    摘要: An electrosurgical aspiration instrument that permits aspiration of an area being treated by the instrument. The instrument is coupled at a proximal end to a power source and includes an energy application surface area at a distal end. The power source supplied energy to the energy application surface area such that the distal end of the instrument may apply energy to the treatment area to modify the characteristics of biological material, such as biological tissue in the area. An aspiration lumen is formed through the instrument with an opening through the energy application surface area. The energy application surface area is configured to reduce blockage of the opening. Accordingly, aspiration may be performed simultaneously with electrosurgical treatment whereby unwanted matter such as by-products, biological debris and excess fluid is removed from the treatment area. The electrosurgical aspiration instrument also permits both functions to be performed at different times, with the advantage of not requiring instruments to be switched on during the treatment procedure or removed from the treatment site.

    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.
