Incontinence electrode apparatus
First Claim
1. An electrical stimulation system for controlling urinary incontinence comprising:
- an elongated tubular body having an interior surface and an exterior surface, the tubular body further having first, second and third conductive regions, each conductive region having a volume resistivity in the range of approximately 1 to 2500 ohm-centimeters and separated by at least one non-conductive region, the first, second and third conductive regions configured to provide a first current path and a second current path, wherein the first and second current paths share one of the conductive regions; and
electrical stimulation means communicating with the first, second and third conductive regions, for delivering a first signal at a first frequent to the first current path, and for delivering a second signal at a second frequency, different from the first frequency, to the second current path.

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.
