Patent number: 9700724Abstract: An apparatus and method for electrical charge balancing when generating a stimulus during functional neural stimulation is presented. A stimulus pulse is generated (cathodic or anodic), and after a selected delay a charge compensating pulse is generated of an opposite polarity. The electrode circuit discontinuously examines electrode voltage after termination of the stimulus pulse, and utilizes this voltage to determine how long to extend the width of the charge compensating pulse. The electrode circuit thus performs accurate electrical charge cancellation to remove residual charges from the electrode by precisely controlling pulse width for an opposing polarity compensating pulse that need not have the same current level as the stimulus pulse.Type: GrantFiled: August 23, 2015Date of Patent: July 11, 2017Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Wentai Liu, Richard Hill, Yi-Kai Lo, Kuanfu Chen

Patent number: 9642552Abstract: The invention comprises an elongated device adapted for insertion, including self-insertion, through the body, especially the skull. The device has at least one effector or sensor and is configured to permit implantation of multiple functional components through a single entry site into the skull by directing the components at different angles. The device may be used to provide electrical, magnetic, and other stimulation therapy to a patient's brain. The lengths of the effectors, sensors, and other components may completely traverse skull thickness (at a diagonal angle) to barely protrude through to the brain's cortex. The components may directly contact the brain's cortex, but from there their signals can be directed to targets deeper within the brain. Effector lengths are directly proportional to their battery size and ability to store charge. Therefore, longer angled electrode effectors not limited by skull thickness permit longer-lasting batteries which expand treatment options.Type: GrantFiled: March 11, 2015Date of Patent: May 9, 2017Inventor: Sherwin Hua
