  • Patent number: 8979838
    Abstract: Electrosurgical system and related methods that include: producing energy by a generator of an electrosurgical controller, the generator comprises a first terminal coupled to a first electrode of an electrosurgical wand, and the generator comprises a second terminal coupled to a second electrode of the electrosurgical wand; forming, responsive to the energy, a plasma proximate to the first electrode, while the second electrode acts as a return electrode; reducing energy output of the generator such that the plasma proximate the first electrode is extinguished, then producing energy from the generator with the first terminal coupled to the first electrode and the second terminal coupled to the second electrode; and forming, responsive to the energy, a plasma proximate to the second electrode, while the first electrode acts as a return electrode.

  • Publication number: 20150032101
    Abstract: System and method for selectively applying electrical energy to structures within or on the surface of a patient's body and controlling the flow of an electrically conductive fluid from the application site to provide or maintain a desired operating condition of the electrosurgical device. An electrosurgical probe is in communication with a fluid transport apparatus through a fluid transport lumen having an opening at an end proximate the application site and disposed proximate the electrosurgical probe. A controller in communication with the fluid transport apparatus provides control signals to the fluid transport apparatus in response to at least one operating parameter associated with the system. Based on the received control signals, the fluid transport apparatus adjusts a flow rate of the electrically conductive fluid at the application site through the fluid transport lumen in response to at least one operating parameter associated with the system.

  • Publication number: 20140257279
    Abstract: Electrosurgical wands. At least some of the illustrative embodiments are electrosurgical wands having features that reduce contact of tissue with an active electrode of a wand, decrease the likelihood of clogging, and/or increase the visibility within surgical field. For example, wands in accordance with at least some embodiments may comprise standoffs, either along the outer perimeter of the active electrode, or through the main aperture in the active electrode, to reduce tissue contact. Wands in accordance with at least some embodiments may implement slots on the active electrodes to increase bubble aspiration to help keep the visual field at the surgical site clear. Wands in accordance with at least some embodiments may implement aspiration flow pathways within the wand that increase in cross-sectional area to reduce the likelihood of clogging.

  • Publication number: 20140257269
    Abstract: Electrosurgical methods and systems. At least some of the illustrative embodiments are methods including maintaining plasma proximate to an active electrode in a first energy range, and a second energy range. During periods when plasma is proximate to the active electrode, the illustrative method may include controlling flow of fluid drawn into an aperture of an electrosurgical wand, and in some situations increasing fluid flow drawing into the aperture responsive to the active electrode being in operational relationship with tissue, and in other cases decreasing fluid flow drawing into the aperture responsive to the active electrode being in operational relationship with tissue. Further, during periods when plasma is proximate to the active electrode, the illustrative method may include providing output energy at a default energy setpoint, and then providing output energy at a second energy setpoint.

  • Patent number: 8801705
    Abstract: 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 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. An apparatus includes a plurality of active electrodes and a distal section including two bends. The bends serve to prevent the active electrodes from impinging upon the shaft of an introducer needle. 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 site during an application.

  • Publication number: 20140207189
    Abstract: An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. The suturing material between the soft tissue and the bone anchor may be secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suture around a suture return member or path within the bone anchor, tightening the suture and attached soft tissue, and compressing the suture against the bone anchor. The bone anchor may be a tubular body having a lumen with a locking plug that compresses the suture therein. One of the components of the locking structure may include a deformable or flexible section, member, or surface. The locking plug may include a shaft and an enlarged head that interferes with the tubular body to provide a positive stop.

  • Publication number: 20140200581
    Abstract: The present disclosure includes an electrosurgical apparatus for treating tissue at a target site. The apparatus has a shaft with a proximal end and a distal portion, the distal portion comprising a return electrode and electrode support. There is also at least one active electrode on the shaft distal portion, which has a proximal portion and a distal portion and a plurality of aspiration apertures disposed therebetween. These apertures are fluidly connected to a fluid aspiration cavity that is located within the electrode support, and the cavity is connected with a fluid aspiration element that is located along the shaft. The plurality of apertures vary in size and are generally arranged so that the larger sized apertures are disposed towards the electrode proximal portion and the smaller sized apertures are generally located towards the electrode distal portion.

  • Patent number: 8663216
    Abstract: 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 electrosurgical probe or catheter is positioned adjacent the target site so that one or more active electrode(s) are brought into contact with, or close proximity to, a target tissue in the presence of electrically conductive fluid. High frequency voltage is then applied between the active electrode(s) and one or more return electrode(s) to non-thermally generate a plasma adjacent to the active electrode(s), and to volumetrically remove or ablate at least a portion of the target tissue.
