Abstract
Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.
Claims19
A graft fixation device for fixing a graft member within a bone tunnel, the device comprising:
- a radially expandable sheath having proximal and distal ends and a central lumen extending therebetween, the radially expandable sheath having first, second, and third sidewalls defining a substantially triangular cross-sectional shape, the first sidewall having a stop member formed on a proximal-most end thereof, the stop member having a distal-facing surface that is distal to at least a portion of a proximal-most end of the second and third sidewalls, and the stop member being configured to prevent over-insertion of the radially expandable sheath into a bone tunnel;
- and
- a sheath expander disposable within the central lumen of the radially expandable sheath and configured to flex the first, second, and third sidewalls to radially expand the sheath so as to fix a graft member extending along the first, second, and third sidewalls within the bone tunnel,
- wherein the sheath expander and a distal-most end of the radially expandable sheath each include a lumen extending longitudinally therethrough for receiving a guide wire.

- and
- a sheath expander disposable within the central lumen of the radially expandable sheath and configured to flex the first, second, and third sidewalls to radially expand the sheath so as to fix a graft member extending along the first, second, and third sidewalls within the bone tunnel,
- wherein the sheath expander and the radially expandable sheath are formed from a bioabsorbable material.

- and
- a sheath expander disposable within the central lumen of the radially expandable sheath and configured to flex the first, second, and third sidewalls to radially expand the sheath so as to fix a graft member extending along the first, second, and third sidewalls within the bone tunnel.
