    摘要： An implantable lead has a lead body construction designed to accommodate loading forces exerted on the lead body during patient movement. The lead body described herein is sufficiently stretchable to resist forces that could otherwise cause lead failure, axial migration of the electrodes, anchor damage, or tissue damage. The lead body may include a variety of features that reduce the axial stiffness of the lead without significantly impacting the operation and structural integrity of lead components, such as electrodes, conductors and insulators.

    摘要： An implantable lead has a lead body construction designed to accommodate loading forces exerted on the lead body during patient movement. The lead body may be sufficiently stretchable to resist forces that could otherwise cause lead failure, axial migration of the electrodes, anchor damage, or tissue damage. Increasing stretchability of a lead body can also increase the vulnerability of the lead body to flex fatigue, buckling fatigue, kinking, and crush. Therefore, the lead described herein includes a coiled wire embedded between a first insulative layer and a second insulative layer of an outer jacket of the lead body to improve column stiffness and kink resistance.

    摘要： An implantable lead has a lead body construction designed to accommodate loading forces exerted on the lead body during patient movement. The lead body may be sufficiently stretchable to resist forces that could otherwise cause lead failure, axial migration of the electrodes, anchor damage, or tissue damage. Increasing stretchability of a lead body can also increase the vulnerability of the lead body to flex fatigue, buckling fatigue, kinking, and crush. Therefore, the lead described herein includes conductors that comprise coiled wires positioned substantially parallel to a center axis of the lead. The conductors described herein may be coiled around fibers that limit the axial stiffness of the coiled wires to ensure full recovery from axial loading.

    摘要： A pulse stimulation system configured for implantation into a patient's body comprises a pulse stimulator, a conductive stimulation lead having a proximal end electrically coupled to the pulse simulator and having a distal end, and an electrode assembly coupled to the distal end of the stimulation lead. The electrode assembly comprises an electrode body having a therapy electrode thereon that is electrically coupled to the stimulation lead for delivering therapy to the patient. A floating electrode is configured to contact the patient's body tissue and has a surface area substantially larger than that of the therapy electrode. A filter is coupled between the therapy electrode and the floating electrode for diverting RF energy toward the floating electrode and away from the therapy electrode.
