摘要：
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.
