  • Electrical stimulation lead with stiffeners having varying stiffness zones
    Patent number: 8532788
    Abstract: In one embodiment, a neurostimulation lead comprises an elongated body of insulative material, comprising a first end portion and a second end portion; a plurality of terminals longitudinally positioned along the first end portion; a plurality of electrodes longitudinally positioned along the second end portion; a plurality of conductors electrically coupling the plurality of electrodes to the plurality of terminals; a flexible metal longitudinal stiffener positioned within the elongated body wherein the stiffener has a plurality of longitudinal zones and each zone has a different column strength, the column strength of one or more zones of the plurality of longitudinal zones being defined by cuts or gaps in the stiffener, the stiffener causing the neurostimulation lead to exhibit a greatest amount of column strength adjacent to one end portion of the elongated body and to transition to a lower column strength toward a medial portion of the elongated body.
    Type: Grant
