  • Patent number: 5425767
    Abstract: An anchor for an artificial ligament (1) in a bone (2). The anchor comprises a Y-shaped socket (3) having first and second arms (5, 6) configured at an acute angle with respect to each other. The first arm is sized to receive the ligament and has cross-grooves (15) for gripping the ligament. A bullet shaped clamp element (4) is rotatably mounted to the second arm. The clamp element also has grooves that directly contact the ligament to apply an oblique force against the ligament. The clamp element and the cross-grooves in the first arm completely surround and compress the ligament to frictionally secure the ligament to the socket. This configuration distributes the overall pressure so that the specific pressure at any one point is reduced.
