Patent ID: 8349010

Claim:
A ligament graft fixation system for fixing ligament graft material within a bone tunnel comprising: an expandable fixation member having opposed bone engaging elements disposed about its periphery, the fixation member having a proximal end, a distal end and an expansion plug receiving opening defined in the proximal end, at least one plug retaining element provided in the expansion plug receiving opening; a graft receiving eyelet disposed proximate the distal end of the expandable fixation member; an expansion plug having a diameter greater than a diameter of the expansion plug receiving opening and having an engaging element matable with the plug retaining element wherein forceable insertion of the expansion plug into the expansion plug receiving opening causes an expansion of the expandable fixation member driving the opposed bone engaging elements apart so as to fix the bone engaging elements in a bone tunnel; a pull rod engaged to the expandable fixation member; a push tube abutting the expansion plug; and an actuation element engaged to the pull rod and the push tube, the actuation element providing relative movement between the pull rod and the push tube to forceably insert the expansion plug into the expandable fixation member.
