Abstract
A vaginal electrode adapted to be inserted into a woman's vagina and used as part of a stimulation system to stimulate and constrict muscles surrounding the vagina to prevent the flow of urine through the urethra. The electrode includes a nonconductive sheet of material formed into a diametrically compressible spiral tending to unwind. An exterior surface of the sheet contacts the interior vaginal wall after the electrode is inserted into a vagina. Conductive electrode elements circumferentially oriented on the exterior surface of the sheet are thereby forced into electrical contact with the vaginal wall. Leads couple electrical stimulation signals to the electrode elements.
