Patent number: 9788432Abstract: 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: GrantFiled: June 2, 2015Date of Patent: October 10, 2017Assignee: Second Sight Medical Products, Inc.Inventors: Robert J Greenberg, Jerry Ok, Jordan Matthew Neysmith, Brian V Mech, Neil Hamilton Talbot

Patent number: 9656059Abstract: 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: October 17, 2014Date of Patent: May 23, 2017Assignee: Second Sight Medical Products, Inc.Inventors: Robert J Greenberg, David D Zhou, Jordan Matthew Neysmith, Kelly H McClure, Jianing Wei, Neil H Talbot, James S Little

Patent number: 9427582Abstract: 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: GrantFiled: November 4, 2014Date of Patent: August 30, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Robert J Greenberg, Matthew J McMahon, Jordan Matthew Neysmith, James S Little, Neil Hamilton Talbot, Kelly H McClure, Brian V Mech
