A system for fixing soft tissue within a bone tunnel includes a first
fixation member that is adapted for insertion against a piece of soft
tissue positioned within a bone tunnel, with a portion of the soft tissue
emerging therefrom. The first fixation member has a proximal end and a
distal end. A second fixation member can engage the first fixation member
at its proximal end and also can prevent the first fixation member's
proximal end from passing into the bone tunnel. The proximal end has barbs
for engaging the soft tissue's second portion. Another element is
engageable with the second fixation member for extracting it from
engagement with the soft tissue's second portion.
