Abstract

An incontinence electrode for controlling urinary incontinence in women is made of alternating bands of conductive and non-conductive polymers molded to form a tubular body. Electrical receptacles, formed in the molding process at the interior circumferential surface of the conductive polymer bands, accept metal contacts attached to electrical leads to make a secure and durable, mechanical and electrical connection between the conductive polymer bands and the leads. The leads are coupled to a controller and carry electrical current to and from the metal contacts which then distribute the current to the conductive polymer bands to cause a contraction of the vaginal muscles responsible for controlling urinary incontinence in women.

Claims

1. A vaginal electrode, comprising:

a molded elongated tubular body, with an interior surface and an exterior surface and a longitudinal axis, having a plurality of conductive polymer bands separated by at least one non-conductive polymer band;

each conductive polymer band having a width and an electrical receptacle at the interior surface wherein the electrical receptacle includes a domed region with a cylindrical cavity having an inner diameter; and

a plurality of leads configured for connection to an electrical power source, each lead having a terminal end with an electrical contact mated to one of the electrical receptacles to make mechanical and electrical connection between the conductive polymer band and the lead.

2. The vaginal electrode of claim 1 wherein the electrical contact is a metal pin having an outer diameter larger than the inner diameter of the cylindrical cavity.

3. The vaginal electrode of claim 2 wherein the cylindrical cavity has a longitudinal axis generally parallel to the longitudinal axis of the tubular body.

4. The vaginal electrode of claim 1 wherein the conductive polymer bands have widths along the longitudinal axis of about 1/2 to about 3/4 inches.

5. The vaginal electrode of claim 4 wherein the conductive polymer bands have a separation of at least 1/16th to about 1/2 inch.

6. The vaginal electrode of claim 1 and further comprising a distal end cap located at a distal end of the elongated tubular body.

7. The vaginal electrode of claim 6 and further comprising a proximal end cap located at a proximal end of the elongated tubular body.

8. A vaginal electrode, comprising:

a molded elongated tubular body, with an interior surface and an exterior surface and a longitudinal axis, having a plurality of conductive polymer bands separated by at least one non-conductive polymer band, each conductive polymer band having a width and at the interior surface a domed region with a cylindrical cavity having an inner diameter along a longitudinal axis generally parallel to the longitudinal axis of the tubular body; and

a plurality of leads configured for connection to an electrical power source, each lead having a terminal end with an electrical contact mated to one of cylindrical cavities to make mechanical and electrical connection between the conductive polymer band and the lead.

9. The vaginal electrode of claim 8 wherein the electrical contact is a metal pin, having an outer diameter larger than the inner diameter of the cylindrical cavity.

10. The vaginal electrode of claim 8 wherein the conductive polymer bands have widths along the longitudinal axis of about 1/2 to about 3/4 inches.

11. The vaginal electrode of claim 10 wherein the conductive polymer bands have a separation of at least 1/16th to about 1/2 inch.

12. The vaginal electrode of claim 8 and further comprising a distal end cap located at a distal end of the elongated tubular body.

13. The vaginal electrode of claim 12 and further comprising a proximal end cap located at a proximal end of the elongated tubular body.
