The present invention provides improvements to an implant, system and method using passive electrical conductors which route electrical current to either external or implanted electrical devices, to multiple target body tissues and to selective target body tissues. The passive electrical conductor extends from subcutaneous tissue located below either a surface cathodic electrode or a surface anodic electrode a) to a target tissue to route electrical signals from the target body tissue to devices external to the body; b) to implanted electrical devices to deliver electrical current to such devices, or c) to multiple target body tissues or to selective target body tissues to stimulate the target body tissues. The conductor has specialized ends for achieving such purposes.

1. An apparatus, comprising: a passive electrical conductor having a first end portion and a second end portion, the first end portion including a stimulation electrode, the second end portion including a pick-up electrode, the passive electrical conductor configured to be disposed within a body such that the stimulation electrode is disposed adjacent a target tissue and the pick-up electrode is entirely beneath a surface of a skin; andan insulation member coupled to the second end portion of the passive electrical conductor, the insulation member configured to define, at least in part, a current pathway within the body along which a portion of an electrical current flows between a surface electrode coupled to the surface of the skin and the pick-up electrode. 2. The apparatus of claim 1, wherein the passive electrical conductor is insulated between the first end portion and the second end portion. 3. The apparatus of claim 1, wherein the insulation member is constructed from any one of silicone and polyester. 4. The apparatus of claim 1, wherein the insulation member is configured to inhibit the flow of the electrical current through a portion of a subcutaneous tissue. 5. The apparatus of claim 1, wherein at least a portion of the insulation member is disposed between the pick-up electrode and the stimulation electrode. 6. The apparatus of claim 1, wherein at least a portion of the insulation member is disposed about a periphery of the pick-up electrode. 7. The apparatus of claim 1, wherein: the pick-up electrode is a first pick-up electrode from a plurality of pick-up electrodes; andthe insulation member is configured to be movably coupled to the passive electrical conductor such that the insulation member can selectively cover a second pick-up electrode from the plurality of pick-up electrodes. 8. The apparatus of claim 1, wherein at least a portion of the pick-up electrode has a coil shape. 9. The apparatus of claim 1, wherein the stimulation electrode is a stimulation electrode from a plurality of stimulation electrodes. 10. The apparatus of claim 1, wherein a surface area of the stimulation electrode is less than approximately 50 square millimeters. 11. The apparatus of claim 1, wherein a surface area of the stimulation electrode is between approximately 10 square millimeters and approximately 50 square millimeters. 12. The apparatus of claim 1, wherein: the pick-up electrode is a pick-up electrode from a plurality of pick-up electrodes; andthe stimulation electrode is a stimulation electrode from a plurality of stimulation electrodes, each stimulation electrode from the plurality of stimulation electrodes being electronically coupled to a corresponding pick-up electrode from the plurality of pick-up electrodes. 13. The apparatus of claim 1, further comprising: an anchor coupled to the first end portion of the passive electrical conductor, the anchor configured to limit movement of the stimulation electrode relative to the target tissue when the passive electrical conductor is disposed within the body. 14. A method, comprising: inserting a conductive member within a body such that a stimulating electrode disposed at a distal end portion of the conductive member is adjacent a target tissue within the body and a pick-up electrode disposed at a proximal end portion of the conductive member is beneath a surface of a skin of the body; andmoving at least a portion of an insulation member relative to the proximal end portion of the conductive member after the inserting. 15. The method of claim 14, wherein an exterior surface of the conductive member is insulated between the distal end portion and the proximal end portion. 16. The method of claim 14, wherein the moving includes sliding the portion of the insulation member about the pick-up electrode. 17. The method of claim 14, wherein the moving includes defining at least a portion of a current pathway within the body between the surface of the skin and the pick-up electrode. 18. The method of claim 14, wherein the moving includes positioning at least the portion of the insulation member between the pick-up electrode the stimulation electrode. 19. The method of claim 14, further comprising: coupling a surface electrode to the surface of the skin such that at least a portion of the pick-up electrode is below the surface electrode. 20. The method of claim 14, wherein the insulation member is coupled to the proximal end portion of the conductive member before the inserting.
