The superior portion of the device is coupled to a superior portion of the spine, and the inferior portion of the device is coupled to an inferior portion of the spine thereby constraining flexion of the spine. The system also includes bone graft for fusing the superior and inferior portions of the spine together. The bone graft is disposed between the superior and inferior portions of the spine, and the tether has a width suitable for holding the bone graft in a mass disposed between the superior and inferior portions of the spine. The tether also has a porosity suitable to allow body fluids to pass therethrough so that the graft material forms a solid mass.Type: ApplicationFiled: August 9, 2013Publication date: December 5, 2013Applicant: Simpirica Spine, Inc.Inventors: Hugues Malandain, Jeffrey Schwardt, Austin F.

Patent number: 8591546Abstract: A spinal implant adapted to be inserted into an interspinous space between adjacent spinous processes includes a proximal section, a central section, and a distal section disposed sequentially along a longitudinal axis. The distal section has feature(s) that allow the implant to be inserted laterally into the interspinous space, such as an approximately helical groove and/or a thread-like structure. The distal tip of the implant tapers inwardly, and may be rounded. The proximal section may include an outwardly extending wing or flange. The implant may include a main body that includes the wing or flange and a spacer slidably mated to the main body through the wing or flange.Type: GrantFiled: December 7, 2011Date of Patent: November 26, 2013Assignee: Warsaw Orthopedic, Inc.Inventors: James F. Zucherman, Ken Y. Hsu, Charles J. Winslow, John J. Flynn, Steven T. Mitchell, Scott A. Yerby, John A. Markwart

Patent number: 8585738Abstract: An insert for establishing a desired spacing between a pair of succeeding vertebrae and having a body including an extending end for supporting a location associated with a first selected lumbar vertebrae. An opposite extending end supports a spaced apart and opposing location associated with a second successively positioned lumbar vertebrae. Upon pre-positioning the body in an open space established between the vertebrae, an actuating input causes the first extending end to displace outwardly relative to the second end and into contacting support with the vertebrae.Type: GrantFiled: May 14, 2012Date of Patent: November 19, 2013Inventor: Miguel A. Linares

Publication number: 20130304125Abstract: A system for surgically coupling the spinous processes includes a first plate, a second plate, a pair of semi-rigid guide members, and a coupler. The first plate engages with a first lateral side of the spinous processes. The pair of semi-rigid guide members attaches to the first plate for inserting the first plate between the spinous processes. The second plate includes a pair of apertures that slide over the pair of semi-rigid guide members engage a second lateral side of the spinous processes. The coupler couples the first plate and the second plate together.Type: ApplicationFiled: April 22, 2013Publication date: November 14, 2013Inventors: Jens Peter TIMM, Danielle RICHTERKESSING, Jared ARAMBULA

Patent number: 8568461Abstract: Medical devices and related methods for the treatment of spinal conditions are described herein. In one embodiment, a method includes disposing at least a portion of a support member into a space between adjacent spinous processes. The support member defines a lumen between a proximal end and a distal end of the support member. An expandable member is inserted through the lumen of the support member such that a distal end portion of the expandable member is disposed outside a distal end of the lumen and a proximal end portion of the expandable member is disposed outside a proximal end of the lumen. The distal end portion and the proximal end portion of the expandable member are then expanded such that each of the distal end portion and the proximal end portion of the expandable member has an outer diameter greater than an outer diameter of the support member.Type: GrantFiled: May 27, 2008Date of Patent: October 29, 2013Assignee: Warsaw Orothpedic, Inc.Inventor: Andrew C. Kohm
