Patent number: 9258902Abstract: The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package, that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a plated rivet-shaped connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.Type: GrantFiled: October 16, 2014Date of Patent: February 9, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Robert J Greenberg, Neil H Talbot, Jerry Ok, Jordan M Neysmith, David D Zhou

Patent number: 9205269Abstract: It is critical in an inductively link medical implant, such as a visual prosthesis or other neural stimulator, to adjust the external coil to a location to maximize communication between the external coil and internal coil. Converting the signal strength between the coils to a signal easily discernible by a clinician, preferably an audible tone, facilitates the adjustment of the external coil to a preferred location.Type: GrantFiled: May 26, 2015Date of Patent: December 8, 2015Assignee: Second Sight Medical Products, Inc.Inventors: David Marsh, Kelly H McClure, Robert J Greenberg, Walter P Little, Jordan M Neysmith, Brian Coley, Scott Loftin

Patent number: 9161704Abstract: The invention is directed to a method of making 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: February 18, 2015Date of Patent: October 20, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Robert J Greenburg, Jordan M Neysmith, Neil H Talbot, Jerry Ok

Patent number: 8510939Abstract: 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: GrantFiled: October 26, 2007Date of Patent: August 20, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Robert J. Greenberg, Matthew J. McMahon, James Singleton Little, Kelly H. McClure, Brian V. Mech, Neil Hamilton Talbot, Jordan M. Neysmith
