A vestibular electrode is described that is for implantation into a vestibular semi-circular canal. An intra-labyrinthine electrode carrier with a C-shaped cross-section has an inner concave surface and an outer convex surface, and is configured to fit through an electrode opening in an outer surface of the bony labyrinth into the perilymph fluid without breaking the membranous labyrinth so as to fit the inner concave surface of the electrode carrier adjacent to the membranous labyrinth and the outer convex surface adjacent to the bony labyrinth. There are one or more electrode contacts on a surface of the electrode carrier that are configured for electrical interaction with adjacent neural tissue.
