Patent ID: 7309355

Claim:
A graft fixation device for fixing a graft member within a bone tunnel, the device comprising: a bioabsorbable radially expandable sheath having a slot-free distal tip with at least two sidewalls extending proximally therefrom and defining a central lumen, each sidewall having a substantially concave outer surface adapted to seat a graft member, and each sidewall being at least partially separated by a longitudinally oriented opening extending from a proximal end along a substantial length of each sidewall and terminating at a position just proximal to the distal tip; and a bioabsorbable sheath expander adapted to be disposed in the central lumen of the radially expandable sheath and configured to deform the concave outer surface of the sidewalls toward a circular geometry to radially expand the sheath so as to fix the graft member within a bone tunnel.
