System And Method For Measuring And Fitting Spatio-Temporal Vision

View page
US Patent:
8428739, Apr 23, 2013
Filed:
Aug 26, 2009
Appl. No.:
12/548275
Inventors:
Ashish Ahuja - Los Angeles CA, US
Avraham Caspi - La Jolla CA, US
Jessy Dorn - Los Angeles CA, US
Robert J. Greenberg - Los Angeles CA, US
Kelly H. McClure - Simi Valley CA, US
Matthew J. McMahon - Washington DC, US
Devyani Nanduri - Los Angeles CA, US
Assignee:
Second Sight Medical Products, Inc. - Sylmar CA
International Classification:
A61N 1/18
US Classification:
607 53, 607 54
Abstract:
This system gives the experimenter great flexibility to present spatio-temporal stimulation patterns to a subject. A video configuration file (VCF) editor allows the experimenter to determine the electrical stimulation parameters for each electrode. A Pattern Stimulation software program allows direct stimulation of chosen patterns of electrodes, scaled by the subject's VCF, through a Graphical User Interface. The subject then responds by drawing the outline of the phosphene he or she perceives on a touchscreen. The Pattern Stimulation program saves all of the trial parameters and the parameters of an ellipse fit to their drawing, as well as a raw data file containing the input to the touchscreen is saved. After the experiment, offline image analysis can be performed to obtain a detailed quantitative description of the subject's percepts. Image descriptors can assigned to the touchscreen data; these image descriptors can be used to make formalized comparisons between various experimental conditions.

Encoding Of Size And Brightness Of Percepts In A Visual Prosthesis

View page
US Patent:
8527056, Sep 3, 2013
Filed:
Apr 29, 2011
Appl. No.:
13/097534
Inventors:
Devyani Nanduri - Los Angeles CA, US
Mark S. Humayun - Glendale CA, US
James D. Weiland - Valencia CA, US
Jessy Dorn - Los Angeles CA, US
Robert J. Greenberg - Los Angeles CA, US
Ione Fine - Seattle WA, US
Assignee:
Second Sight Medical Products, Inc. - Sylmar CA
International Classification:
A61N 1/00
US Classification:
607 53
Abstract:
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.

Method And Apparatus For Predicting And Controlling The Percepts Induced By A Visual Prosthesis

View page
US Patent:
8554327, Oct 8, 2013
Filed:
Nov 23, 2011
Appl. No.:
13/304128
Inventors:
Devyani Nanduri - Los Angeles CA, US
Ione Fine - Seattle WA, US
Robert J. Greenberg - Los Angeles CA, US
Jessy Dorn - Los Angeles CA, US
Assignee:
Second Sight Medical Products, Inc. - Sylmar CA
International Classification:
A61F 9/08
A61N 1/36
US Classification:
607 54
Abstract:
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.

Spatial Mapping For A Visual Prosthesis

View page
US Patent:
20080281377, Nov 13, 2008
Filed:
May 2, 2008
Appl. No.:
12/114657
Inventors:
Avraham Caspi - La Jolla CA, US
Jessy Dorn - Los Angeles CA, US
Matthew J. McMahon - Los Angeles CA, US
Robert J. Greenberg - Los Angeles CA, US
International Classification:
A61N 1/00
A61F 2/14
US Classification:
607 54, 623 41
Abstract:
A visual prosthesis and a method of operating a visual prosthesis are disclosed. Neural stimulation through electrodes is controlled by spatial maps, where a grouped or random association is established between the pixels of the acquired image and the electrodes. In this way distortions from the foveal pit and wiring mistakes in the implant can be corrected. Moreover, broken electrodes can be bypassed and a resolution limit can be tested, together with testing the benefit the patient receives from correct spatial mapping.

Visual Prosthesis Fitting Training And Assessment System And Method

US Patent:
20100249878, Sep 30, 2010
Filed:
Mar 26, 2010
Appl. No.:
12/748179
Inventors:
Matthew J. McMahon - Washington DC, US
Robert J. Greenberg - Los Angeles CA, US
Jessy Dorn - Los Angeles CA, US
Avraham I. Caspi - La Jolla CA, US
Kelly H. McClure - Simi Valley CA, US
International Classification:
A61F 9/08
A61N 1/36
US Classification:
607 54
Abstract:
The present invention is an improved fitting and training system for a visual prosthesis. A patient, using the visual prosthesis observes a display and indicates location, movement, shape or other properties of the display image to provide for improved fitting and training. In one embodiment, the patient uses a touch screen monitory which displays an image. The patient touches the monitor at the location where the patient perceives the image. The system then corrects the image to the location indicated by the patient. In another embodiment a patient observes an image moving across the touch screen monitor and indicates by moving their hand across the monitor which direction the believe the image is moving. The system can then rotate the image to match the image perceived by the patient.

Abstract:
A visual prosthesis and a method of operating a visual prosthesis are disclosed. Neural stimulation through electrodes is controlled by spatial maps, where a grouped or random association is established between the data points of the acquired data and the electrodes. In this way distortions from the foveal pit and wiring mistakes in the implant can be corrected. Moreover, broken electrodes can be bypassed and a resolution limit can be tested, together with testing the benefit the patient receives from correct spatial mapping.

Text Reading And Translation In A Visual Prosthesis

US Patent:
20130157229, Jun 20, 2013
Filed:
Dec 20, 2012
Appl. No.:
13/721685
Inventors:
Second Sight Medical Products, Inc. - San Fernando CA, US
Jessy D. Dorn - Los Angeles CA, US
Robert J. Greenberg - Los Angeles CA, US
Jordan Harris - Vancouver, CA
Jose Alain Sahel - Paris, FR
Assignee:
Second Sight Medical Products, Inc. - San Fernando CA
International Classification:
G09B 21/00
US Classification:
434112
Abstract:
The present invention is a visual prosthesis which restores partial vision to patients blinded by outer retinal degeneration. While visual prosthesis users have achieved remarkable visual improvement to the point of reading letters and short sentences, the reading process is still fairly cumbersome. In the present invention the visual prosthesis is adapted to stimulate visual braille as a sensory substitution for reading written letters and words. The visual prosthesis system, used in the present invention, includes a 10×6 electrode array implanted epiretinally, a tiny video camera mounted on a pair of glasses, and a wearable computer that processes the video and determines the stimulation current of each electrode in real time.
