Patent number: 8639344Abstract: 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: April 28, 2006Date of Patent: January 28, 2014Assignee: Second Sight Medical Products, Inc.Inventors: Robert Jay Greenberg, Neil Hamilton Talbot, Jordan Matthew Neysmith, James Singleton Little, Brian V.

Patent number: 8588937Abstract: An electrode array attached to neural tissue, such as the retina, necessarily has graded pressure exerted on the tissue, with higher pressure near the attachment point. Greater pressure improves contact between the electrodes and neural tissue while too much pressure may damage neural tissue. Hence it is advantageous to obtain equal pressure across the array field. In the present invention a central attachment point in the electrode field applies the most even pressure. Further, multiple and selective attachment points may be additionally provided on an electrode array allowing a surgeon to select the attachment points providing the best electrode tissue contact.Type: GrantFiled: January 27, 2012Date of Patent: November 19, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Robert J.
