| 20090326585 | VERTEBRAL FIXING SYSTEM - The invention relates to a vertebral fixing system suitable for being mounted on a vertebra of the spine for connecting it to a rod ( | 12-31-2009 |
| 20100121387 | SURGICAL TOOL FOR TENSIONING A FLEXIBLE MEMBER - A surgical tool for tensioning a flexible member of a vertebral device, the flexible member having at least one end portion to which tension is applied. The surgical tool includes a longitudinal member having a longitudinal axis, a first end provided with an element for securing in rotation at least one end portion of the flexible member with the first end of the longitudinal member, and a second end provided with a handling element. The surgical tool also includes a guiding structure comprising a first end adapted to be applied against the body of the vertebral device, and at least one guiding element for guiding in rotation the longitudinal member about the longitudinal axis. The guiding structure maintains the longitudinal axis of the longitudinal member with respect to the body, whereby the rotation of the longitudinal member with the handling element produces the tensioning of the flexible member. | 05-13-2010 |

| 20090105715 | BONE FIXATION TENSIONING TOOL AND METHOD - A tensioning tool and method for tensioning a conformable ligature of a bone fixing system are disclosed. The ends of a conformable ligature can be passed around bones, bone grafts, tendons, plates, rods, fasteners, or other anatomical or implanted structures, and the like to form a loop. Another portion of the conformable ligature can be coupled to a tensioning tool. The tensioning tool can include a first portion and a second portion in threaded engagement with each other. Rotation of one portion relative to the other can cause tensioning of the conformable ligature through translation of a tensioning member. | 04-23-2009 |
| 20090292317 | SYSTEM FOR STABILIZING AT LEAST TWO VERTEBRAE - This disclosure provides a spinal stabilization system and method for stabilizing at least two vertebrae. The system holds together the vertebrae while allowing a limited amount of relative movement between the vertebrae. The system may include a flexible braid having two free ends, at least one spacer interposed between the spinous processes of the vertebrae, and a securing mechanism for securing the two ends of the braid to hold the at least one spacer between the spinous processes of the vertebrae. In some embodiments, the securing mechanism may comprise parts movable relative to each other. Portions of the braid may be placed between the movable parts. A mechanical member may cause the movable parts to move towards each other to secure the two ends of the braid. | 11-26-2009 |
