Patent number: 9186185Abstract: A bone anchoring device including a clamping device and a flexible band configured to be secured a vertebra. The clamping device includes a base member and an upper member configured to be secured together with a fastener. The flexible band is configured to be passed around a bone portion and through a passage of the base member to position the flexible band between a clamping surface of the base member and a clamping surface of the upper member. The flexible band is tensioned to urge the clamping device against the bone portion and then clamped between the clamping surfaces of the base member and the upper member. A stabilization member of a vertebral stabilization construct may be secured to the vertebra with the bone anchoring device without invasively altering or impairing the structural integrity of the vertebra.Type: GrantFiled: November 19, 2013Date of Patent: November 17, 2015Assignee: Zimmer Spine, Inc.Inventors: Hugh Hestad, Kris Pauna

Publication number: 20140148858Abstract: A transverse connector for coupling between first and second vertebral anchors of a spinal stabilization system. The transverse connector includes a first coupling assembly proximate a first end, a second coupling assembly proximate a second end, a first fastener having external threading configured to threadably engage an internal threaded portion of a housing of the first vertebral anchor, and a second fastener having external threading configured to threadably engage an internal threaded portion of a housing of the second vertebral anchor. Each of the first and second fasteners includes a spherical upper surface, such as a spherically concave upper surface. A spherical surface of each of the first and second coupling assemblies mates with the spherical upper surface of the respective fastener to provide multi-axial rotation of the transverse connector relative to the housings to permit a desired orientation of the transverse connector.Type: ApplicationFiled: January 27, 2014Publication date: May 29, 2014Applicant: Zimmer Spine, Inc.Inventors: Jack Dant, Christopher Bargsten, Peter Schulte, Hugh Hestad, Brad Kessler
