Publication number: 20260096814Abstract: Tissue repair systems which use knotless all-suture anchors and have the ability to lock multiple repair sutures within the anchor construct. The anchor construct includes a tension suture wrapped or looped upon itself to create an open eyelet, through which multiple repair sutures originating in soft tissue are passed. The location of the eyelet may be anywhere inside the all-suture anchor or adjacent to the exterior of the anchor body. Tensioning of the tension suture causes the eyelet to restrict movement of the repair sutures and secures them within or against the anchor body.Type: ApplicationFiled: December 11, 2025Publication date: April 9, 2026Inventors: David Gregoire, Vincent Tangherlini, Ian Lo, Christopher Rodriguez, Tri Nguyen

Publication number: 20220249087Abstract: Suture pulling devices are disclosed which are adapted to lock onto a target tissue by use of a pair of jaws and pull a strand of suture through the target tissue so that without opening the closed jaws, the strand of suture has been pulled through the tissues but maintained within the volume defined by the pair of jaws.Type: ApplicationFiled: July 22, 2020Publication date: August 11, 2022Inventors: David R.

Patent number: 11202623Abstract: A suturing device for grasping soft tissue and placing stitches in soft tissue during endoscopic procedures is described. An elongate housing with a stationary jaw and a movable jaw disposed at the distal end are configured for grasping and releasing soft tissue. A movable needle disposed within the housing is actuated to engage a length of suture and drive the suture into and through the grasped soft tissue. A suture capture member is disposed on the movable jaw and is configured to allow passage of the needle therethrough while securing a portion of the stitched length of suture.Type: GrantFiled: July 2, 2019Date of Patent: December 21, 2021Assignee: ArthroCare CorporationInventors: David Gregoire, George W.

Patent number: 10675142Abstract: A tissue fixation device for securing soft tissue to bone includes an expandable outer sheath, and an inner screw in threaded cooperation with the sheath. The expandable sheath comprises opposing walls in hinged engagement. When the screw is inserted into in the sheath, the walls pivot outwardly about a distal hinge to compress a tissue graft against the bone hole, and to lock the device therein. An optional cortical button is secured across the bone hole entrance, and tethered to the fixation device to bolster fixation.Type: GrantFiled: April 7, 2016Date of Patent: June 9, 2020Assignee: MV N8TIVE, LLCInventors: David Gregoire, George White, Christopher Rodriguez, Mark Harrold

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: 9814565Abstract: A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. The suture locking wedge includes lateral portions which engage slots or windows in the anchor body. Tension applied to one limb of a suture causes the suture locking wedge to translate and rotate to a position which compresses the suture, thereby locking the suture in the anchor.Type: GrantFiled: April 17, 2015Date of Patent: November 14, 2017Assignee: ArthroCare CorporationInventors: Seth A Foerster, Steven Wolf, Emil Karapetian, George W.

Patent number: 9364210Abstract: A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. Tension applied to one side of a suture causes the suture locking wedge to translate and rotate into a position which compresses the suture, thereby locking the suture in the anchor. A resilient or spring biasing member within the anchor device urges the suture locking wedge to compress the suture, facilitating suture locking.Type: GrantFiled: January 27, 2012Date of Patent: June 14, 2016Assignee: ArthroCare CorporationInventors: David Gregoire, George W.
