<p>A novel suture anchor installation tool which in use, the suture (405) is first attached to the suture anchor (105), and then the suture anchor is attached to the elongated member (610) in the foregoing manner. Then the first end of the elongated member is pressed into a predrilled hole (515) in the bone (510), forcing the suture anchor in ahead of it. As the suture anchor is pressed into the bone, its barb (115) engages the side wall (505) of the bone and is forced to retract backwards into the elongated member's slot (635) so that it extends somewhat parallel to the elongated member. When the suture anchor bottoms out in the bone hole (515), and the elongated member is thereafter withdrawn, the barb's engagement with the bone wall will cause the suture anchor to separate from the elongated member, leaving the suture anchor (and its attached suture) anchored securely in the bone.</p> |
