Abstract:
1. A graft fixation device comprising: a sheath having a sheath body that defines an inner longitudinal bore, wherein the sheath body includes a proximal end, a distal end and a side wall; and a member for receipt within said bore, said member being a tapered threaded screw, wherein said sheath body comprises a plurality of longitudinally spaced projections movably connected to said sheath body and a plurality of apertures associated with the plurality of longitudinally spaced projections to allow the plurality of longitudinally spaced projections to move radially out of the sheath body and through an associated aperture, and wherein said projections are hinged on one side so as to be displaceable radially outwardly relative to said sheath body and through the associated aperture upon receipt of said member within said bore, wherein each of the plurality of longitudinally spaced projections comprises a graft engaging portion terminating in a pointed tip and a connecting portion connecting the graft engaging portion to the sheath body, each connecting portion defining a surface which faces towards the proximal end of the sheath body and is arranged so that, upon insertion of the threaded screw into the longitudinal bore, the threaded screw contacts the surface of each connecting portion of the plurality of longitudinally spaced projections, and wherein said side wall is tapered radially inwardly from said proximal end to said distal end, and said distal end has a rounded distal end wall to allow sliding of the graft fixation device between graft strands when the graft fixation device is inserted into a bone tunnel, the rounded distal end wall defining a central circular distal opening and a plurality of equiangularly spaced longitudinal slots.
