Abstract
Various embodiments concern a lead having a proximal section and a curbed section. The lead can comprise an outer tubular portion having a bias such that the lead assumes a curved shape along the curved section. The lead can further include an inner tubular portion extending within the outer tubular portion, the inner tubular portion comprising an inner coil conductor and an inner polymer jacket over the inner coil conductor along the curved section, the inner tubular member stiffer along the proximal section than the curved section, the outer tubular portion stiffer along the curved section relative to the inner tubular portion along the curved section such that the inner tubular portion can rotate relative to the outer tubular portion while the curved shape is substantially maintained. Relative rotation can extend and rotate and active fixation element.
