The extension members may vary in size and shape so that the most appropriate extension member can be chosen to address the intrusion problem, and the extension members may be mounted at various fixed locations, using clips, mechanical interlocking structures or the like. | 05-06-2010 |
20110112586 | METHODS AND DEVICES FOR PORTAL FIXATION TO THE SPINE - A method and device for attaching a curvilinear access device having a movable top and an expandable working portal to the spine, the attachment including a holding arm assembly, posterior tang, anterior tang and/or a portal fixation pin. | 05-12-2011 |
20110144652 | System, instrumentation and method for spinal fixation using minimally invasive surgical techiques - A pedicle screw tower having a guide chute, open at both ends, affixed to the exterior of the main body of the tower. The guide chute extends the length of the tower and is curved inwardly at its bottom such that the exit direction is at approximately 90 degrees to and facing the central axis of tower. A guide cable is passed into and through the guide chute such that it is directed across the tower to an adjacent tower. | 06-16-2011 |
20110184473 | Method and apparatus for spinal fixation using minimally invasive surgical techniques - An improved method and guide wire assembly used in a system, set of instrumentation and method comprising the combination and use of plural pedicle screws, a rod for connecting pedicle screws in a relatively rigid manner, and instrumentation to optimize insertion of the rod into the pedicle screws, the assembly having a guide wire and instrumentation to grasp a medial portion of the guide wire to pull the medial portion through all the pedicle screws and connecting the loop to the end of a fixation rod, whereby one end of the guide wire is mounted to a pedicle screw, all the screws are implanted into the vertebrae, and the rod subsequently guided into the pedicle screws by pulling the guide wire loop back through the pedicle screws, all using minimally invasive surgical incisions. | 07-28-2011 |

20130178862 | Intervertebral Implant Insertion Device and Method - An implant insertion device and its method of use, the device having a pair of opposing elongated blades retained by a housing. The distal ends of the blades are adapted to be inserted into the vertebral interspace. The housing comprises an internally threaded bore. An insertion rod having an elongated threaded rod passes through the housing and between the blades, whereby rotation of the insertion rod relative to the housing causes it to advance within the housing. An implant is temporarily mounted to the end of the insertion rod. As the insertion rod is advanced, the implant forces the distal ends of the blades apart such that proper placement of the implant in the intervertebral space is readily achieved. Once the implant is properly positioned free of the blades, the device is removed. | 07-11-2013 |
