  • Patent number: 10828081
    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.

  • Patent number: 10463364
    Abstract: In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.

  • Patent number: 10448988
    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.
