FLEXIBLE TIBIAL SHEATH
First Claim
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 side wall 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 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.

Abstract
A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.

10. A graft fixation device for fixing a graft member within a bone tunnel, the device comprising:
an expandable sheath having an inner lumen extending between an open proximal end and a substantially closed distal tip, at least one sidewall of the expandable sheath having a substantially concave outer surface extending between the proximal end and the distal tip and configured to seat a graft therein, the concave outer surface being configuration to radially expand toward a circular geometry when a sheath expander is disposed within the inner lumen of the expandable sheath to thereby fix a graft member within a bone tunnel. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
