  • Patent number: 10426537
    Abstract: A method and instrument for tensioning a flexible tie used for fastening an implant on a bony element by forming a first loop around it. In some embodiments, the instrument comprises a shaft having a distal end configured for contact with a rod, a moving part slidably engaged with the shaft, a holder connected to the moving part and configured to hold an end of the flexible tie, and a tension control member comprising a trigger that pivots relative to the moving part. In some embodiments, the method comprises coupling the end of the flexible tie to the instrument and squeezing the trigger to shorten the first loop of the flexible tie around the bony element, causing the moving part and the holder holding the end of the flexible tie to move in translation away from the distal end of the shaft, thereby exerting tension on the flexible tie.

  • Patent number: 9949778
    Abstract: A spinal implant can be fastened on a bony element of a patient via a flexible tie. In some embodiments, the spinal implant has two jaws, each having a recess and an opening. The recess is configured to receive a portion of a rod. A portion of the flexible tie is passed through the opening and between a wall of the recess and a surface of the rod to form a loop that can be placed around the bony element. The two jaws are hinged at one end and engaged at the opposite end via a locking member. The locking member can be adjusted to simultaneously hold the jaws together in a fixed position relative to the rod and lock the flexible tie, which has been properly tensioned, in translation relative to the spinal implant.

  • Patent number: 9848921
    Abstract: Embodiments disclosed herein provide a method of placing a vertebral fixing system on a vertebra. The vertebral fixing system comprises a connecting part with members forming a space into which a rod may be inserted. The members are moveable relative to each other. A portion of a ligature may be passed through the connecting part to form a loop extending from the connecting part. When the rod is inserted in the space between the members, the ligature may be tensioned against the rod. The members of the connecting part may be driven together to hold the ligature in place. An adjustable locking means may be utilized to fix simultaneously in position the connecting part relative to the rod and at least one portion of the ligature relative to the connecting part, so as to prevent relative displacement of the rod and the vertebra in opposite directions.

  • Patent number: 9717536
    Abstract: A vertebral fixing system suitable for being mounted on a vertebra of the spine for connecting it to a rod. The system includes: a connecting part suitable for being connected to the rod, a flexible ligature of elongate shape having two free ends suitable for connecting together the connecting part and at least a portion of a vertebra and/or a rib, and an adjustable locking member mounted on the connecting part. The connecting part defines at least one passageway for passing the ligature in such a manner that two distinct strands of the ligature can be engaged in the passageway so that the two strands of the ligature define a first ligature portion forming a loop extending from one side of the connecting part, and second and third ligature portions extending from the other side of the connecting part.

  • Patent number: 8870870
    Abstract: A vertebral fixing system comprising a connecting part with two longitudinal elements coupled to each other at a first end and having mutually facing recesses for receiving a rod. A portion of a flexible ligature extends through orifices of the two longitudinal elements to define a loop opposite two free ends of the flexible ligature. The two longitudinal elements are engaged at a second end of the connecting part via a locking means. When the two longitudinal elements of the connecting part are locked at the second end of the connecting part, two strands of the flexible ligature are pinched between the rod and a wall of the mutually facing recesses of the two longitudinal elements of the connecting part, preventing the flexible ligature from moving in translation relative to the connecting part.
