Abstract:
1. A terminal connector assembly for a medical electrical lead comprising: an inner tubular member; a first terminal ring electrode disposed over the inner tubular member, the terminal ring electrode comprising: a first lumen having a generally D-shaped cross-section and defining a first longitudinal axis; an upper portion of the first terminal ring electrode including a second lumen extending along a second longitudinal axis parallel the first longitudinal axis and a blind hole having a lower surface formed in an outer surface of the upper portion such that the blind hole is disposed over the second lumen; and a lower portion of the first terminal ring electrode 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 the second terminal ring electrode is radially offset from the first terminal ring electrode; an insulator disposed over the inner tubular member and between the first and second terminal ring electrodes such that the first and second terminal ring electrodes are electrically isolated from one another; and wherein the D-shaped cross-section comprises a flat upper portion and a curved lower portion having a maximum depth of the D-shaped cross-section between the upper flat portion and the lower curved portion.
