20080208258 | Methods and instruments for endoscopic interbody surgical techniques - This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. A cannula is inserted to create a working channel through the skin and tissue of a patient using a transformational approach to the disc space. A viewing element is used to visualize working end of the cannula and the disc space. A facetectomy is performed through the working channel to access the disc space. The disc space is prepared with various instruments, such as distractors, shims, chisels and distractor-cutters that extend through the working channel. At least implant is inserted into the disc space. The procedure allows bi-lateral support of the adjacent vertebrae with the at least one implant inserted via a unitary, minimally invasive approach to disc space. | 08-28-2008 |
20090105836 | Devices and techniques for a posterior lateral disc space approach - This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach. | 04-23-2009 |
20090270871 | Impulsive percussion instruments for endplate preparation - A hand-held instrument, with a rotary power input to a camshaft, has cam and follower arrangement to provide a reciprocating shaft output. A cutter is provided on the output shaft. In one example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pushing the instrument forward toward the cutter. In another example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pulling the instrument back toward the user while maintaining engagement of the cutter with the tissue. In both examples, the cutter remains in idle condition until an axially directed load, forward in the one example, or backward on the other example, is placed on the cutter by moving the instrument forward or backward, respectively, while the camshaft is rotating. A distractor with frame is used to spread and maintain space between vertebral bodies, enabling entrance of the cutter. | 10-29-2009 |
20100063554 | Interbody fusion grafts and instrumentation - This invention relates to implants formed from donor bone for use in lumbar interbody fusion procedures and instruments for performing such procedures. The implants are formed to include a concave surface formed from a portion of the medullary canal of a long bone. The concave surface defines a recess in the implant that serves as a depot for osteogenic material. Specific instruments for inserting the implants prepared according to this invention and for preparing the intervertebral space to receive the implants are also provided. | 03-11-2010 |
20100331845 | Methods and instruments for interbody surgical techniques - This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. The instruments include a distractor and a cutting instrument. In one embodiment the distractor includes a body portion and a pair of flanges extending along opposite sides of the body portion such that a slot is formed between the flanges and the body portion. The cutting instrument is positionable over the body portion and into the slots of the distractor so that the flanges are positioned between the cutting instrument and the adjacent tissue. | 12-30-2010 |
20130030535 | METHODS AND INSTRUMENTS FOR ENDOSCOPIC INTERBODY SURGICAL TECHNIQUES - This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. A cannula is inserted to create a working channel through the skin and tissue of a patient using a transforaminal approach to the disc space. A viewing element is used to visualize working end of the cannula and the disc space. A facetectomy is performed through the working channel to access the disc space. The disc space is prepared with various instruments, such as distractors, shims, chisels and distractor-cutters that extend through the working channel. At least implant is inserted into the disc space. The procedure allows bi-lateral support of the adjacent vertebrae with the at least one implant inserted via a unitary, minimally invasive approach to disc space. | 01-31-2013 |

20100228294 | ANTERIOR PLATING SYSTEM AND METHOD - Systems and methods for stabilizing the spine are provided. For stabilizing the L5-S1 junction, the system includes a plate that has a generally triangular shape with an upper node and a pair of lower nodes. The upper node has a hole through the plate to receive a screw for passage into the L5 vertebra. The lower nodes each include a hole through the plate to receive screws for passage into the S1 vertebra. The system further includes a plate having a retaining element for preventing backout of screws inserted through the plate. Instruments and methods for attaching the plate to the spinal column are also provided. | 09-09-2010 |

20120191144 | INSTRUMENT FOR REDUCTION OF A VERTEBRAL ROD AND METHOD OF USE - An instrument and method for reducing a vertebral rod into an anchor attached to a vertebral member. The instrument may include a gripper configured to attach to an anchor, an elongated shaft extending along a longitudinal axis between opposing jaws of the gripper, and a reducing element disposed at least partially outside the first and second jaws of the gripper and configured to engage with the vertebral rod. A release device may also be disposed about the elongated shaft and may be movable relative thereto such that the release device may be selectively engaged with a threaded outer surface of the elongated shaft. The reducing element may therefore be alternatively slidable relative to the gripper or threadably movable relative to the gripper by interaction with the elongated shaft, depending on a position of the release device. | 07-26-2012 |
