Publication number: 20170333026Abstract: A suture anchor assembly includes an anchor body having a central longitudinal axis, a proximal end, a distal end, a passage extending along the central longitudinal axis from an opening at the proximal end through a portion of a length of the anchor body, and a helical thread that defines a perimeter the proximal end of the anchor body. The passage has a first wall portion and a second wall portion. A rigid support extends across the passage and has a first portion and a second portion spaced from the first portion. The first portion is attached to the first wall portion and the second portion is attached to the second wall portion. A suture strand having a suture length is threaded into the passage, supported by the rigid support, and threaded past the proximal end of the anchor body. The rigid support is spaced axially away from the opening, and the suture strand extends out of the opening of the anchor body.Type: ApplicationFiled: April 14, 2017Publication date: November 23, 2017Inventors: Peter J.

Patent number: 9801621Abstract: Techniques and reconstruction systems for soft tissue surgical repairs. The biceps tenodesis technique of the present invention provides fixation of a single diameter of the biceps tendon in a socket without the need for externalizing the tendon and without the need to pass any suture (or similar material) through any portion of the tendon (i.e., without the need to stitch or whipstitch any area/portion of the tendon). The technique improves the biomechanics of the combined fixation and helps overcome surgeons' concerns about rapid return to ADLs.Type: GrantFiled: January 23, 2015Date of Patent: October 31, 2017Assignee: Arthrex, Inc.Inventor: William C. Benavitz

Publication number: 20170209135Abstract: Surgical devices and methods of surgical repairs using the devices are disclosed. The device and methods aid in surgical repairs by allowing for quick and reproducible repairs to be made. A tensionable knotless fixation device is provided with a tensioning construct (formed of a tensioning strand, a tensionable, adjustable, knotless, self-cinching loop, and a splice adjacent the loop) pre-loaded onto a fixation device. A flexible material (for example, suture or suture tape) may be attached to a fixation device.

Publication number: 20170119366Abstract: Surgical methods for stabilizing a joint are disclosed. The methods aid in surgical repairs by allowing for quick and reproducible repairs to be made. A bone tunnel is formed anteriorly/posteriorly in clavicle, and a bone tunnel is formed superiorly in acromion. At least one cannulated insert is provided into one or both of bone tunnels to protect the bone from abrasions caused by a flexible construct. A flexible construct is passed through the acromion tunnel and the clavicle tunnel. An attachment device may then be positioned on at least one side of the clavicle and/or acromion tunnel, and the flexible construct is attached to the attachment device.Type: ApplicationFiled: October 28, 2015Publication date: May 4, 2017Inventors: William C.

Publication number: 20150351780Abstract: Instrumentation for elbow reconstruction, specifically, for repairs of the ulnar collateral ligament (UCL). The instrumentation provides for precise formation of sockets and tunnels along with easy suture/graft passage while accommodating all forms of elbow UCL reconstruction techniques. A V-drill guide is provided with a handle and two drill sleeves having intersecting trajectories for creating an intersecting V-shaped bone tunnel in the ulna. An adjustable humeral guide has an adjustable arm with an arc shape, and a peg and a block extending from each end of the adjustable arm. The peg is shaped to fit within an already-formed humeral socket. The block allows a drill to pass through and form other tunnels which intersect with the originally-formed tunnel at various positions.Type: ApplicationFiled: August 19, 2015Publication date: December 10, 2015Inventors: Kyle Anderson, Neal EIAttrache, William C. Benavitz, John Conway, Anthony A. Romeo, Derek C. Sullivan, Jonathan Webb

Patent number: 8801755Abstract: A suture anchor assembly includes an anchor having a proximal end, a distal end, a longitudinal axis, a first length, and an internal passage within the anchor. The internal passage begins at an opening in the proximal end and has a second length shorter than the first length. A support structure fixed longitudinally relative to the anchor extends across the internal passage and has a third length shorter than the second length. A suture within the internal passage is received about a distal surface of the support structure. A suture extends out of the opening in the proximal end. A driver includes a cannula having a distal opening and a proximal opening, and the suture is received within the cannula. A first end and the second end of the suture extend outside of the proximal opening, the driver having a drive surface near the distal opening that engages the anchor.Type: GrantFiled: January 6, 2014Date of Patent: August 12, 2014Assignee: Arthrex, Inc.Inventors: Peter J.

Patent number: 8764797Abstract: An insert-molded suture anchor with a biodegradable polymer body in which a loop of suture is totally contained within the polymer. The suture anchor body features a drive end that is shaped to be received into a recess in the end of a hand driver. Anchoring ribs are formed along the remaining length of the anchor. The loop of suture which includes and eyelet for attaching a suture strand is totally embedded within the anchor body during the insert-molding fabrication process. The anchor is produced by placing the suture in an injection mold, and injecting biodegradable polymer into the mold.Type: GrantFiled: December 12, 2006Date of Patent: July 1, 2014Assignee: Arthrex, Inc.Inventors: Peter J.
