    • Electrical medical leads having active fixation electrodes, particularly helix electrodes intended to be screwed into body tissue, e.g., the heart, are disclosed having selectively applied insulation to optimize exposed electrode surface area and dispose the exposed electrode surface area toward tissue that is less traumatized by injury caused by screwing in the fixation helix. In a preferred fabrication method, an outer helical surface is masked by contact with a masking tube while a dielectric coating is applied to the inner helical surface of the coil turns of the helix, and the masking tube is removed when the dielectric coating has set. In one variation, at least one aperture is formed through the masking tube sidewall exposing an area of the outer helical surface thereby interrupting the uninsulated outer helical electrode.
    • 公开了具有主动固定电极的电医疗引线,特别是旨在拧入人体组织(例如心脏)中的螺旋电极,其具有选择性施加的绝缘以优化暴露的电极表面区域并且将暴露的电极表面区域朝向组织 拧入固定螺旋引起的损伤。 在优选的制造方法中,通过与屏蔽管接触而屏蔽外螺旋表面,同时将介电涂层施加到螺旋的线圈匝的内螺旋表面上,并且当介电涂层凝固时去除掩蔽管。 在一个变型中,穿过掩蔽管侧壁形成至少一个孔,从而暴露外部螺旋形表面的区域,从而中断未绝缘的外部螺旋形电极。
