  • Patent number: 8852250
    Abstract: The subject invention is a fixation device or anchor intended to secure a graft ligament or other soft tissue repair. The device is designed to be attached to a graft ligament and to secure the graft within a bone tunnel by extending transversely across the opening of the tunnel. In certain procedures the device is intended to pass through a bone tunnel in an orientation generally aligned with the tunnel and then turn transversely. The device has an inherent tendency to rotate upon exiting the tunnel to thereby become automatically transversely aligned with the tunnel and the graft ligament. The rotation is due to a moment automatically created as a resultant of forces applied to the anchor by a pulling-suture via a laterally offset aperture joining the pulling-suture to the anchor.
    Type: Grant
