    a lower portion including at least one aperture extending there through;

    a first cable conductor mechanically and electrically coupled within the second lumen of the first terminal ring electrode;

    a second terminal ring electrode disposed over the inner tubular member such that it is radially offset from the first terminal ring electrode; and
