Abstract
An intervertebral disc device is provided comprising a distal probe sized to be extended from a distal end of an introducer that is percutaneously delivered into an interior of an intervertebral disc, a distal section of the probe comprising an active and return electrode which are each spirally wrapped around the probe such that there are multiple alternating bands of the same active and return positioned longitudinally along the length of the distal section of the probe, the active and return being adapted to deliver bipolar electromagnetic energy to tissue within the intervertebral disc; and a proximal handle for externally guiding the probe within an intervertebral disc.
