Abstract

A device for securing a graft in a bone tunnel includes an anchoring member having a graft supporting surface. The anchoring member is configured to be positioned within the bone tunnel distal of an interference member with the graft retained by the graft supporting surface and extending proximally from the anchoring member. The anchoring member has an engaging surface for engaging a distal end of the interference member to limit movement of the graft relative to the interference member.

Independent Claims | See all claims (31)

  1. 1. A device for securing a graft in a bone tunnel, comprising: an interference member configured to be positioned within the bone tunnel; and an anchoring member including a graft supporting surface, the anchoring member being configured to be positioned within the bone tunnel distal of the interference member with the graft retained by the graft supporting surface and extending proximally from the anchoring member, the anchoring member having an engaging surface for engaging a distal end of the interference member to limit movement of the graft relative to the interference member.
  2. 3. A device for securing a graft in a bone tunnel, comprising: an anchoring member including a graft supporting surface, the anchoring member being configured to be positioned within the bone tunnel distal of an interference member with the graft retained by the graft supporting surface and extending proximally from the anchoring member, the anchoring member having an engaging surface for engaging a distal end of the interference member to limit movement of the graft relative to the interference member, wherein the engaging surface comprises an end face of the anchoring member, and wherein the end face includes a coupling member configured to interface with the interference member.
  3. 9. A device for securing a graft in a bone tunnel, comprising: an anchoring member including a graft supporting surface, the anchoring member being configured to be positioned within the bone tunnel distal of an interference member with the graft retained by the graft supporting surface and extending proximally from the anchoring member, the anchoring member having an engaging surface for engaging a distal end of the interference member to limit movement of the graft relative to the interference member, wherein the anchoring member is a generally planar structure including four sides.
  4. 17. A device for securing a graft in a bone tunnel, comprising: an anchoring member including a graft supporting surface, the anchoring member being configured to be positioned within the bone tunnel distal of an interference member with the graft retained by the graft supporting surface and extending proximally from the anchoring member, the anchoring member having an engaging surface for engaging a distal end of the interference member to limit movement of the graft relative to the interference member, wherein the anchoring member defines a bore for receiving a guide wire.
  5. 21. An anchoring member for securing a graft in a bone tunnel, comprising: a generally planar structure including a first side, an opposing second side, a distal end, and a proximal end face, the first side defining a first indentation for receiving the graft and the second side defining a second indentation for receiving the graft, the end face including a, protruding nib configured to fit within an opening in an end of an interference member, the structure defining a bore for receiving a guide wire, the anchoring member being configured to be positioned within the bone tunnel distal of an interference member with the protruding nib interfacing with the interference member and with the graft looped around the distal end of the structure and retained in the first and second indentations, the anchoring member limiting movement of the graft relative to the interference member.
  6. 22. A method for securing a graft in a bone tunnel, comprising: providing an anchoring member including a graft supporting surface, looping the graft over the anchoring member such that the graft is retained by the graft supporting surface, inserting the anchoring member and graft into the bone tunnel, and inserting an interference member into the bone tunnel adjacent the graft and proximal of the anchoring member so that the anchoring member engaging a distal end of the interference member to limit movement of the graft relative to the interference member.
  7. 29. A device for securing a graft in a bone tunnel, comprising: an anchoring member including a graft supporting surface, the anchoring member being configured to be positioned within the bone tunnel with the graft retained by the graft supporting surface and extending proximally from the anchoring member, the anchoring member defining a first bore of a first diameter, an interference member defining a second bore of a second diameter larger than the first diameter, and a guide wire including a first region and a second region of a different diameter than the first region, the first and second regions of the guide wire defining a shelf therebetween, the diameter of the second region being larger than the diameter of the first bore, the first region being insertable into the first bore with the shelf abutting the anchoring member, and the interference member being insertable over the guide wire to abut the anchoring member.
  8. 31. A device for securing a graft in a bone tunnel, comprising: an anchoring member including a graft supporting surface, the anchoring member being configured to be positioned within the bone tunnel with the graft retained by the graft supporting surface and extending proximally from the anchoring member, the anchoring member defining a bore, and a guide wire including a first region and a second region of a different diameter than the first region, the first and second regions of the guide wire defining a shelf therebetween, the diameter of the second region being larger than a diameter of the bore, the first region being insertable into the bore with the shelf abutting the anchoring member.
