  • Patent number: 10426538
    Abstract: A spinal stabilization system may be formed in a patient. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient. Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. Extenders may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The extenders may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars. An adjuster may be used in conjunction with the extenders to change a separation distance between the bone fastener assemblies.

  • Patent number: 10154862
    Abstract: Embodiments described herein provide systems and methods for vertebral reduction using sleeves detachably coupled to collars of bone fasteners. The reduction can be performed during a minimally invasive procedure for implanting spinal stabilization systems. A sleeve can include internal threads that match threads on the respective collar to form a continuous set of threads. Threads on a closure member can be engaged with the threads on the sleeve and the closure member turned to translate the closure member along the sleeve. The closure member can be used to push a rod relative to the collar to which the sleeve is attached to cause a vertebral body to move.

  • Publication number: 20180092665
    Abstract: Embodiments disclosed herein provide compression/distraction methods and tools useful for fitting a spinal stabilization system in a patient through minimally invasive surgery. The spinal stabilization system may comprise screws anchored in vertebrae. The vertebrae may need to be compressed or distracted. One embodiment of an instrument disclosed herein may comprise a shaft for engaging one of the screws through an extender sleeve. A driver may engage another screw through an opening of the instrument. Through this engagement, a surgeon may use the rack and pinion of the instrument to compress or distract one or more levels of the vertebrae in a parallel motion, which can be advantageous clinically in certain situations.

  • Publication number: 20170100164
    Abstract: In some embodiments, a spinal stabilization system may be formed in a patient using quick-connect sleeve assemblies. Each quick-connect sleeve assembly can be coupled to a bone fastener assembly in a fast and intuitive way. In one embodiment, a quick-connect sleeve assembly has a detachable member and a movable member. Both members engage a collar of the bone fastener assembly. In one embodiment, the engagement can be locked via one or more locking features to facilitate screwing a bone fastener of the bone fastener assembly onto a vertebral body in a minimally invasive surgical procedure. Each quick-connect sleeve assembly has a low profile and is particularly shaped for minimally invasive entry.
