Anchor delivery systems include markings on the surfaces of the delivery device which are visually exposed to the user through openings or fenestrations in the anchor, providing visual feedback to the user on the progress of the anchor's insertion. A suture-locking plug is deformable within the anchor tip, thereby enhancing suture entrapment within the tip of the anchor. A compliant component of the handle places the handle components in tension, thereby absorbing built-in axial looseness in the handle. The handle further includes a spin cavity which allows for free spin of the inserter shaft to finalize insertion of the anchor into bone when the anchor has not been fully seated flush with or below the cortical bone surface.

Surgical constructs and methods are provided for securing soft tissue to bone. One exemplary embodiment of a construct is formed from a suture filament and includes two terminal ends of filament and an intermediate portion disposed along at least a portion of a length extending between the terminal ends. The construct can have a first terminal end that is the first terminal end of the filament, and a second terminal end that includes a loop. The loop can be formed by disposing the second terminal end of the filament within a volume of a portion of the intermediate portion of the filament. In some disclosed methods, both terminal ends of the filament can be passed through tissue when performing soft tissue repairs. Various other embodiments of constructs and methods are provided, including constructs having two or more filaments associated with an anchor and methods of using such constructs.

Meniscal repair devices, systems, and methods are provided.

Knots and methods of forming knots made of flexible material for use in a surgical environment are described. The knots include one or more ways to unlock at least a portion of the knot.

Embodiments of the bone anchor assembly (36, 50) described herein have adjustable lengths and therefore accommodate many needs. Therefore, the physician does not need to maintain a multitude of bone anchors having a variety of lengths in order to be prepared for many situations. The bone anchor assembly (36, 50) has an elongated hollow shaft portion (38, 52) formed of multiple shaft segments (46, 58) joined together. The length of the shaft portion (38, 52) is adjusted after the implanting of the bone anchor assembly into the bone by removing shaft segments (46, 58).

An internal bracing system is disclosed for stabilizing a joint such as the knee, shoulder, ankle or the like. The internal bracing system includes an extra-articular tension band mechanism and an anchor assembly therefore. The internal bracing system adds substantial control to unstable joints which is effective in limiting the pathological joint motions and internal slippage. The anchor anchoring assembly designed to affix a tethering device to various bony structures which form a joint, for the purpose of providing stability. The anchor assembly includes an anchor and a set screw. A series of disc structures compressed by the set screw securely holds the tether without binding.

Meniscal repair devices, systems, and methods are provided.

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.
