Patent number: 9327108Abstract: A flexible circuit electrode array device comprising: a polymer layer; wherein the polymer layer includes one or more metal traces, an electrode array; one or more bond pads; and the electrode array is located on the opposite side of the polymer layer. A method for backside processing of a flexible circuit electrode device, comprising: applying polymer film on a substrate; processing the front side; releasing the polymer film from substrate; flipping over the polymer film and fixing it onto the substrate; processing the backside; and final releasing of the polymer film from the substrate. Another aspect of the method involves backside processing of a flexible circuit electrode device, comprising: processing the front side without releasing the polymer; processing the backside by sacrificial substrate method, or by laser drilling method; and releasing the polymer film from the substrate.Type: GrantFiled: April 15, 2014Date of Patent: May 3, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Qingfang Yao, Jordan Matthew Neysmith, Neil Hamilton Talbot, James S Little, Robert J Greenberg

Patent number: 9314615Abstract: A flexible circuit electrode array with more than one layer of metal traces comprising: a polymer base layer; more than one layer of metal traces, separated by polymer layers, deposited on said polymer base layer, including electrodes suitable to stimulate neural tissue; and a polymer top layer deposited on said polymer base layer and said metal traces. 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, or cortical stimulation many 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.Type: GrantFiled: March 16, 2012Date of Patent: April 19, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Jordan Matthew Neysmith, Neil Hamilton Talbot, James Singleton Little, Brian V.

Patent number: 9308299Abstract: An implantable electrode and method for manufacturing the electrode wherein the electrode has a strong, adherent surface inert coating on a conductive coating on the electrode surface, which demonstrates an increase in surface area of at least five times when compared to smooth platinum of the same geometry. An iridium oxide coating may be formed on a platinum coating by a physical deposition process, such as sputtering. The process of electroplating the iridium oxide surface coating is accomplished by voltage control processes. A gradient coating of iridium oxide ranging in composition from essentially pure platinum to essentially pure iridium oxide is produced by sputtering.Type: GrantFiled: June 13, 2013Date of Patent: April 12, 2016Assignee: Second Sight Medical Products, Inc.Inventors: David D Zhou, Neil Hamilton Talbot, Robert J Greenberg

Publication number: 20150296626Abstract: Polymer materials make useful materials as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision. Regardless of which polymer is used, the basic construction method is the same. A layer of polymer is laid down. A layer of metal is applied to the polymer and patterned by wet etch to create electrodes and leads for those electrodes. The base polymer layer is activated. A second layer of polymer is applied over the metal layer and patterned to leave openings for the electrodes, or openings are created later by means such as laser ablation. Hence the array and its supply cable are formed of a single body.Type: ApplicationFiled: June 2, 2015Publication date: October 15, 2015Inventors: Robert J Greenberg, Jerry Ok, Jordan Matthew Neysmith, Brian V Mech, Neil Hamilton Talbot

Patent number: 9131863Abstract: The invention is directed to an implantable insulated electrical circuit that utilizes polyparaxylylene, preferably as Parylene, a known polymer that has excellent living tissue implant characteristics, to provide for chronic implantation of conductive electrical devices, such as stimulators and sensors. The device is thin, flexible, electrically insulated, and stable after long exposure to living tissue. Layers of Parylene may be combined with layers of a polymer, such as polyimide, to yield greater design flexibility in the circuit. Multiple electrical conduction layers may be stacked in the circuit to increase packing density.Type: GrantFiled: May 26, 2006Date of Patent: September 15, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Robert Greenberg, Neil Hamilton Talbot, Jerry Ok, Jordan Matthew Neysmith

Patent number: 9125290Abstract: 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, or cortical stimulation many 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: GrantFiled: January 2, 2014Date of Patent: September 1, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Robert Greenberg, Neil Hamilton Talbot, Jordan Matthew Neysmith, James S Little, Brian V Mech, Mark S Humayun, Dilek Guven, Anne Marie Ripley

Patent number: 8874239Abstract: A cochlear stimulation device comprising an electrode array designed to provide enhanced charge injection capacity necessary for neural stimulation. The electrode array comprises electrodes with high surface area or a fractal geometry and correspondingly high electrode capacitance and low electrical impedance. The resultant electrodes have a robust surface and sufficient mechanical strength to withstand physical stress vital for long term stability. The device further comprises wire traces having a multilayer structure which provides a reduced width for the conducting part of the electrode array. The cochlear prosthesis is attached by a grommet to the cochleostomy that is made from a single piece of biocompatible polymer. The device, designed to achieve optimum neural stimulation by appropriate electrode design, is a significant improvement over commercially available hand-built devices.Type: GrantFiled: November 7, 2008Date of Patent: October 28, 2014Assignee: Second Sight Medical Products, Inc.Inventors: Robert J.
