Publication number: 20240023997Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A bone anchor is provided. The anchor can include a bone fastener. The bone fastener can include a head and a second end adapted to engage an anatomy. The bone fastener can extend along a longitudinal axis. The anchor can also include a coupling arrangement coupled to the head of the bone fastener so that the bone fastener is rotatable about the longitudinal axis to define a first plane of motion. The anchor can further include a saddle, which can be coupled to the coupling arrangement. The saddle can be movable relative to at least one of the bone fastener and the coupling arrangement to define a second plane of motion.Type: ApplicationFiled: October 2, 2023Publication date: January 25, 2024Inventors: Christopher Shaffrey, Matthew L. Keiser, Laurie G. Sanders, Gretchen Dougherty Shah

Patent number: 10376289Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A cross connector system for use during a spinal fixation procedure is provided. The system includes at least one bridge defining a coupling bore and having a pair of downwardly extending arms for coupling to a first bone engaging member. The system includes a contoured bar having a first end offset from a second end, and a bore having a central axis. The system includes an expansion ring received within the bore, and a locking device received through the expansion ring and the coupling bore. The locking device is operable in a first state in which the contoured bar is movable about the central axis of the bore and in a second state in which the contoured bar fixed relative to the central axis of the bore.Type: GrantFiled: December 5, 2017Date of Patent: August 13, 2019Assignee: Zimmer Biomet Spine, Inc.Inventors: Matthew L Keiser, Laurie G Sanders, Scott Harrington

Patent number: 10213217Abstract: An adjustable drill depth guide includes a first sleeve, a second sleeve and a stop member. The first sleeve includes a longitudinal axis and defines a helical slot disposed about the longitudinal axis. The second sleeve is concentrically arranged relative to the first sleeve and is axially adjustable relative to the first sleeve for adjusting a length of the adjustable drill depth guide. The stop member extends radially from the second sleeve and is disposed in the helical slot. The stop member is selectively received at various positions along the helical slot to positively locate the second sleeve relative to the first sleeve in the axial direction.Type: GrantFiled: September 29, 2017Date of Patent: February 26, 2019Assignee: EBI, LLCInventors: Matthew L Keiser, Scott Harrington
