Implantable vestibular prosthesis

摘要

An implantable nerve stimulation device has a sensor system, a data processor in communication with the sensor system, and a nerve stimulation system in communication with the data processor and constructed to provide electrical stimulation to at least one branch of at least one vestibulocochlear nerve. The nerve stimulation system includes an electrode array that has a first plurality of electrodes structured to be surgically implanted in electrical communication with a superior branch of the vestibular nerve, a second plurality of electrodes structured to be surgically implanted in electrical communication with a horizontal branch of the vestibular nerve, a third plurality of electrodes structured to be surgically implanted in electrical communication with a posterior branch of the vestibular nerve, and a common erus reference electrode structured to be surgically implanted into a common eras of the vestibular labyrinth.
