Patent number: 9707019Abstract: 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.Type: GrantFiled: August 11, 2009Date of Patent: July 18, 2017Assignee: Zimmer Spine, Inc.Inventors: Peter Thomas Miller, Charles R. Forton, Bruce A. Riceman, Larry T. Khoo, Reginald James Davis, Michael Scott Hisey

Patent number: 8814914Abstract: Embodiments described herein provide tools and methods for spinal fusion procedures. One embodiment of a tool can be a pedicle access tool that performs the functions of targeting needle, cannula, tap and awl. The cannula of the tool can be used to guide various tools and bone graft or fusion promoting material to a surgical site for a spinal fusion procedure, such as a posterolateral procedure. In other embodiments, a k-wire can be used as the guide.Type: GrantFiled: August 28, 2009Date of Patent: August 26, 2014Assignee: Zimmer Spine, Inc.Inventors: Peter Thomas Miller, Charles R. Forton, Reginald James Davis
