Design of neuromodulation electrodes for methods to treat pelvic floor disorders, such as urinary and/or faecal incontinence, by means of electrical stimulation of the left and/or right branches of the dorsal genital nerves, or pudendal nerve, using a highly flexible electrode unit to obtain stable and comfortable contact with the cutaneous tissue or mucous membrane at or near the glans of the clitoris, in close proximity of the targeted nerve, for stabile neuromodulation applications.
