Ligament bone anchor and method for its use
First Claim
1. A bone anchor comprising a body that includes means for securing said body in a tunnel section formed in a bone mass and includes an axial opening with an end of said opening formed to receive an insertion tool and is configured to receive a clamping means fitted therein;
- a clamping means formed to fit within and be axially movable within said body axial opening so as to move a clamping surface or surfaces towards a surface of said body axial opening and said clamping means is to engage a surface of a suture or shaft means fitted in a said axial opening to clamp said suture or shaft means surface against said surface of said body axial opening;
means for maintaining said clamping means to be movable in said axial opening; and
at least one said suture or shaft means for fitting in said body to pass between said surface or surfaces of said clamping means and said surface of said body axial opening.

Abstract
A bone anchor and method for its use in an arthroscopic and open soft tissue surgical procedure to mount a ligament graft, or the like, under tension and at variable lengths in a tunnel section that is formed through a bone or bones. The bone anchor embodiments of the invention each have a body for mounting into and/or adjacent a bone cortex surface in a tunnel section to allow at least one suture or shaft that has been fitted through the bone anchor, and is attached to the ligament graft to be pulled through the bone anchor. The suture or shaft to pass across a movable clamp fitted within the body to move so as to allow the suture or shaft to be pulled freely through the bone anchor distal, but will clamp against the suture or shaft, prohibiting its being pulled back therethrough. A pulling of the suture or shaft through the seated bone anchor applies a tension and sets a required length to a graft whose opposite end is secured, with the clamp locking against a section of that suture or shaft, to maintain that applied tension. Whereafter, the excess suture or shaft can be cut away, permanently mounting the graft.
