Publication number: 20130289688Abstract: Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, and cortical stimulation, and many related purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow. Common flexible circuit fabrication techniques generally require that a flexible circuit electrode array be made flat. Since neural tissue is almost never flat, a flat array will necessarily apply uneven pressure. Further, the edges of a flexible circuit polymer array may be sharp and cut the delicate neural tissue. It is advantageous that the array edges not contact tissue.Type: ApplicationFiled: June 20, 2013Publication date: October 31, 2013Inventors: Robert J. Greenberg, Mathew J.

It has at least one electrode that makes contact with the scleral surface of the eye, the electrode typically being activated by an electrical stimulator. The device produces electrical pulses which pass through the electrodes on the scleral surface of the eye, to activate the retina of the eye, which causes the patient to experience improved vision, visual sensations or the prevention of deterioration of vision. By this means, sight can be restored or improved where patients have disorders of their retina or other parts of their visual system.Type: GrantFiled: May 23, 2005Date of Patent: January 25, 2011Assignee: Sydney Biotech Pty.

Patent number: 7565202Abstract: The present invention is a system for mapping a high resolution image to a lower resolution electrode array and, by applying varying stimulus to neighboring electrodes, creating a perceived image greater in resolution than the electrode array. The invention is applicable to a wide range of neural stimulation devices including artificial vision and artificial hearing. By applying a sub-threshold stimulus to two neighboring electrodes where the sum of the stimuli is above the threshold of perception, a perception is created in neural tissue between the two electrodes. By adjusting the stimulus on neighboring electrodes, the location of stimulation can be altered. Further, noise can be applied to the stimulating electrode or its neighboring electrodes to reduce the threshold of stimulation.Type: GrantFiled: January 31, 2003Date of Patent: July 21, 2009Assignee: Second Sight Medical Products, Inc.Inventors: Robert J. Greenberg, Richard Williamson

Patent number: 7493169Abstract: A method of automatically adjusting an electrode array to the neural characteristics of an individual patient is disclosed. By recording neural response to a predetermined input stimulus, one can alter that input stimulus to the needs of an individual patient. A minimum input stimulus is applied to a patient, followed by recording neural response in the vicinity of the input stimulus. By alternating stimulation and recording at gradually increasing levels, one can determine the minimum input that creates a neural response, thereby identifying the threshold stimulation level. One can further determine a maximum level by increasing stimulus until a predetermined maximum neural response is obtained.Type: GrantFiled: August 2, 2006Date of Patent: February 17, 2009Assignee: Second Sight Medical Products, Inc.Inventors: Robert Greenberg, Richard Williamson

Publication number: 20080275527Abstract: Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, and cortical stimulation, and many related purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow. Common flexible circuit fabrication techniques generally require that a flexible circuit electrode array be made flat. Since neural tissue is almost never flat, a flat array will necessarily apply uneven pressure. Further, the edges of a flexible circuit polymer array may be sharp and cut the delicate neural tissue. By applying the right amount of heat to a completed array, a curve can be induced.Type: ApplicationFiled: October 26, 2007Publication date: November 6, 2008Inventors: Robert J. Greenberg, Matthew J.
