A method for syndesmosis fixation including at least one suture anchor configured to be implanted into bone and at least one suture assembly configured to extend from the suture anchor and about at least a portion of a fibula when the suture anchor is implanted in a tibia on either side of a fibular notch of the tibia. The suture assembly is selectively adjustable from a non-tensioned condition to a tensioned condition to stabilize and reduce the fibula relative to the tibia.

Surgical devices and methods are provided for anchoring tissue to bone, and more particularly methods and devices are provided for preventing over-insertion of an expander into a sheath of a two-piece anchor. For example, a tendon anchoring system is provided with an anchor assembly and an inserter tool. The anchor assembly includes a sheath with a threaded lumen and a threaded expander screw configured to be threadably disposed within the sheath to cause the sheath to expand outward. The inserter tool includes an elongate outer shaft with a distal end configured to couple to a proximal end of the sheath, and an elongate inner shaft with a distal drive tip configured to engage a proximal end of the expander screw. In one embodiment, the inner shaft can be rotatable relative to the outer shaft to thread the expander screw into the sheath, and the inner shaft can be prevented from rotating relative to the outer shaft when the expander screw is fully threaded into the sheath to prevent over-insertion of the expander screw into the sheath.

An adjustable, locking all-suture anchor assembly includes at least one suture strand and an all-suture anchoring element. The suture strand has a suture first end and a suture second end, wherein the suture first end includes an enlarged capturable structure and the suture second end is free and accessible for manipulation by a medical practitioner. In use, the suture first end is held in or by the all-suture anchoring element through inclusion of the enlarged capturable structure and the enlarged capturable structure functions to anchor the suture first end in relation to the all-suture anchoring element and retain the suture first end in position relative to the all-suture anchoring element when the suture second end is pulled.

A device is for anchoring a suture to a bone. The device includes a suture engaged with an elastically deformable ring biased toward an unstressed state in which an outer diameter of the ring is D. The ring is compressible for insertion through a hole in a bone stabilization device having a diameter smaller than the diameter D.

A catheter device (2) is provided for implanting an anchor (9) into body tissue to attach a line (14) to the body tissue. The catheter device (2) comprises: a housing section (4), (8) extending from a distal end of the catheter device (2) along the length of the catheter device (2) toward the proximal end of the catheter device, the housing section (4), (8) comprising a distal part (8) at the distal end of the catheter device (2) and a proximal part 4 located on the proximal side of the distal part (8). An anchor deployment mechanism (106), (110) is provided at the distal part (8) of the housing section (4), (8) for deployment of the anchor (9) for attachment of the anchor (9) to the body tissue. The anchor (9) is held in its stowed position by the anchor deployment mechanism (106, 110) in the distal part (8) prior to deployment, and the anchor (9) comprises a number of hooks (62) for engagement with the body tissue and having a folded position and an unfolded position, wherein the anchor (9) is made of an elastic material such that the hooks (62) can be elastically deformed into the folded position by application of a constraining force, and will return to the unfolded position when no constraining force is applied, and wherein the hooks (62) are held in the folded position whilst the anchor (9) is in the stowed position within the distal part (8). The distal part (8) of the housing (4), (8) has a non-circular shape (118), (117) for engagement with a corresponding non-circular form (28), (108) of the anchor (9) and/or the anchor deployment mechanism (106), (110), such that when the anchor (9) is held in the distal part (8) movement of the anchor (9) is restrained with respect to rotation of the anchor (9) about a longitudinal axis of the distal part (8) due to engagement between the non-circular shape (118), (117) and the non-circular form (28), (108).

A multi-suture knotless anchor and related method for securing soft tissue, such as tendons, to bone are described. The suture anchor includes a body, a sleeve, and an outer deformable bone locking structure. The bone locking structure has a first low profile configuration for insertion into the bone, and a second larger profile configuration for engaging the bone when actuated. The bone anchor and methods permit a suture attachment that lies beneath the cortical bone surface and does not require tying of knots in the suture.

Devices and methods are provided for identifying a location of a bore in bone when inserting a suture anchor into bone. One exemplary embodiment of a suture anchor includes an elongate cylindrical body having a proximal terminal end surface, a distal terminal end surface, a lumen extending from the proximal terminal end surface to the distal terminal end surface, at least one bone engaging feature formed on an outer surface of the body, and a bore identification feature incorporated as part of the body. In some instances, the bore identification feature results from opposed sides of an outer surface having disparate lengths, with the side having the longer length serving as the bore identification feature. In other instances, the bore identification feature includes a protrusion that extends from, or is part of, the distal terminal end surface. Other exemplary embodiments, as well as methods for identifying a bore in bone, are also provided.

A top locking rotatable suture anchor device secures one or more sutures with the suture anchor device, installed within a bone at a surgical treatment site, providing rotation of the suture while secured within the suture anchor device and providing adjustment to the tension of the suture during the surgical procedure, the suture anchor device including a delivery tool cooperating with the suture device to conduct the installation of the suture anchor device and tensioning of the suture within suture anchor device.

One embodiment is directed to a system for closing a wound created at least partially across a tissue structure wall, comprising: a helical needle; a suture member coupled to the helical needle and configured to be pulled along a helical pattern with helical movement of the helical needle; an outer delivery member rotatably coupled to the helical needle; a drive shaft axially movably coupled to the outer delivery member; and a plurality of suture guide struts projecting distally from the outer delivery member; wherein upon helical insertion of the helical needle relative to the outer delivery member, the helical needle is advanced such that it becomes disposed around the guide struts, such that the guide struts prevent radial migration of the suture as it is helically wound into the tissue structure.

Syndesmotic fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an ankle joint between a tibia and a fibula may include first and second anchors secured to the tibia and a suture configured to wrap around the fibula. The suture may be tensioned to provide a circumferential force around the fibula to stabilize the joint.
