract: The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual patient. The perceptual response to electrical neural stimulation varies from patient to patient and The response to electrical neural stimulation varies from patient to patient and the relationship between current and perceived brightness is often non-linear. It is necessary to determine this relationship to fit the prosthesis settings for each patient. It is advantageous to map the perceptual responses to stimuli. The method of mapping of the present invention is to provide a plurality of stimuli that vary in current, voltage, pulse duration, frequency, or some other dimension; measuring and recording the response to those stimuli; deriving a formula or equation describing the map from the individual points; storing the formula; and using that formula to map future stimulation.Type: GrantFiled: September 10, 2010Date of Patent: July 14, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Robert Jay Greenberg, Ione Fine, Arup Roy, Matthew J.

Patent number: 8527056Abstract: Methods of electrically stimulating percepts in a patient with a visual prosthesis are discussed. Changes in amplitude of stimulation increase both the perceived brightness and the perceived size of the precept. Changes in frequency of stimulation change the perceived brightness without altering the perceived size of the percept. Hence, a source image may be mapped to a combination of amplitude and frequency that best induces the desired image.Type: GrantFiled: April 29, 2011Date of Patent: September 3, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Devyani Nanduri, Mark S.
