Abstract:
1. 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 closed 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, wherein the substantially concave outer surface of each sidewall is configured to deform toward a substantially convex outer surface so that the expandable sheath achieves a substantially circular geometry when a sheath expander is disposed within the central lumen of the radially expandable sheath so as to fix a graft member within a bone tunnel.
