Publication number: 20220287759Abstract: 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.Type: ApplicationFiled: June 3, 2022Publication date: September 15, 2022Inventors: Jean Woloszko, Jonathan Gaspredes, David Yuan, Thomas P.

Publication number: 20210369326Abstract: An electrosurgical wand is disclosed for treating a plurality of tissues at a variety of tissue locations. The electrosurgical wand includes a handle on a proximal end and an elongate shaft with a combination active electrode at the distal end. The combination active electrode includes with a blade and screen portion; the blade portion extending along and laterally from the wand longitudinal axis, forming a dissecting tip. The screen portion extends from the blade portion at an obtuse angle and has at least one aspiration aperture through it. The wand also includes a second and third electrode, proximally spaced from the combination active electrode. The second electrode spans a portion of an outside surface of the wand adjacent the blade portion, while the third electrode spans a portion of the outside surface of the wand opposite the second electrode.Type: ApplicationFiled: August 4, 2021Publication date: December 2, 2021Inventors: Jean Woloszko, Jonathan Gaspredes, Douglas G. Evans, Robert Lathrop, Brendan Smith, David Turner, Christopher J. Aholt, Troy S. Hemme

Publication number: 20210169565Abstract: An electrosurgical wand is disclosed for providing a range of tissue treatment modes and for use in a variety of orientations. The electrosurgical wand includes a handle on a proximal end, an elongate shaft and at least three distinct electrodes disposed at a distal end of the wand. The three electrodes include a blade electrode having a length measured parallel to a longitudinal axis of wand, the length running parallel to the wand longitudinal axis for a portion of the length. The blade electrode has a distal portion that curves toward the longitudinal axis at the distal end of the wand. The three electrodes also include a second electrode disposed on a second side of the wand from the blade electrode; and a third electrode disposed between the blade electrode and the second electrode. All the electrodes have a different shape and surface area.Type: ApplicationFiled: May 16, 2018Publication date: June 10, 2021Applicant: Smith & Nephew, Inc.Inventors: Jean Woloszko, Jonathan Gaspredes, Douglas G.

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.Type: GrantFiled: June 26, 2017Date of Patent: October 22, 2019Assignee: ArthroCare CorporationInventors: Jean Woloszko, Jonathan Gaspredes, David Yuan, Thomas P.
