摘要： A method for treating a bone body comprises inserting a probe having at least one active electrode into the target tissue and applying a voltage difference between an active electrode and a return electrode to ablate the tissue. The method is particularly directed to removing tumors in a bone body and or removing cancellous bone in a bone body. The bone body may be a vertebral body. The devices include electrosurgical probes which enable their electrodes to access tissue at trajectories beyond that of the access channel through which they are delivered to the target tissue. Also, a kit includes an electrosurgical probe, an electrosurgical generator, an introducer needle, and a fluid connector to connect the introducer needle to a fluid source such that liquid may be supplied to the target tissue during an application.

摘要： A bone anchor adapted to secure soft tissue to bone. The anchor includes a first body section and a second body section proximal to the first body section. The first section has a non-circular cross section such that once the implant is inserted into a shaped bone tunnel it may be secured in the tunnel by rotation from its initial insertion position to a second position. The dissimilarity of the non-circular cross section of the proximal end of the first section prevents removal of the bone anchor from the bone tunnel. Additionally, a suture may be threaded through a hole in the second section. Once the anchor is secured in place with an attached suture, the free ends of the suture, the free ends of the suture may be threaded through soft tissue and tied down to secure the soft tissue to bone.

The method is particularly directed to removing tumors in a bone body and or removing cancellous bone in a bone body. The bone body may be a vertebral body. An apparatus includes a plurality of active electrodes and a distal section including two bends.

摘要： Instruments and methodology for nonlinear access to bone tissue sites are described. Embodiments disclosed include a conduit (70) for delivering material or a medical device to a site and a core member (82) that is able to steer the conduit (80) and allow the combination to be advanced thorough cancellous bone. A cannula (48) and stylet (52) may be provided to first advance through hard bone. The core member (82) includes a curved tip (96) that may be straightened by the cannula (40) or an actuator sheath (92) to vary sweep of the curve. An obturator (140) may be included in the system. This instrument may include a flexible portion (150) as well. Each of the obturator (140) and conduit (70) may be provided with any of a variety of active tips (160). The systems may be used to perform hard tissue site implantation, for example, in connection with a high pressure injection system.

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 (2720) having an active electrode screen (2708) surrounded by a plurality of flow protectors (2752 a-d). 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： The present invention provides systems, apparatus, and methods for dissecting, resecting, severing, cutting, contracting, coagulating, or otherwise modifying a tissue or organ of a patient. An apparatus of the invention includes an electrosurgical probe (1400) configurable between an open configuration and a closed configuration, the probe including an active electrode terminal, a fixed return electrode disposed proximal to the active electrode terminal, and a movable return electrode configured to move linearly with respect to the active electrode terminal between the open configuration and the closed configuration. A method of the present invention comprises clamping a blood vessel between the active electrode terminal and the movable return electrode, coagulating the clamped blood vessel by application of a first high frequency voltage, and severing the coagulated blood vessel by application of a second high frequency voltage.

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 (20) 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 (203) and a return electrode (112), wherein, the high frequency voltage is sufficient to volumetrically remove (ablate), sever, or modify at least a portion of the target tissue. The probe (20) 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 (203) may be in the form of a metal disc, a hook, or an active electrode coil. In the latter embodiment, the active electrode coil (203) 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： Systems and methods are provided for applying a high frequency voltage in the presence of an electrically conductive fluid to create a relatively low temperature plasma for ablation of tissue adjacent to, or in contact with, the plasma. In one embodiment, an electro-surgical probe (20) or catheter is positioned adjacent the target site so that one or more active electrode(s) (120) are brought into contact with, or close proximity to, a target tissue in the presence of electrical conductive fluid. High frequency voltage is then applied between the electrode terminal(s) (120), and one or more return electrode(s) (112) to generate a plasma adjacent to the active electrode(s), and to volumetrically remove or ablate at least a portion of the target tissue. The high frequency voltage penetrates electric fields around the active electrode(s) with sufficient energy to ionize the conductive fluid adjacent to the active electrode(s). Within the ionized gas or plasma, free electrons are accelerated, and electron atoms collisions liberate more electrons. The process cascades until the plasma contains sufficient energy to break apart the tissue molecules, causing molecular dissociation, and ablation of the target tissue.
