Patent number: 10426537Abstract: 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.Type: GrantFiled: March 14, 2018Date of Patent: October 1, 2019Assignee: Zimmer Spine, S.A.S.Inventors: Christian Baccelli, Regis Le Couedic, Keyvan Mazda

Patent number: 10182846Abstract: This disclosure relates to a spinal implant that can provisionally retain a rod in an assembly head without having to first lock the rod relative to the assembly head. The spinal implant has a clip insert structured to retain the rod in the assembly head. The clip insert has a top portion with a cylindrical opening and extending over the cylindrical opening to cover the connection rod in part when the connection rod is engaged in the clip insert. The top portion is deformable by application of force on the connection rod to engage the connection rod with the clip insert. The clip insert and the assembly head are mechanically decoupled and can be fully received within the assembly head. The mechanical forces to which the assembly head is subjected are not transmitted to the clip insert.Type: GrantFiled: November 6, 2014Date of Patent: January 22, 2019Assignee: Zimmer Spine S.A.S.Inventor: Christian Baccelli

Patent number: 9949778Abstract: 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.Type: GrantFiled: June 6, 2011Date of Patent: April 24, 2018Assignee: Zimmer Spine S.A.S.Inventors: Christian Baccelli, Régis Le Couedic, Keyvan Mazda
