Publication number: 20170258519Abstract: An electrosurgical probe can be detachably secured to a handpiece having a motor drive unit and an RF current contact. The electrosurgical probe includes an elongate shaft having a longitudinal axis, a distal dielectric tip, and a proximal hub which is detachably securable to the handpiece. A hook electrode is reciprocatably mounted in the distal dielectric tip, and an RF connector on the hub is couplable to the RF current contact in the handpiece when the hub is secured to the handpiece. A drive mechanism in the hub mechanically couples to the hook electrode, and drive mechanism engages a rotational component in the motor drive unit when the hub is secured to the handpiece. The drive mechanism converts rotational motion from the rotational component into axial reciprocation and transmits the axial reciprocation to the hook electrode to axially displace the hook electrode between a non-extended position and an extended position relative to the dielectric tip.Type: ApplicationFiled: March 9, 2017Publication date: September 14, 2017Applicant: RELIGN CorporationInventors: Aaron Germain, Kyle Klein, Steffan Benamou, Jeffrey Norton, Jacob Tonkel

Publication number: 20170258512Abstract: An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.Type: ApplicationFiled: March 9, 2017Publication date: September 14, 2017Applicant: RELIGN CorporationInventors: Aaron Germain, Simon Malkevich, Steffan Benamou, Kyle Klein, Ben Poser

Publication number: 20170252099Abstract: An elongated shaft assembly includes a rotatable inner cutting sleeve and a non-rotating outer sleeve. A window of the inner cutting sleeve is selectively rotatable within an opening of the non-rotating outer sleeve to cut tissue with a sharpened cutting blade when rotated in a first rotational direction and to cut tissue with an electrode when rotated in a second rotational direction.Type: ApplicationFiled: May 18, 2017Publication date: September 7, 2017Applicant: RELIGN CorporationInventors: Benedek Orczy-Timko, Aaron Germain

Publication number: 20170224368Abstract: A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having sharp edges formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high speed to cut bone and other hard tissue. An electrode is carried in a surface portion of ceramic cutting member for cautery or radiofrequency ablation of tissue when the sleeve and cutting member are is a stationary position.Type: ApplicationFiled: January 31, 2017Publication date: August 10, 2017Applicant: RELIGN CorporationInventors: Aaron Germain, Kyle Klein, Michael D. Walker, Salvatore G. Mangano

Publication number: 20170202612Abstract: An electrosurgical probe for ablating tissue includes an elongated shaft having an axis and a distal end. An electrically insulating housing at the distal end of the shaft has a window, and an interior channel in the shaft extends through the housing to the window. The window faces laterally relative to the axis, and a moveable member with a blade-like electrode edge is disposed within the window. A motor drives the energized electrode edge axially in the window to ablate tissue.Type: ApplicationFiled: January 19, 2017Publication date: July 20, 2017Applicant: RELIGN CorporationInventors: Aaron Germain, Jeff Norton, Jan Echeverry, Evan Nessim, Sal Mangano

Publication number: 20170172648Abstract: A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.Type: ApplicationFiled: March 3, 2017Publication date: June 22, 2017Applicant: RELIGN CorporationInventors: Aaron Germain, Kyle Klein, Michael D. Walker, Ben Poser
