1. A vestibular stimulation electrode lead for conducting electrical stimulation signals generated by an implanted vestibular stimulation module, the electrode lead comprising: an extra-vestibular lead branch for carrying the stimulation signals from the stimulation module to a vestibular entry location; a stopper collar 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; and an intra-vestibular electrode array bent away at a second discrete angle from the stopper collar and having 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.
