A knotless suture anchor may include an anchor body with a proximal end, a distal end, an interior longitudinal passageway, a proximal opening communicating with the longitudinal passageway nearer the proximal end, and a distal opening communicating with the longitudinal passageway nearer the distal end. A first suture portion extends within the longitudinal passageway between the proximal opening and the distal opening, a second suture portion is contiguous to the first portion and extending out of the anchor body, a third suture portion is contiguous to the second portion and extends within the longitudinal passageway proximally to distally, and a fourth suture portion is contiguous to the third portion, extending along the exterior surface distally to proximally. A proximal member may be joined to the anchor body by a frangible connection and may have a proximal member axial passage containing an interference member coaxially aligned with the longitudinal passageway.

Described herein is a deployable anchor that includes a head positionable within or entirely through an interior portion of a bone. While positioned within or entirely through the interior portion of the bone, the head is deployable to frictionally engage the bone and fixate the head relative to the bone. The anchor also includes a cable that is coupled to the head. The cable is configured to be tensioned to a measurable and adjustable tension.

A suture anchor including an outer anchor part and an inner anchor part. The outer anchor part includes a proximal end, a distal end, and an inner surface defining a center bore extending between the proximal end and the distal end. The center bore includes a tapered proximal portion. The inner anchor part includes a tapered outer surface defining a first pair of opposing apertures. Insertion of the inner anchor part into the tapered proximal portion of the outer anchor part enables a suture extending through the first pair of opposing apertures to be coupled to the suture anchor. A taper fit between the tapered proximal portion of the center bore of the outer anchor part and the tapered outer surface of the inner anchor part retains the inner anchor part within the outer anchor part.

An expanding suture anchor in which a distal end of the rigid anchor body includes at least one annular protrusion. A mating deformable cap includes at least one annular slot or ridge that engages the annular protrusion such that the annular slot and annular protrusion are coupled when the deformable cap is pushed or pulled onto the rigid anchor body. The engagement of the annular slot and the annular protrusion may lock the deformable cap and rigid anchor body into a mated position and inhibits distal retraction of the deformable cap from the anchor body.

A suture anchor assembly includes a suture anchor and a suture anchor inserter. The anchor includes a flexible distal tip and a rigid proximal anchor body. The distal tip includes a transverse suture eyelet and a cavity formed in a proximal end of the tip. The anchor body includes a lumen extending between proximal and distal ends of the body. The anchor inserter includes a tubular outer shaft and an inner inserter slidably received therein. The anchor assembly is actuatable to move the anchor tip and inner shaft proximally while the outer shaft and anchor body remain in place, urging the proximal end of the anchor tip against the distal end of the anchor body. The proximal end of the tip is deformable to accommodate at least a portion of the distal end of the anchor body within the anchor tip cavity.

According to some embodiments, an implant for correcting a deformity in or near a joint of a subject includes an implant body having an internal lumen, a suture side hole or window extending through a wall of the implant body and providing access to the internal lumen through an exterior of the implant body, a tension assembly comprising a first bone anchor and a second bone anchor, wherein the first and second bone anchors are configured to be placed on opposite sides of the implant body, and an adjustable suture loop coupling the first bone anchor to the second bone anchor, wherein at least a portion of the at least one adjustable suture loop is positioned within the internal lumen of the implant body.

A device for fixating a suture anchor beyond a hard tissue opening with the aid of a material having thermoplastic properties and energy transmitted to the suture anchor for in situ liquefaction of at least part of the material having thermoplastic properties. The device includes a tool and a suture anchor. The tool has a proximal end suitable for being coupled to an energy source and a distal end suitable for arrangement of the suture anchor including the suture. The distal end includes a distal tool face and an axial channel with a distal mouth located in the distal tool face. The suture anchor has an anchor foot and a thermoplastic sleeve including the material having thermoplastic properties. The anchor foot holds a loop of a suture such that end sections of the suture reach through the thermoplastic sleeve and a portion of the distal tool face.

Methods are disclosed for attaching a suture to a bone. One exemplary method includes passing a portion of a suture through a bone so that a first portion of the suture extends from a first opening in the bone and a second portion of the suture extends from a second opening in the bone, passing the second portion of the suture through a portion of a suture anchor body in a proximal to distal direction, the suture anchor body having a proximal end and a distal end, passing the second portion of the suture alongside an outer surface of the suture anchor body in a distal to proximal direction, and then inserting the suture anchor into the bone through one of the first and second openings, the distal end being inserted first through the opening.

Apparatus for securing a suture to a bone, the apparatus including an anchor configured to have the suture connected thereto; and an inserter for manipulating the anchor, the inserter including a handle; a shaft mounted to the handle and configured to releasably hold the anchor thereto; a retractable sheath movably mounted to the handle, the retractable sheath having a first extended position and a second retracted position, wherein the retractable sheath is disposed coaxially over at least a portion of the anchor when the retractable sheath is in its first extended position, and the retractable sheath is withdrawn from the anchor when the retractable sheath is in its second retracted position; and an outer tube mounted to the handle, the outer tube being disposed coaxially over the retractable sheath.

A method for securing a first object to a second object comprising providing apparatus comprising an elongated body having a lumen; an enlargement; a first elongated element, the distal end of the first elongated element being connected to the enlargement and the proximal end of the first elongated element extending through the lumen; and a second elongated element connected to the first elongated element external to the elongated body; inserting the elongated body into the second object; moving the second elongated element proximally so as to cause proximal movement of the first elongated element so as to cause the enlargement to move into a second portion of the lumen, whereby to laterally expand the elongated body; and securing the first object to the second object with the second elongated element.
