    摘要: Apparatus and methods are disclosed for accessing the interior of an intervertebral disc to perform a function within the disc. One such apparatus comprises a catheter having a lumen; and a guide wire having a distal portion and a proximal portion, and configured to be positioned within and moved relative to the lumen of the catheter; wherein the guide wire is capable of navigating itself within an intradiscal section of the intervertebral disc to a selected section of the disc and the catheter is capable of being advanced relative to the guide wire such that the catheter follows a path of the guide wire within the intradiscal section of the disc to the selected section. These apparatus and methods may be used for the treatment of intervertebral disc disorders such as sealing fissures of the annulus fibrosus, which may or may not be accompanied with contained or escaped extrusions. These apparatus and methods may also be used, for example, for the removal or addition of material to the intervertebral disc.

    摘要: A high frequency treatment instrument for an endoscope is provided. The high frequency treatment instrument is provided with an insulative flexible sheath, an operation wire inserted in the flexible sheath so as to be movable along an axial direction of the operation wire in the flexible sheath, and a hook-like electrode attached to a tip of the operation wire. The hook-like electrode includes a rod-like part which is elongated in parallel with the axial direction along a line shifted from an axis line of the operation wire, and a hook part elongated from the rod-like part to cross the axis line of the operation wire.
