Title
(EN) Method of routing electrical current to bodily tissues via implanted passive conductors
Abstract
(EN)
The invention provides an implant for electrically stimulating a target body tissue in a subject. The implant provides a conductive pathway for a portion of electrical current flowing between surface electrodes positioned on the subject's skin and transmits that current to the target body tissue. The implant has an electrical conductor of sufficient length to extend from subcutaneous tissue located below a surface cathodic electrode to the target body tissue. The conductor has a pick-up end which forms an electrical termination having a sufficient surface area to allow a sufficient portion of the electrical current to flow through the conductor, in preference to flowing through body tissue between the surface electrodes, such that the target body tissue is stimulated. The conductor also has a stimulating end which forms an electrical termination for delivering the current to the target body tissue. A system and method incorporating the implant are also provided.
