1. A system for drilling a tunnel through bone, said system comprising:
a drill assembly comprising:
an elongated shaft having a proximal end and distal end, the distal end of the shaft configured to drill a first tunnel through a bone; and
a cutting member disposed adjacent the distal end of the shaft, the cutting member configured to move between a closed position and a deployed position to drill a second tunnel through the bone, a diameter of the second tunnel selected to be greater than a diameter of the first tunnel; and
a sheath slidably disposed over the shaft, the sheath including a stop member extending radially from an outer surface of the sheath, the sheath configured to slide into the first tunnel such that the stop member contacts a surface of the bone.
