Systems and methods for orthopedic repair
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.
Fixation Member With Separate Eyelet And Methods Of Use Thereof
In one embodiment of the present disclosure, an implant system for securing tissue to bone, including a first fixation member releasably engaged to a first inserter, the first fixation member having a throughbore adapted to accept a filament therethrough and a cannulation extending from a proximal end of the first fixation member to a distal end of the first fixation member, the first inserter positioned through the cannulation and having a distal tip extending distally beyond the distal end of the first fixation member, and a second fixation member releasably engaged to a second inserter different from the first inserter, the second fixation member having a size capable of being positioned within the bonehole.
Surgical filament assemblies
A suture anchor, and a surgical filament assembly using same, capable of being fixated in a hole formed in a bone of a patient. The suture anchor preferably includes an anchor body having a distal end, a proximal end, a passage extending from the proximal end toward the distal end, at least one feature disposed on the exterior of the anchor to engage bone, and a filament knot patency element disposed within the passage and defining a channel having a sufficient minimum cross-sectional area to allow movement of a portion of a surgical filament therethrough when a removable sliding knot is formed, using the surgical filament, about the filament knot patency element. The surgical filament assembly preferably includes a first filament having a sliding knot removably positioned about the knot patency element, with a shortening limb and a tightening limb each extending from the sliding knot. The sliding knot defines an adjustable capture loop having two legs extending proximally to a bight, one leg transitioning into the shortening limb and passing through the channel of the knot patency element, the shortening limb being accessible to enable a user to shorten the capture loop. The tightening limb enables the user to tighten the sliding knot against an object extending through the capture loop to secure the object to the anchor.
Fracture fixation device
Assemblies for securing fractured bone are provided. The assembly includes a first fixation element, a second fixation element, and an adjustable flexible member construct. The first fixation element having a male or a female sleeve is secured within a first portion of the fractured bone. The second fixation element having the other of the male or female sleeve telescopically received within the one of the male or female sleeve is secured within a second portion of the fractured bone. The adjustable flexible member construct extends between the first and second fixation elements and has at least one adjustable loop coupled to the first fixation element and the second fixation element and a pair of adjusting ends extending through an opening in the first fixation element. The pair of adjusting ends can be pulled to reduce a diameter of the adjustable loop and to compress fragments of the fractured bone.
Fixation member with separate eyelet and methods of use thereof
In one embodiment of the present disclosure, an implant system for securing tissue to bone, including a first fixation member releasably engaged to a first inserter, the first fixation member having a throughbore adapted to accept a filament therethrough and a cannulation extending from a proximal end of the first fixation member to a distal end of the first fixation member, the first inserter positioned through the cannulation and having a distal tip extending distally beyond the distal end of the first fixation member, and a second fixation member releasably engaged to a second inserter different from the first inserter, the second fixation member having a size capable of being positioned within the bonehole.
Ratcheting inserter device and suture anchor arrangement
A ratcheting inserter device for tensioning a knotless suture anchor includes an outer inserter shaft and an inner inserter shaft having a common longitudinal axis. A ratcheting mechanism provided between the inner inserter shaft and the outer inserter shaft permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion at a distal end that is received by an anchor outer sleeve of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection at the distal end that is received by an inner core of the anchor for rotational movement therewith. The ratcheting inserter device rotates the inner core of the suture anchor to spool and tension suture thread. Thereafter, the ratcheting mechanism is disengaged and the inner inserter shaft is forced axially into the anchor outer sleeve.
Methods and apparatus for implanting prostheses
A deployment device for a tissue repair system includes a front delivery assembly that is detachable from a base assembly of the deployment device. The front delivery assembly includes at least one prosthesis and at least one driven assembly that actuates the at least one prosthesis. The base assembly includes a driving assembly that may engage the at least one driven assembly of the at least one prosthesis. The front delivery assembly can be rotated so that the position of a prosthesis in the front delivery assembly is moved in and out of alignment with the driving assembly. A kit of parts may be provided that includes a base assembly as well as two or more detachable front delivery assemblies.
Knotless suture anchor
A suture anchor is disclosed having an outer body with an axial bore which receives and inner body for rotation. Suture passes between the inner body and outer body and rotation of the inner body wraps the suture thereabout locking the suture thereto. Rotation of the inner body also effects radial expansion of at least a portion of the outer body to engage to anchor into a bone hole.
SECURING GRAFT TISSUE IN A BONE TUNNEL AND IMPLEMENTATIONS THEREOF
This disclosure describes embodiments of an anchor with a body configured to expand radially outwardly along its entire length. The anchor includes, but is not limited to, a cylindrical body having a longitudinal axis and an inner surface and an outer surface, the inner surface defining a central bore, the cylindrical body having a slot exposing the central bore, the slot having a helical path around the longitudinal axis, wherein the slot is configured to expand so that the cylindrical body changes from a first state to a second state in response to pressure on the inner surface, and wherein an outer diameter of cylindrical body in the second state is larger than the outer diameter of the cylindrical body in the first state.
BONE ANCHOR
A bone anchor including an outer sleeve defining slots and an inner sleeve including fins extendable radially outward through the slots to engage surrounding cancellous bone. The outer sleeve includes an outward extending flange disposed about an opening defined by the outer sleeve configured to receive a fastener. The flange can seat against cortical bone around an opening sized for the anchor. The anchor can be a suture anchor including the fastener that engages the inner sleeve when installed therein and pushes the fins outward to engage the cancellous bone as the fastener is installed, better securing the anchor to the bone, particularly where the bone is osteoporotic, weak, broken, diseased, and/or compromised. The outer sleeve can include projections between fins to prevent rotation as the fastener is installed. A related method of using the suture anchor is provided to anchor soft tissue with a suture to bone.
