Patent number: 10463364Abstract: 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.Type: GrantFiled: May 2, 2017Date of Patent: November 5, 2019Assignee: ArthroCare CorporationInventors: George W. White, David Gregoire, David Aldridge, Edward E. Dolendo, Emil Karapetian, Norman S. Gordon, Tri Nguyen

Patent number: 10448988Abstract: 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: GrantFiled: June 26, 2017Date of Patent: October 22, 2019Assignee: ArthroCare CorporationInventors: Jean Woloszko, Jonathan Gaspredes, David Yuan, Thomas P.

Patent number: 10265062Abstract: A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.Type: GrantFiled: February 28, 2014Date of Patent: April 23, 2019Assignee: ArthroCare CorporationInventors: Seth A.

Publication number: 20180228484Abstract: A knotless tissue repair assembly for attachment of tissue to bone includes an anchoring implant with a length of suture threaded therethrough. The implant is preferably a soft flexible three-dimensional structure. The implant may be actuated from a first elongate low profile shape into a second short radially expanded shape having a larger diameter than the hole through which it was placed. The suture extends through the anchor, through a tissue to be secured, and back through a designated suture-binding region or passageway within the anchor enabling the suture to be secured therein and without the need for a physician to tie a knot. Further tension applied to a suture leg approximates the tissue to the anchor until a desired tension or distance between the tissue and anchor is achieved.Type: ApplicationFiled: April 11, 2018Publication date: August 16, 2018Applicant: ArthroCare CorporationInventors: Christopher Rodriguez, Tri Nguyen

Patent number: 9962149Abstract: A tissue repair assembly for attachment of tissue to bone or tissue to tissue having a soft anchoring implant 100 with a length of suture 120 there through for tensioning the implant and facilitating attachment of other tissue. The implant 100 is a soft, flexible, three-dimensional structure that has a resident volume 200. An inserter tube 310 facilitates the placement of the implant 100 into bone or adjacent soft tissue where it may be deployed. Upon deployment, the soft anchoring implant 100 shortens axially and expands radially, achieving a larger diameter than the hole through which it was placed, thus resisting pull out.Type: GrantFiled: November 14, 2012Date of Patent: May 8, 2018Assignee: ArthroCare CorporationInventors: Treg Brown, Nathaniel Cohen, Robert Fernandez, Richard D'Elia, Christopher D'Elia, Annette Branger, Steve Golden, Marnette Atkinson, Stewart Kume
