A graft ligament anchor includes a tubular body having a bore therethrough and proximal and distal ends. A flange is attached to the tubular body at the proximal end thereof and extends radially outwardly beyond the tubular body. A deformable wall is disposed in the tubular body bore and defines, at least in part, a chamber for retaining the graft ligament therein. An expansion device is configured for insertion into the tubular body axially of the tubular body, and for impinging upon the deformable wall to press the deformable wall, and hence the graft ligament received in the chamber, toward a wall of the bore, whereby to fix the graft ligament in the tubular body.

Graft ligament anchor and method for attaching a graft ligament to a bone

A fixation screw, graft ligament anchor assembly, and method for fastening a graft ligament in a bone tunnel. The screw comprises an elongated shank having a distal end and a proximal end, and a central axis extending from the distal end to the proximal end. Screw threads are disposed on the shank and extend from the distal end to the proximal end. The proximal end defines an end plane disposed transversely to the axis and at an angle thereto other than a normal angle.

A graft ligament anchor comprises a graft ligament engagement member disposed in an opening in a bone, the graft ligament engagement member being arranged to receive a graft ligament alongside the engagement member, and a locking member for disposition in the opening, and at least in part engageable with the graft ligament engagement member. Movement of the locking member in the opening causes the locking member to urge the engagement member, and the graft ligament therewith, toward a wall of the opening, to secure the graft ligament to the wall of the opening. A method for attaching a graft ligament to a bone is also provided.

A graft ligament anchor comprises a graft ligament engagement member disposed in an opening in a bone, the graft ligament engagement member being arranged to receive a graft ligament alongside the engagement member, and a locking member for disposition in the opening, and at least in part engageable with the graft ligament engagement member. Movement of the locking member in the opening causes the locking member to urge the engagement member, and the graft ligament therewith, toward a wall of the opening, to secure the graft ligament to the wall of the opening. A method for attaching a graft ligament to a bone comprises providing an opening in the bone, inserting the graft ligament and a graft ligament engagement member in the opening, with the graft ligament disposed alongside a first portion of the engagement member, and inserting a locking member in the bone alongside a second portion of the engagement member, the locking member being separated from the graft ligament by the graft ligament engagement member. The method further comprises moving the locking member to cause the locking member to engage the graft ligament engagement member to urge the graft ligament engagement member, and the graft ligament therewith, toward a wall of the opening to secure the graft ligament to the wall of the opening.

A graft ligament anchor comprises a ligament engagement member in the form of an expandable elastomeric sleeve of substantially cylindrical shape for disposition in an opening in a bone alongside of a portion of a ligament, and a locking member for disposition in the engagement member . Movement of the locking member in the engagement member causes the locking member to expand the engagement member and thereby urge, the ligament toward a wall of the opening so as to secure the ligament to the wall. A method for attaching a graft ligament to a bone comprises providing an opening in the bone, inserting the ligament and a ligament engagement member in the opening, with the ligament disposed alongside the engagement member, inserting a locking member in the engagement member and moving the locking member to engage the engagement member to urge the engagement member, and the ligament, toward a wall of the opening to secure the ligament to the wall.

A graft ligament strand tensioner includes a frame member for slidingly retaining loops of sutures extending from graft ligament strands. The tensioner further includes a collar portion, and is provided with a handle having a core portion on which the collar portion is disposed for axial movement, and a grip portion. The tensioner still further includes a spherical member connected to the handle and having rounded surfaces facing the collar portion. The collar portion is tiltingly movable on the spherical member rounded surfaces when manipulation of the handle, to pull sutures on the frame member taut, causes the collar portion to engage the spherical member rounded surfaces. The sliding retention of the sutures and the tilting movement of the collar portion provide substantial equalization of tension in the sutures and thereby the graft ligament strands.

Graft ligament strand tensioner

A method and apparatus of making repairs with graft ligaments. In one form, the method for graft ligament reconstruction comprises (i) harvesting a graft ligament consisting entirely of soft tissue; (ii) compacting the graft ligament through compression so as to significantly reduce the cross-sectional area and increase the density of the collagen material of the graft ligament; and (iii) deploying the compressed graft ligament in the human body. In another form, the apparatus for graft ligament reconstruction comprises a graft ligament having a given diameter and a given cross-sectional area; and a compacting instrument having at least one surface to contact the graft ligament and to decrease the given cross-sectional area of the graft ligament to a reduced cross-sectional area, whereby the graft ligament with the decreased cross-sectional area may be positioned within a bone tunnel having a cross-sectional area smaller than the given cross-sectional area of the graft ligament in its original state.
