    摘要： Electrosurgical methods, systems, and apparatus for the controlled ablation of tissue from a target site of a patient. An electrosurgical apparatus of the invention includes an active electrode assembly having an active electrode screen surrounded by a plurality of flow protectors. Each flow protector defines a shielded region of the active electrode screen, each shielded region of the screen characterized by enhanced plasma formation. The active electrode assembly is adapted for removing tissue from a surgical site, and the active electrode screen is adapted for digesting fragments of resected tissue. In one embodiment, the apparatus is particularly suited to simultaneously removing both hard and soft tissue in, or around, a joint.

    摘要： Apparatus and methods for ablating, severing, cutting, shrinking, coagulating, or otherwise modifying a target tissue to be treated. In a method for treating a target tissue, an active electrode of an electrosurgical probe is positioned in at least close proximity to the target tissue in the presence of an electrically conductive fluid. A high frequency voltage is then applied between the active electrode and a return electrode, wherein, the high frequency voltage is sufficient to volumetrically remove (ablate), sever, or modify at least a portion of the target tissue. The probe comprises a multi-lumen shaft having a plurality of internal lumens, and a return electrode coil oriented substantially parallel to the shaft distal end. The active electrode may be in the form of a metal disc, a hook, or an active electrode coil. In the latter embodiment, the active electrode coil is typically arranged substantially orthogonal to the return electrode coil. Methods of making an active electrode coil, a return electrode coil, and an electrosurgical probe are also disclosed.

    摘要： Electrosurgical systems, apparatus, and methods for the controlled removal and treatment of a target tissue. An instrument of the invention includes a rotating member housed longitudinally within a shaft, a tissue removal port disposed at the shaft distal end portion, and an active electrode disposed at the instrument distal end. The active electrode is adapted to electrosurgically remove at least a portion of the target tissue as the rotating member rotates within the shaft. According to alternative embodiments, the active electrode may be disposed on the rotating member or on the shaft.

    摘要： Systems and methods for securing a screen-type active electrode to the distal tip of an electrosurgical device used for selectively applying electrical energy to a target location within or on a patient's body. A securing electrode is disposed through the screen electrode and mechanically joined to an insulative support body while also creating an electrical connection and mechanical enagement with the screen electrode. The electrosurgical device and related methods are provided for resecting, cutting, partially ablating, aspirating or otherwise removing tissue from a target site, and ablating the tissue in situ. The present methods and systems are particularly useful for removing tissue within joints, e.g., synovial tissue, meniscus, articular cartilage and the like.
