Patent number: 9861820Abstract: The present invention consists of an implantable device with a hermetic electronics package that houses electronics. The hermetic package is attached to a flexible circuit electrode array having its electrodes arranged in a trapezoidal electrode array field that is suitable to stimulate the visual cortex. The hermetic electronics package is provided with a fixation structure that secures, protects and dissipates heat from the electronics package. The entire implantable device can be entirely implanted within the head.Type: GrantFiled: May 13, 2016Date of Patent: January 9, 2018Assignee: Second Sight Medical Products, Inc.Inventors: Robert J.

Patent number: 9526894Abstract: 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.Type: GrantFiled: July 6, 2015Date of Patent: December 27, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Robert Greenberg, Avraham Caspi, Jessy Dorn, Matthew J McMahon

Patent number: 8554327Abstract: 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: November 23, 2011Date of Patent: October 8, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Devyani Nanduri, Ione Fine, Robert 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.

Patent number: 8428739Abstract: 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.Type: GrantFiled: August 26, 2009Date of Patent: April 23, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Ashish Ahuja, Avraham Caspi, Jessy Dorn, Robert J.

Publication number: 20100249878Abstract: 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.Type: ApplicationFiled: March 26, 2010Publication date: September 30, 2010Inventors: Matthew J. McMahon, Robert J. Greenberg, Jessy Dorn, Avraham I. Caspi, Kelly H. McClure
