The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.

A method for attaching a graft ligament to a bone comprises providing an opening in the bone, inserting the ligament and a ligament engagement member in the opening, with the ligament disposed alongside the engagement member, inserting a locking member in the engagement member and moving the locking member to engage the engagement member to urge the engagement member, and the ligament, toward a wall of the opening to secure the ligament to the wall.

  • Publication number: 20080161806
    Abstract: A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.

  • Patent number: 7279008
    Abstract: A sheath for organizing soft tissue includes a first tube having a flexible body sized and shaped to receive a fixation device, and a second tube coupled to the first tube having a flexible body sized and shaped to receive a soft tissue graft. A method for implanting soft tissue in a bone tunnel includes coupling a soft tissue graft to a sheath assembly; and positioning the sheath assembly relative to the soft tissue graft based on a measured depth of a bone tunnel. A set of surgical devices for implanting soft tissue grafts in a bone tunnel includes a sheath assembly, a measurement device for measuring the depth of the bone tunnel, a securing element configured to secure the sheath assembly to the soft tissue graft at a position determined by the measured bone tunnel depth, and a tensioning device configured to organize a plurality of soft tissue grafts.
