  • Publication number: 20150142110
    Abstract: Systems for single tunnel, double bundle anterior cruciate ligament reconstruction include implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. The instruments are also used to exercise and insert the ligament graft constructs. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on a single femoral tunnel, single or double tibial tunnels, and one or more ligament grafts.

    Abstract: The invention relates to an implantable prosthetic device, a patch, for the repair of connective tissue in an animal or a human. In one embodiment, a biocompatible repair patch (10) for repair of human or animal tissue is disclosed which comprises a tensile load-bearing component in the form of a pre-formed array (13) of a looped configuration in a desired pattern and having at least one return end, said array being formed of an elongate filamentary material; and a base layer (11) of non-woven fibrous material. The pre-formed array is attached to one surface of the base layer so that the pre-formed array retains its configuration while being handled during surgery. The at least one return end serves to receive a suture or the like to attach the patch to tissue. The fibres of the base layer are entangled with the looped configuration so as to attach the array to the base layer and substantially to maintain the desired pattern.

    Abstract: An implantation assembly (16) comprises a guide element (22) for a ligament (18); a pulling element (24) comprising a pulling loop (26); and a manipulating loop (28). The guide element has a pulling aperture (36) towards a leading end (32), a manipulating aperture (38) towards a trailing end (34), and a connecting arrangement (40) for the ligament. The pulling and manipulating loops pass through the respective apertures. When the guide element emerges from a bone tunnel mouth, the manipulating loop is used to manipulate the guide element to a position where it overlies the tunnel mouth. The manipulating loop is secured to the pulling element and arranged such that a tensile load can be applied to the pulling element without generating a tensile load in the manipulating loop which could otherwise cause the guide element to be manipulated towards the anchoring position during passage along the bone tunnels.

  • Publication number: 20150057750
    Abstract: Techniques and reconstruction systems for ligament repair and fixation. A bone tendon graft is prepared by folding the bone block over a suspensory fixation device (for example, a knotless suture construct such as a knotless, adjustable, self-cinching suture loop/button construct, a suture, crosspin, or screw, etc.). A flexible strand is then used to suture the bone plug to the tendon so that the overall graft is shortened significantly and the suspensory fixation device is securely attached. The technique does not require passage of the suspensory fixation device through the bone block which makes the graft passage easier since the graft is pulled from the tip. The technique also allows shortening of the overall graft.

The clamp exhibits a tapered or non-linear three dimensional shape to accommodate the folded over ligament end-loop and can be constructed of a plastic or other suitable material, and includes a split location such as permitting the clamp to be forcibly manipulated in position around the looped end of the ligaments, following which they are snap-fit or tightened such that inner facing knurled patterns engage and inwardly compress the overlapping ligament bunches. The screw is pre-positioned during the initial folding of the ligament ends and is fixedly maintained about the inner looped end following installation of the clamp. The shaft portion of the screw can exhibit varying thread profiles, promoting the creation of gripping forces when installed within the user's bone.

  • Patent number: 8870955
    Abstract: An anterior cruciate ligament (ACL) surgical repair technique involves the use of a single femoral and tibial tunnel and an implant that separates and positions two distinct bundles. This allows for the surgeon to create a more anatomic reconstruction with a procedure that is less technically demanding, can be performed using a transtibial or anteromedial approach, minimizes tunnel widening, and decreases operative time. The result is a strong fixation option for soft tissue grafts, with circumferential graft compression at the aperture, high pull-out strength, and ease of use. The graft bundles are positioned in a more anatomic orientation through the above noted single femoral and tibial tunnel.

  • Patent number: 8870877
    Abstract: A graft fixation device comprising a sheath having a body that defines an inner longitudinal bore and a member for insertion within the bore. The sheath includes at least two projections movably connected to the sheath body by a distal hinge. The distal hinge causes the projection to pivot inwardly as the sheath is placed in a bone tunnel, and to be displaceable radially outwardly of the sheath body upon insertion of the member within the bore.

  • Patent number: 8864797
    Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.

  • Patent number: 8858634
    Abstract: Methods and devices are disclosed for the attachment of a soft tissue structure (e.g., tendon or ligament) to bone or a prosthetic implant. In one form, the device includes a clamp having a convex tissue engaging surface. A fastener compresses the soft tissue between the tissue engaging surface and the bone or the prosthetic implant. In another form, the device includes a second clamp comprising a porous metallic material. The second clamp has a first surface, a concave tissue engaging surface opposite the first surface, and a throughhole for a fastener. The second clamp is placed adjacent the bone, the soft tissue is placed adjacent the second clamp, and the first clamp is placed adjacent the soft tissue. The soft tissue is compressed between the convex tissue engaging surface of the first clamp and the concave tissue engaging surface of the second clamp using the fastener.

  • Patent number: 8852214
    Abstract: Methods and systems are provided for fixating connective tissue to bone. Some aspects include a carrier member having a length, width, and thickness, wherein the length and width are each at least two times greater than the thickness; attachment members extending from the carrier member and that engage connective tissue of an animal; and a bone engaging member extending from the carrier member and configured to attach to a bone of the animal. In some aspects, when the attachment members are engaged with the connective tissue and the bone engaging member is attached to the bone, the connective tissue and the bone are limited in being pulled apart from one another during physiological use of the connective tissue.

  • Patent number: 8845725
    Abstract: A tendon anchoring device may include an implant having a pair of spaced apart legs for straddling a tendon. A push rod removably attached to the implant may be utilized to guide and push a portion of the tendon into a pre-drilled bore in a bone. A fixation member may be slid along the push rod and threadably engage an inner surface of the pre-drilled bore to thereby anchor the tendon to the bone while a force is applied to the push rod. Once the fixation member has been installed, the push rod may be disengaged from the implant and removed from the bore. The implant may remain permanently straddled over the tendon inside of the bore.
