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 at the bone of a vestibular canal, wherein the extra-vestibular lead branch bifurcates at a distal end into a single array branch and a double array branch, wherein the single array branch has a stopper collar bent away at a first discrete angle (α) from a distal end of the single array branch to penetrate into a vestibular structure at the entry location; and an intra-vestibular electrode array bent away at a second discrete angle (β) 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, wherein the double array branch comprises a base hub and stopper bridge that form a forked shape with two intra-vestibular branch arrays located adjacent to each other, each intra-vestibular branch array having: i. one or more electrode contacts for delivering the stimulation signals to vestibular neural tissue, and ii. end bumps configured to limit post-surgical outward withdrawal of the intra-vestibular branch array, wherein the intra-vestibular electrode array of the single array branch and the intra-vestibular branch arrays of the double array branch are ergonomically pre-shaped to fit the anatomy of the vestibular structures. an extra-vestibular lead branch for carrying the stimulation signals from the stimulation module to a vestibular entry location at the bone of a vestibular canal, wherein the extra-vestibular lead branch bifurcates at a distal end into a single array branch and a double array branch, wherein the single array branch has a stopper collar bent away at a first discrete angle (α) from a distal end of the single array branch to penetrate into a vestibular structure at the entry location; and an intra-vestibular electrode array bent away at a second discrete angle (β) 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, wherein the double array branch comprises a base hub and stopper bridge that form a forked shape with two intra-vestibular branch arrays located adjacent to each other, each intra-vestibular branch array having: i. one or more electrode contacts for delivering the stimulation signals to vestibular neural tissue, and ii. end bumps configured to limit post-surgical outward withdrawal of the intra-vestibular branch array, i. one or more electrode contacts for delivering the stimulation signals to vestibular neural tissue, and ii. end bumps configured to limit post-surgical outward withdrawal of the intra-vestibular branch array, wherein the intra-vestibular electrode array of the single array branch and the intra-vestibular branch arrays of the double array branch are ergonomically pre-shaped to fit the anatomy of the vestibular structures.
