20100082106 | VERTEBRAL BODY REPLACEMENT - This invention concerns a vertebral body replacement element to be inserted into an intervertebral space, thus supporting the spinal column of a patient. The vertebral body replacement element has a hollow upper member and a hollow lower member, with the upper member and lower member engaging in a telescopic manner and establishing a cavity between the two members when assembled. Spacers may be inserted in the cavity to lengthen the vertebral body replacement element. The present invention further concerns a system and method for expanding and distracting a vertebral body replacement element into and within the spinal column of a patient. | 04-01-2010 |
20100211107 | FACET JOINT PROSTHETIC REPLACEMENT AND METHOD - The present disclosure provides prosthesis, methods, and kits for replacing a facet joint, in particular prosthesis, methods, and kits for replacing a spinal motion segment comprising a facet joint. The prosthesis includes a first and second member that interlock to form a sliding joint. | 08-19-2010 |
20110040382 | POSTERIOR SPINAL IMPLANT SYSTEM - Disclosed is a spinal implant comprising an implant spacer body and a plate. The spinal implant may be installed into an inter-vertebral space between adjacent vertebrae and may be installed from a patient's posterior. The implant spacer body tapers from the anterior toward the posterior and may be tapered at the anterior end to facilitate installation. Some embodiments disclosed herein may comprise an implant spacer body only, some embodiments may comprise a plate only, and some embodiments may comprise an implant spacer body and a plate. | 02-17-2011 |
20110071637 | SYSTEM AND METHODS FOR INSERTING A VERTEBRAL SPACER - The present invention provides vertebral spacers having a lower surface and an upper surface, an anterior face and a posterior face extending from the lower surface, and at least one guiding groove for engaging an insertion tool. A system for delivering a vertebral spacer to the spinal column of a patient, includes an insertion tool, an optional guiding tool, a pusher, a vertebral spacer, and a cutting tool. The insertion tool accepts any of a pusher, a vertebral spacer, or a cutting tool and has at least one spacer guide for engaging with a guiding groove of a vertebral spacer. The vertebral spacer is inserted into a patient by inserting the insertion tool into an intervertebral space, engaging the guiding groove of a vertebral spacer with a space guide of the insertion tool, advancing a pusher into the insertion tool, thereby pushing the vertebral spacer into the intervertebral space and thereafter removing the pusher and the insertion tool. The cutting tool is optionally used to chisel at least one vertebral space receiving slot in the vertebrae. A hardening biocompatible composition also maybe delivered, to bond the vertebral spacer to an adjacent vertebra or be an osteogenic composition to promote bone growth. | 03-24-2011 |
20120046751 | VERTEBRAL BODY REPLACEMENT AND METHOD OF USE - Vertebral body replacements are provided, including at least one vertebral body replacement in the shape of an oblong object. The oblong vertebral body replacement includes a nose shape to provide as minimally invasive an installation as possible, serrations formed in the side wall of the body replacement's body to prevent expulsion once the body replacement is in place, a tapered asymmetric shape to provide spinal lordosis, and an integral protrusion for stability and to increase the bearing area to reduce contact pressure between the body replacement and the vertebral plate. Hollow passages are typically filled with bone tissue. The body is also provided with holes passing therethrough to promote tissue growth. | 02-23-2012 |
20140277495 | POSTERIOR SPINAL IMPLANT SYSTEM - Disclosed is a spinal implant comprising an implant spacer body and a plate. The spinal implant may be installed into an inter-vertebral space between adjacent vertebrae and may be installed from a patient's posterior. The implant spacer body tapers from the anterior toward the posterior and may be tapered at the anterior end to facilitate installation. Some embodiments disclosed herein may comprise an implant spacer body only, some embodiments may comprise a plate only, and some embodiments may comprise an implant spacer body and a plate. | 09-18-2014 |
