Abstract:
1. A material fixation system, comprising: an implant comprising a body having a distal end and a proximal end, which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone; a first member on said body which is deployable outwardly to engage adjacent bone for anchoring said implant in place in the tunnel, the first member having engaging surfaces which extend outwardly relative to remaining portions of the first member; and a second member on said body and spaced axially from said first member, which is deployable outwardly to engage tissue material to be fixed within said tunnel, and to move the tissue material outwardly into contact with the tunnel walls, the second member having engaging surfaces which are substantially broader and flatter than the engaging surfaces of the first member, for more effectively compressing the tissue material against the tunnel walls without penetrating the tissue; a third member which is movable to deploy said first member outwardly; and a fourth member having an enlarged portion which is movable to contact inner sides of the engaging surfaces of the second member to deploy them outwardly, so that outer sides of the engaging surfaces of the second member engage the tissue material to move it outwardly into contact with the tunnel walls.
