Patent number: 8945225Abstract: A prosthetic spinal disc system is provided. The prosthetic disc system has a nucleus component having an upper surface configured to engage a superior vertebra and a lower surface configured to engage an inferior vertebra, an anchor configured to affix to an anterior surface of at least one of the superior vertebra or the inferior vertebra, and a tether tying the nucleus component to the anchor. In such embodiments, the nucleus component further has a perimeter situated substantially between the upper surface and the lower surface of the nucleus component and the tether is at least partially situated on the perimeter of the nucleus component. In certain embodiments, the upper surface and the lower surface of the nucleus component are configured to allow for implantation of the disc system such that after a discectomy, no preparation of at least one of the superior and inferior vertebrae is necessary.Type: GrantFiled: July 20, 2009Date of Patent: February 3, 2015Assignee: Warsaw, Orthopedic, Inc.Inventors: Craig Squires, Mark Dace, Stanley Palmatier

Patent number: 8911441Abstract: The present application is directed to instruments and methods for preparing a space between vertebral members. One embodiment of the instrument may include an elongated shaft with a proximal end and a distal end. A blade may be positioned at an end of the shaft and may rotate about an axis. The blade may include one or more teeth that include a height and/or contour. During rotation of the blade, the teeth contact and cut into one of the vertebral members. The instrument may also include a depth stop that limits a depth that the teeth can cut into the vertebral member. In some embodiments, the instrument includes a second blade that is configured to cut into the second vertebral member.Type: GrantFiled: October 3, 2008Date of Patent: December 16, 2014Assignee: Warsaw Orthopedic, Inc.Inventors: Mark Dace, Stephen Papadopoulos, Stephen White, Bradley Coates, Greg Marik

Patent number: 8070815Abstract: An intervertebral implant system for positioning between an upper vertebra and a lower vertebra is provided. The implant system comprises an intervertebral implant and a staple. The implant comprises an inferior plate and a superior plate, while the superior plate has a vertebral surface facing the upper vertebra and the inferior plate has a vertebral surface facing the lower vertebra. There are two grooves on at least one vertebral surface extending at an angle outward from a centerline on the vertebral surface as they extend from the anterior portion of the plate toward the posterior portion of the plate. When in use, the staple is associated with the two grooves for maintaining stability of the intervertebral implant and preventing backing out of the intervertebral implant. The staple also has two arms and has a generally rectangular shape prior to use.Type: GrantFiled: August 6, 2008Date of Patent: December 6, 2011Assignee: Warsaw Orthopedic, Inc.Inventors: Kidong Yu, Mark Dace
