Patent number: 10258793Abstract: An embodiment in accordance with the present invention provides a device and method to deliver direct ionic current safely to target neural tissue, while also eliminating interruptions in the output of the device that can result from the non-ideal operation of the valves used to control the current flow in the device. The device includes two valve-operated systems that work in tandem. The first and second current producing systems are configured to be used together in order to eliminate the periodic interruptions in current flow. In use, one system drives current through the target tissue, while the other system closes all of the valves first and then opens its valves in sequence. This intermediate step of closing all of the valves prevents unintended current shunts through either system. The device also includes two conductors to direct the flow of direct current into the target tissue.Type: GrantFiled: February 13, 2017Date of Patent: April 16, 2019Assignee: The Johns Hopkins UniversityInventors: Gene Yevgeny Fridman, Charles Coleman Della Santina

Patent number: 9289598Abstract: A vestibular stimulation electrode lead is described for conducting electrical stimulation signals generated by an implanted vestibular stimulation module. An extra-vestibular lead branch carries the stimulation signals from the stimulation module to a vestibular entry location. A stopper collar is bent away at a first discrete angle from a distal end of the extra-vestibular lead branch to penetrate into a vestibular structure at the entry location. An intra-vestibular electrode array is bent away at a second discrete angle from the stopper collar and has an outer surface with one or more electrode contacts for delivering the stimulation signals to vestibular neural tissue at a target location within the vestibular structure. The first and second discrete angles form a geometry of the stopper collar and intra-vestibular electrode array that limits insertion of the intra-vestibular electrode array beyond the target location within the vestibular structure.Type: GrantFiled: February 14, 2014Date of Patent: March 22, 2016Assignees: MED-EL Elektromedizinische Geraete GmbH, The Johns Hopkins UniversityInventors: Charles Coleman Della Santina, Andreas Marx

Patent number: 8751012Abstract: A novel vestibular implant system is described. An implantable vestibular stimulator provides vestibular stimulation signals to stimulate target neural tissue for vestibular sensation by a patient. One or more motion sensors are controllably powered by the vestibular implant system and develop a motion signal reflecting head motion of an implant patient. The vestibular stimulator includes at least two different operating modes: i. a sensor controlled mode wherein the motion sensor is powered and the vestibular stimulation signal is developed as a dependent function of the motion signal, and ii. a sensor independent mode wherein the motion sensor is unpowered and the vestibular stimulation signals, if any, are developed independently of the motion signal.Type: GrantFiled: January 17, 2013Date of Patent: June 10, 2014Assignee: MED-EL Elektromedizinische Geraete GmbHInventors: Andreas Jäger, Carolyn Garnham, Roland Hessler, Martin Zimmerling, Charles Coleman Della Santina, Gene Fridman
