A wound closure assembly includes an insertion tool having a proximal end and a distal section, such as a curved distal section, having a penetrating tip and first and second notches that are formed on opposite sides of the distal section. The assembly includes a tissue anchor having a hollow body and an insertion tool channel extending through the hollow body. First and second spaced tips project distally from the distal end of the hollow body and oppose one another on opposite sides of the insertion tool channel. The distal section of the insertion tool is inserted into the insertion tool channel of the tissue anchor so that the penetrating tip is distal to the first and second spaced tips, with the first and second spaced tips nested within the first and second notches for generating a releasable interference fit between the tissue anchor and the insertion tool.

Surgical constructs, assemblies and methods of tissue fixation are disclosed. An anterior glenoid guide is a cuboid block configured to be introduced via the rotator interval to lie on the anterior glenoid. The guide has an internal thread for a handle and two flanges which lie on the anterior glenoid. On the anterior face (opposite the neck of the glenoid), the guide is provided with two holes which are sized to receive a drill guide. The holes mate with slots such that the block can be removed after sutures and fixation devices are installed. The anterior glenoid guide can be an arthroscopic anterior glenoid graft guide.

Systems, devices, and methods are provided for attaching and supporting a bone suture. In particular, described herein are embodiments of implantable bracing apparatuses comprising one or more curved tubes configured to be implanted in one or more bone tunnels, and further configured to pass one or more sutures therethrough. Embodiments of methods of creating a bracing apparatus in situ by injecting a fluidic agent into a bone tunnel and inducing a phase transition are also described. Furthermore, described herein are embodiments of tunneling devices for creating a bone tunnel, which can be used with any of the bracing apparatuses described herein.

Bone anchors having improved fixation are discussed. The bone anchors include an anchor body and radially protruding ribs that extend approximately parallel to a longitudinal axis of the bone anchor. A leading distal edge of each rib may be configured in a tapered “knife-edge” configuration. Such ribs may mitigate the plow-out effect, preserving contact between the ribs and the surrounding bone along the length of the anchor. Furthermore, such ribs provide increased surface area, improving fixation strength.

An insertion device includes an elongate member and a stylet. The elongate member has a proximal end portion, a distal end portion, and defines a lumen therethrough. The stylet has a proximal end portion, a distal end portion, and is slidably coupled to the elongate member. The stylet is configured to move from a first position to a second position with respect to the elongate member. The proximal end portion of the stylet is configured to removably couple a mesh carrier thereto. A portion of the proximal end portion of the stylet is disposed outside of the lumen of the elongate member when the stylet is in its first position and is disposed within the lumen when the stylet is in its second position.

Apparatus for securing a first object to a second object, the apparatus comprising: an elongated body having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end, the lumen comprising a distal section and a proximal section, the distal section of the lumen having a wider diameter than the proximal section of the lumen; a window extending through the side wall of the elongated body and communicating with the lumen, the window being disposed in the vicinity of the intersection between the distal section of the lumen and the proximal section of the lumen and being sized to receive a first object therein; an elongated element extending through the lumen of the elongated body, the elongated element comprising a proximal end and a distal end; and a locking element mounted to the distal end of the elongated element and disposed in the distal section of the lumen; whereby, when the elongated body is disposed in a second object, and a first object extends through the window, and the locking element is thereafter moved proximally, proximal movement of the locking element causes the elongated body to capture the first object to the elongated body, whereby to secure the first object to the second object.

A stitching anchor nail includes an anchor body in a shape of straight tube, a non-circular blade jack formed in and through an axis portion of the anchor body along an axis direction thereof, a thread-in structure at a rear-end part of the anchor body, and a spiral tooth structure formed on a side surface of the anchor body and extending from a rear-end part toward a front end of the anchor body along a spiral direction. The spiral tooth structure is formed with a tooth-in entrance at a front end thereof and has a cross section in a shape of a trapezoid having an included angle ranging from 45 to 55 degree between two side edges of the trapezoid and has a tooth top in a width ranging from 0.4 to 0.7 mm.

Knotless surgical constructs and methods of tissue repairs. A surgical construct can offer both repair and shuttling capabilities to allow for a single pass to load multiple sutures at once. A surgical construct can pass or shuttle multiple repair sutures while making a single pass through or around soft tissue.

A repair suture consists of a strand of suture material formed into a continuous loop. One end of the loop may be thicker than the other. The repair suture may be part of a suture assembly including the repair suture, a linking suture having a looped end and a straight end, and a suture anchor. The suture anchor may have a suture bridge that divides the cross-sectional area of the interior of the anchor into two unequal sections. The suture assembly may be used to create luggage tag configurations for repairing tissue or for attaching tissue to bone. In a double-row method with medial row compression, loose suture ends from the medial row are inserted into a lateral row anchor having a proximal anchor body, a distal tip, and internal locking elements for locking the distal tip to the proximal anchor body.
