  • Implantable medical electrical lead bodies providing improved electrode contact
    Patent number: 8041434
    Abstract: A distal section of an implantable medical electrical lead body includes a pair of pre-formed arcuate segments between which an approximately straight segment extends. The approximately straight segment includes a first portion extending distally from a first of the pair pre-formed arcuate segments, a second portion extending from the first portion, a third portion extending from the second to a second of the pair pre-formed arcuate segments. An electrode is coupled to the second portion of the approximately straight segment, and the adjacent first portion has a stiffness which is less than that of the first of the pair pre-formed arcuate segments and preferably less than the stiffness of the third portion, so that, when the distal section of the lead body is implanted, for example, within a cardiac vein, the lead buckles to bring the electrode into closer contact with surrounding tissue.
    Type: Grant
