摘要: A method of treating an intervertebral disc includes inserting an introducer into an intervertebral disc, inserting a catheter through the introducer and into the intervertebral disc, advancing a distal region of the catheter through a nucleus pulposus of the intervertebral disc to an annular wall of an annulus fibrosus, delivering energy to material of the intervertebral disc using an electrode disposed at the distal region of the catheter, and removing the material with the delivered energy, wherein removing material with the delivered energy reduces pressure in the intervertebral disc.

摘要: A steerable electrophysiology catheter includes a shaft having a distal ablation segment with one or more electrodes coupled to a source of electrical energy by a connector extending through the shaft. The distal ablation segment of the shaft is movable between a collapsed configuration sized for percutaneous introduction into the patient and/or endoluminal delivery to the target site and an expanded configuration, in which the distal ablation segment forms a substantially continuous surface transverse to the shaft axis for engaging the heart tissue and creating a linear lesion thereon. The catheter includes one or more force element(s) positioned to apply an axial force between the distal and proximal ends of the ablation segment. The force element(s) provide a sufficiently uniform force against the distal ablation segment to establish continuous contact pressure between the electrodes and the patient's heart tissue. This contact pressure allows the surgeon to engage the entire length of the distal ablation segment against the heart tissue to provide a relatively long linear lesion on this tissue.
