摘要： A medical system for electrical stimulation includes a first column of electrodes, a second column of electrodes, an expandable member disposed between first and second columns, and an expansion mechanism adapted to transmit an externally applied pressure to the expandable member. The pressure expands the expandable member in order to force the first column of electrodes apart from the second column of electrodes. The first and second columns, disposed side-by-side, may be inserted through a percutaneous needle and into a epidural space, alongside a spinal cord; after insertion, the first column may be forced apart from the second column by applying the pressure to the expandable member.

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.
