Patent ID: 8562680

Claim:
A graft ligament anchor system for fixing a graft ligament within a bone tunnel having a circumferential wall and an opening, comprising: a graft ligament fixing element for disposition within the bone tunnel, the graft ligament fixing element having a plurality of side wall portions configured to contact a graft ligament portion when the graft ligament is placed in the bone tunnel, the side wall portions including at least two concavities extending longitudinally and configured to nest graft ligament portions when a graft ligament is placed in the bone tunnel; a graft ligament, the graft ligament being in contact with the side wall; and a locking element configured for placement within the bone tunnel and to engage the graft ligament fixing element, the locking element being separated from the graft ligament by the graft ligament fixing element; wherein a first side and a second side of the side wall portions are deformable and movement of the locking element causes a change in shape in the first side and the second side; wherein the locking element and graft ligament fixing element are further configured so that movement of the locking element urges the side wall of the graft ligament fixing element, and hence the graft ligament, toward the circumferential wall of the bone tunnel so as to secure the graft ligament to the circumferential wall.
