  • 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.

  • Patent number: 10130394
    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. The collar may be rotated and/or angulated relative to the bone fastener. Detachable members may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The detachable members 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.

  • 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.

  • Patent number: 9066763
    Abstract: Embodiments of a surgical instrument disclosed herein can include mechanisms for reduction and distraction as well as compression. Some embodiments of the surgical instrument may comprise a reducer knob having a first passage through which a first shaft of a driver is acceptable, a connecting element coupled to the reducer knob and having a second passage through which the first shaft of the driver is acceptable, a compressor handle coupled to the connecting element at a first end and having a through hole, and a common handle coupled to the compressor handle via the through hole and pivots between the reducer knob and the compressor handle. With embodiments of a surgical instrument disclosed herein, surgical personnel can distract and hold vertebrae in a distracted state and perform a reduction without having to switch or add instruments. Some embodiments disclosed herein can be particularly useful for reducing spondylolisthesis during posterior fixation.

  • Patent number: 8728162
    Abstract: Apparatus, systems, and methods for spine surgery employ a guide wire temporarily anchored to a contralateral side of an intervertebral disc. The guide wire establishes a reliable pathway for passage and actuation of cannulated instruments or implants through a small working channel leading to an ipsilateral side of the disc. The guide wire may be disconnected and removed from the disc after use.

  • Patent number: 8623022
    Abstract: Embodiments include a system for manipulating a portion of the spine. A support body provides support for extender sleeves that are coupled to bone screws implanted in bone. The extender sleeves are coupled to the support body in a manner that allows translation and rotation of the extender sleeves relative to the support body. Movement and rotation of the extender sleeves in selected directions can be allowed while movement and rotation in other directions can be inhibited. The extender sleeves can be manipulated to move the bone.

  • Patent number: 8603145
    Abstract: A poly-axial bone fastener assembly having a collar and a bone fastener can be coaxially locked to prevent poly-axial movements of the collar relative to the bone fastener while permitting the collar to rotate about an axis of the bone fastener, thereby combining the functions and advantages of a poly-axial bone screw and a fixed angle bone screw. Some embodiments of a coaxial locking mechanism may include a c-clip with a locking pin, a c-clip with hooks, a split ring with square corners, a pin that spins inside the collar, pins that travel about a neck of the bone fastener, a coaxially locking top that screws into the collar over a head of the bone fastener, and a top nut that threads onto the head of the bone fastener inside the collar to trap a flange of the collar between a shoulder of the bone fastener and the top nut.
