20090312837 | EXPANDABLE INTERVERTEBRAL IMPLANT - An expandable intervertebral implant including a body having a longitudinal axis and including first and second axial walls spaced apart along a transverse axis, and first and second transverse end walls extending between and interconnecting the first and second axial walls. The intervertebral implant includes an expansion member co-acting with the axial walls to expand the body along the transverse axis. | 12-17-2009 |
20100324684 | Spinal Prosthetic Joints - A method for correcting spondylolisthesis from the lateral approach is provided in which a pair of insertion members are inserted laterally into upper and lower vertebrae, a connecting member is affixed to the insertion members, and a rotating force is applied to the connecting member to encourage the upper and lower vertebrae into a desired position relative to one another. | 12-23-2010 |
20110098819 | Spinal Disc Prosthesis and Associated Methods - A prosthetic device for insertion into a spondylosed intervertebral space is provided. The prosthetic device includes a first component having a first flange for longitudinally engaging a first vertebra during longitudinal insertion therein, and a second component having a second flange for longitudinally engaging a second vertebra during longitudinal insertion therein. One of the first and second components comprises a projection and the other of the first and second components comprises a recess, the projection and recess being adapted to engage one another. One of the projection and the recess are offset relative to the other of the projection and the recess to accommodate the spondylosed relationship between the first and second vertebrae. | 04-28-2011 |
20110106263 | Spinal Disc Prosthesis and Associated Methods - A prosthetic device for insertion into a spondylosed intervertebral space is provided. The prosthetic device includes a first component having a first flange for longitudinally engaging a first vertebra during longitudinal insertion therein, and a second component having a second flange for longitudinally engaging a second vertebra during longitudinal insertion therein. One of the first and second components comprises a projection and the other of the first and second components comprises a recess, the projection and recess being adapted to engage one another. One of the projection and the recess are offset relative to the other of the projection and the recess to accommodate the spondylosed relationship between the first and second vertebrae. | 05-05-2011 |

20090222011 | Targeting surgical instrument for use in spinal disc replacement and methods for use in spinal disc replacement - A targeting surgical instrument for use in spinal disc replacement includes a first arm, a second arm and a body portion. The first arm is configured to be longitudinally aligned with a mid-line of a spine and to be at least partially received on an endplate of a lower vertebra of spinal cavity. The spinal cavity is defined by a lower vertebra and an upper vertebra of the spinal cavity. The second arm is positioned at an angle relative to the first arm. The second arm defines an insertion angle for a spinal implant. The body portion connects the first arm and the second arm. The body portion includes a plurality of radial opaque markers located to allow alignment of the first arm on the mid-line of the spine. | 09-03-2009 |
20100286778 | Textile-Based Spinal Implant and Related Methods - A textile-based surgical implant that can be inserted through any number of suitable surgical approaches, including but not limited to lateral, anterior, anterior-lateral, posterolateral, and/or posterior approaches. When applied to spine surgery and inserted into an intervertebral disc space, the implant restores the normal height of the intervertebral disc space, while advantageously preserving the natural motion of the spine. The textile construction of the implant is beneficial because it is generally compliant and thereby restores and/or improves spinal motion. The compliant nature of the textile-based implant provides the required flexibility and elasticity to advantageously support physiological movements, as opposed to fusion surgery which forms a boney bridge between adjacent vertebral bodies. In addition, the porosity and biocompatibility of the textile-based implant facilitates tissue ingrowth throughout part or all of the implant, which helps to secure and encapsulate the implant in the intervertebral space. | 11-11-2010 |
20110060366 | Facet Joint Implant and Related Methods - Implants and methods aimed at safely repairing and/or reconstructing the facet joint so as to provide the required flexibility and elasticity to support continued motion after the implant has been implanted in a facet joint. | 03-10-2011 |
20120303072 | BONE SCREW SYSTEM WITH CONNECTING PORTION - A bone screw system includes a bone screw and a connecting device for coupling the bone screw to an elongate rod-shaped member. The bone screw has proximal and bone-engaging portions disposed at opposing ends relative to a long axis of the screw. The proximal portion includes a proximal locking feature that extends away from the long axis in a radial direction that is perpendicular to the long axis. The connecting device includes first and second coupling portions at opposing ends relative to the long axis when the coupling device is assembled to the bone screw. The first coupling portion defines an opening for receiving the proximal portion of the bone screw. The second coupling portion is configured to receive the rod-shaped member. The connecting device also includes a restraining feature that frictionally resists rotational motion of the connecting device relative to the bone screw. | 11-29-2012 |
20130060288 | METHODS AND INSTRUMENTATION FOR ORTHOPEDIC SURGERY - Surgical instruments and methods aimed at the proper placement and installation of textile-based orthopedic implants. More specifically, the surgical instruments include a flexible template, insertion instrument and multi-pronged awl. The flexible template may be formed of a combination of rigid and flexible materials and is deformable to match the contour of the target anatomy for subsequent placement of a textile-based orthopedic implant. The insertion instrument has a handle and a template end used for holding the flexible template and textile-based implant. The template end has one or apertures with hollow cylindrical extensions for holding the flexible template or textile-based implant and one or more cutout regions for better visualization and affixation of fixation screws. An awl is also provided with one or more prongs to initiate channels for the fixation screws. A method of implanting a textile-based orthopedic implant is also disclosed. | 03-07-2013 |
