Patent number: 9044590Abstract: 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 to create electrodes and leads for those electrodes. 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: August 8, 2013Date of Patent: June 2, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Robert J Greenberg, Jerry Ok, Jordan Matthew Neysmith, Brian V Mech, Neil Hamilton Talbot
