20090043340 | IMPLANTABLE BONE PLATE SYSTEM AND RELATED METHOD FOR SPINAL REPAIR - A system for performing surgical repair of the spine includes a distractor and a permanently implanted bone plate system. A surgical repair methodology is also disclosed that employs an implanted bone plate system with a substantially void internal volume which is attached to adjacent vertebrae subsequent to the distraction and adjustment of curvature of said vertebrae and prior to the excision of end plate tissue there-through. The device further facilitates the subsequent delivery of an interbody repair device for the purpose of either fusion or dynamic stabilization, such as by disc arthroplasty. The plate may be permanently implanted, such as when a fusion between the attached vertebral bodies is desired, but it need not be permanently implanted | 02-12-2009 |
20090076516 | DEVICE AND METHOD FOR TISSUE RETRACTION IN SPINAL SURGERY - The invention relates to a system and methods for retracting soft tissue during spinal repair or reconstruction procedures, particularly procedures within intervertebral sites of degenerated discs and associated neural compression. A retractor system includes an implantable bone plate, two or more retractor blades, the bone plate and retractor blades being mutually engageable; and a mechanism to adjust the retractor blade relative to the bone plate. In some embodiments, the retractor system may be applied to span more than one intervertebral space. An implanted retractor system provides an aperture for a clear operating field, and protects collateral tissue. A method for retracting soft tissue to facilitate spinal surgery includes securing a bone plate to adjacent vertebral bodies, engaging one or more retractor blades to the bone plate; and adjusting the angular position of the retractor blade relative to the bone plate so as to retract tissue lying external to the bone plate. | 03-19-2009 |
20090076555 | TRANSCORPOREAL SPINAL DECOMPRESSION AND REPAIR SYSTEM AND RELATED METHOD - A system and method are provided for making an access channel through a vertebral body to access a site of neural compression, decompressing it, and repairing the channel to restore vertebral integrity. System elements include an implantable vertebral plate, a guidance device for orienting bone cutting tools and controlling the path of a cutting tool, a bone cutting tool to make a channel in the vertebral body, a tool for opening or partially-resecting the posterior longitudinal ligament of the spine, a tool for retrieving a herniated disc, an implantable device with osteogenic material to fill the access channel, and a retention device that lockably-engages the bone plate to retain it in position after insertion. System elements may be included in a surgery to decompress an individual nerve root, the spinal cord, or the cauda equina when compressed, for example, by any of a herniated disc, an osteophyte, a thickened ligament arising from degenerative changes within the spine, a hematoma, or a tumor. | 03-19-2009 |
20090088604 | VERTEBRALLY-MOUNTED TISSUE RETRACTOR AND METHOD FOR USE IN SPINAL SURGERY - A retractor system and associated method are provided to manage soft tissue around a spinal surgical field. The system includes a hollow retractor with proximal and a distal apertures and an internal circumferential surface connecting the apertures, the surface and the apertures defining an operating volume and the area of the distal aperture defining an operating field. The system may further include other elements such as a handling tool to facilitate placement and removal of the retractor, a bone cutting tool, a trajectory control sleeve to guide the bone cutting tool, and/or an implantable bone plate upon which to position the retractor. A method for spinal surgery, particular from an anterior approach, includes positioning the retractor at a surgical site, and performing a medical procedure through the operating volume provided by the retractor. | 04-02-2009 |
20090099568 | DEVICE AND METHOD FOR VARIABLY ADJUSTING INTERVERTEBRAL DISTRACTION AND LORDOSIS - A removably insertable surgical apparatus is configured for insertion between adjacent vertebrae during spinal surgery and adjusted in-situ to produce varying degrees of distraction, neural-decompression, lordotic, kyphotic and/or scoliotic adjustment in the spine. | 04-16-2009 |
20090143716 | METHODS AND SYSTEMS FOR REPAIRING AN INTERVERTEBRAL DISC USING A TRANSCORPORAL APPROACH - The invention includes a system and methods for performing surgery on a spinal disc. The system includes an implantable bone plate with an access port to accommodate a bone cutting device, a spinal repair device insertable through the access port of the bone plate configured to occupy a surgically-formed vertebral channel from an anterior surface of the host vertebral body to a site central to an end plate of the host vertebral body, a trajectory control sleeve engageable to the bone plate to direct the trajectory of a cutting device, and a cutting device engageable within the trajectory control sleeve. Methods are directed to forming a vertebral channel and restoring the vertebral body and disc with devices that both repair the bone and the disc. | 06-04-2009 |
20100057134 | IMPLANTABLE BONE PLATE SYSTEM AND RELATED METHOD FOR SPINAL REPAIR - A system for performing surgical repair of the spine includes a distractor and a permanently implanted bone plate system.
