Patent number: 10507119Abstract: A spinal interbody device, system and method can include an interbody device configured to stabilize or otherwise support adjacent vertebrae. The interbody device can include a central opening and can be shaped as a trapezoid as viewed from a position on the central axis located above a superior or upper surface of the interbody device. In addition, the upper surface of the interbody device can include at least one keel or spike to facilitate locking of the interbody device with adjacent vertebrae. The at least one spike can be removable and can be adjustable relative to the superior or inferior surface(s) when installed.Type: GrantFiled: December 19, 2013Date of Patent: December 17, 2019Assignee: AESCULAP IMPLANT SYSTEMS, LLCInventors: Nikolay S.

Patent number: 9114023Abstract: A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The device includes a snap in mechanism for coupling the first piece to the second piece.Type: GrantFiled: April 27, 2012Date of Patent: August 25, 2015Assignee: SpineSmith Partners, L.P.Inventors: Richard Kana, Kevin Dunworth, John Rossman, Larry Khoo, Zachary Smith

Patent number: 9101411Abstract: Fusion of cervical spinal vertebrae with one or more fixation devices can be accomplished with the described tools and methods. For example, a guidewire introducer can include a tubular introducer cannula and a handle. The handle can be angularly offset from the introducer cannula such that positioning of the introducer on the cervical spine does not interfere with a patient's head. A sheath assembly can include inner and outer sheath bodies and a handle. The handle is angularly offset from the sheath bodies such that the sheath assembly can be applied to the cervical spine without interference to the patient's head. The sheath body can be curved or straight. Various tools such as drills, tapping devices, compression tools, and pin release tools can be applied to the cervical spine through the sheath body to apply the fixation device. The tools can include elongate flexible shafts.Type: GrantFiled: April 1, 2011Date of Patent: August 11, 2015Assignee: Interventional Spine, Inc.Inventors: Brad S. Culbert, Larry Khoo, Bob Flower

Patent number: 8070779Abstract: A percutaneous interspinous process device for treating spinal conditions includes a first section, a second section, and a locking mechanism. The first section defines a first lateral surface, a first medial surface and a first lumen extending from the first lateral surface to the first medial surface. The second section defines a second lateral surface, a second medial surface and a second lumen extending from the second lateral surface. The locking mechanism includes an elongate member protruding from the first medial surface of the first section and a medial recess defined in the second medial surface of the second section. The medial recess is configured for securely receiving at least a portion of the elongate member. The elongate member is configured to define a space between adjacent spinous processes and maintain a predetermined distance between adjacent spinous processes.Type: GrantFiled: June 4, 2008Date of Patent: December 6, 2011Assignee: K2M, Inc.Inventor: Larry Khoo

Patent number: 7985242Abstract: 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. 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. A reducer may be used to achieve reduction of one or more vertebral bodies coupled to a spinal stabilization system.Type: GrantFiled: March 23, 2007Date of Patent: July 26, 2011Assignee: Zimmer Spine, Inc.Inventors: Charlie Forton, Robert J.
