ABSTRACT:
An incontinence electrode for controlling urinary incontinence in women is made of alternating regions of conductive and non-conductive polymers molded to form a flexible tubular body. Electrical leads couple the conductive regions to an electrical stimulation controller. The controller provides electrical current to the conductive regions at two different frequencies to cause a contraction of the vaginal muscles responsible for controlling urinary incontinence in women. The conductive regions have a volume resistivity which closely approximates the impedance of vaginal tissue, thereby substantially eliminating current density burns to the vaginal tissue.
