Publication number: 20140296917Abstract: A spinal stabilization system is provided for maintaining preselected spacing and movement between adjacent vertebrae in a spinal column and for providing overall stability thereto. The system includes interlaminar members positioned in the spaces intermediate a first vertebra and the vertebrae positioned immediately above and immediately below and adjacent to the first vertebra. The interlaminar members are operatively connected to one another by an adjustable support structure and cooperate therewith to maintain the preselected spacing between adjacent vertebrae and to provide overall stability to the spinal column.Type: ApplicationFiled: March 13, 2014Publication date: October 2, 2014Inventors: Edward Jeffrey Donner, Christopher Thomas Donner

Patent number: 8845689Abstract: Disclosed are embodiments of a dynamic stabilizer system for dynamically stabilizing the sacrum and at least lumbar vertebra L5. The dynamic stabilizer system may comprise two anchoring members that can be implanted at distinct locations in the sacrum, a mechanical fastener element having two ends and a flexible portion that can be securely fastened on the spinous process of a lumbar vertebra, and two distinct rods, each securing onto the anchoring members and the mechanical fastener element. In some embodiments, the dynamic stabilizer system may further comprise one or more spacers, each interposed between two spinous processes. The mechanical fastener element further comprises features for securing the one or more spacers.Type: GrantFiled: April 24, 2009Date of Patent: September 30, 2014Assignee: Zimmer Spine S.A.S.Inventors: Stephane Douget, Vincent Pointillart

Patent number: 8845688Abstract: A spinal implant device includes a spacer region and an attachment region. The spacer region is adapted to be positioned between first and second spinous processes of first and second vertebral bodies to limit movement of the first spinous process and the second spinous process toward one another. The attachment region attaches to the first spinous process via a fastener that extends substantially along a long axis of the spinous process.Type: GrantFiled: May 13, 2010Date of Patent: September 30, 2014Inventor: Samy Abdou

Publication number: 20140277142Abstract: In some embodiments, a method comprises forming a lumen in a first bone portion and forming a lumen in a second bone portion. The method further includes inserting a portion of a flexible fastening band through the lumen in the first bone portion and through the lumen in the second bone portion, and inserting the portion of the flexible fastening band into a fastener mechanism monolithically formed with the flexible fastening band. The method further includes advancing the portion of the flexible fastening band through the fastener mechanism until the first bone portion and the second bone portion are stabilized.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventors: Jason Blain, Greg Martin

Patent number: 8834482Abstract: A surgical instrument system comprises surgical instruments for use with an implantable interspinous device having at least one pair of wings for securing the implantable device to a spinous process. The instrument system may include a surgical instrument for expanding or spreading the pair of wings to accommodate the spinous process. Further, a surgical instrument may be provided for crimping or compressing the pair of wings against the spinous process for secure attachment of the device to a vertebra. The surgical instruments may be configured similar to pliers and apply force to the pair of wings within a predetermined range so as to avoid damage, weakening or breakage of the pair of wings. The surgical instrument system may also include interspinous devices of differing sizes.Type: GrantFiled: April 27, 2007Date of Patent: September 16, 2014Assignee: Paradigm Spine, LLCInventors: Frank T. Trautwein, Ralf Riesinger

Patent number: 8821547Abstract: A spinous process implant with two plates that are connected together with a post. The implant is configured for each plate to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. One or both plates may be movable along the length of the post to accommodate different anatomies such as for relatively wide or thin spinous processes. The post includes an enlarged head at a first end to prevent the first plate from disassociating from the post in a first direction. The post also includes a boss at a second end to prevent the second plate from disassociating from the post in a second direction. Methods of attaching the implants to the spinous processes are also disclosed.Type: GrantFiled: November 1, 2010Date of Patent: September 2, 2014Assignee: Warsaw Orthopedic, Inc.Inventors: Randall F. Dryer, Greg C. Marik, Charles Schulte Sullivan, III, Steven D. DeRidder
