An implantable fenestration electrode delivers electrical stimulation signals for treatment of Meniere's disease. An electrode lead contains one or more signal wires for carrying a stimulation signal. An electrode tip at a terminal end of the electrode lead is configured for placement within a fenestration opening in an outer surface of a bony labyrinth of a patient with Meniere's disease without penetrating or impairing intra-labyrinthine membranes or neural tissue, and is adapted to deliver the stimulation signal via intra-labyrinthine fluid to the intra-labyrinthine neural tissue.
