Abstract:
A graft fixation device for fixing a graft member within a bone tunnel, the device comprising:a radially expandable sheath having a side wall, at least one structurally weakened fracture region extending longitudinally along a length of the sheath in the side wall, and a central lumen, the radially expandable sheath sized to fit within a bone tunnel so that a graft member may be accommodated between a wall of a bone tunnel and an outer surface of the radially expandable sheath; and a sheath expander disposable in the central lumen of the radially expandable sheath to radially expand the sheath so as to fix a graft member within a bone tunnel; wherein the structurally weakened fracture region is adapted to fracture upon radial expansion of the sheath to allow varying amounts of radial expansion.
