Patent number: 11224746Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation, which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes, as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.Type: GrantFiled: July 18, 2019Date of Patent: January 18, 2022Assignee: Second Sight Medical Products, Inc.Inventors: Robert Jay Greenberg, Kelly Hobart McClure, James S.

Patent number: 9095709Abstract: A visor for retinal stimulation of visually impaired. The visor comprises a frame, an external coil, a camera and a mounting system. A connector allows the external coil to be positioned along a first direction. A sliding device allows the external coil to be positioned along a second direction. Positioning of the visor on a subject's nose allows the external coil to be positioned along a third direction. Positioning of the external coil along the first, second or third direction is useful to maximize coupling RF coupling between the external coil and an internal coil implanted on a subject wearing the visor.Type: GrantFiled: August 15, 2007Date of Patent: August 4, 2015Assignee: Second Sight Medical Products, Inc.Inventors: Kelly H.
