Mri compatible implanted lead-electrode interface

An electrical lead that is adapted for implantation in an animal, said electrical lead comprising:

• a cable having a helical electrical conductor enclosed within a sheath of electrically insulating material;
• a stimulation electrode for applying electric current to tissue of an animal, the stimulation electrode has first contact band with first and second sides and a threaded lumen extending between the first and second sides, a second contact band that has third and fourth sides and a threaded aperture extending between the third and fourth sides, and a helical electrode coil that is screwed into the threaded lumen from the second side of the first contact band and is screwed into the threaded aperture from the third side of the second contact band, wherein the first and second contact bands are separated from each other thereby exposing a section of the helical electrode coil to an exterior of the electrical lead, and wherein a portion of the helical electrical conductor of the cable is screwed into the threaded lumen from the first side of the first contact band.
