  • Publication number: 20230097453
    Abstract: Devices and methods for reinforcing tissue grafts are described herein. In one embodiment, an implant is described that includes a proximal end portion having a through-hole formed therein, a distal end portion, and a reinforcing insert disposed in the through-hole. The insert includes a proximal face, a distal face opposed to the proximal face, a first upper surface extending between the proximal and distal faces and having a generally convex shape that abuts against at least a portion of a sidewall of the through-hole, and a second lower surface extending between the proximal and distal faces and having a generally concave shape. The second lower surface and portions of the sidewall of the through-hole not abutted by the first upper surface form a reinforced through-hole of the implant.

  • Publication number: 20210045861
    Abstract: An insertion device includes an elongate member and a stylet. The elongate member has a proximal end portion, a distal end portion, and defines a lumen therethrough. The stylet has a distal end portion, a proximal end portion, and is slidably coupled to the elongate member. The stylet is configured to move from a first position to a second position with respect to the elongate member. The distal end portion of the stylet is configured to removably couple a mesh carrier thereto. A portion of the distal end portion of the stylet is disposed outside of the lumen of the elongate member when the stylet is in its first position and is disposed within the lumen when the stylet is in its second position.

  • Patent number: 9724171
    Abstract: Devices, systems, and methods are provided for gauging a bone tunnel. In one exemplary embodiment, a graft repair system can include an elongate pin, an elongate pusher shaft configured to be positioned over one opposed end of the pin when the pin is positioned within a bone tunnel, and a gauge member configured to be positioned over another opposed end of the pin when the pin is positioned within the bone tunnel. When the pusher shaft abuts the bone adjacent one of the open ends of the bone tunnel and the gauge member abuts the bone adjacent the other open end of the bone tunnel, an indicator mark on the pin can be visible through one or more windows formed in the gauge member. The indicator mark's position relative to each of the one or more windows can indicate one or more characteristics related to the bone tunnel.
