    • One embodiment of a spinal fixation system 10 including a pair of longitudinal members 11, 12 positionable adjacent the spine, means for engaging longitudinal members to the spine 13, 14, a pair of wedge members 16 each having a bearing surface 38 configured to bear on a longitudinal member 11, 12, and a connector 20 configured to span a distance between the longitudinal members 11, 12. The connector 20 includes a pair of engaging members 25, 26 each having a fixation surface 33 and a connecting surface 30, and a bridge member 21 attached to the connecting surfaces 30. The engaging members 25, 26 each define a thru-hole 35 for receiving one of the wedge members 16. The thru-holes 35 are aligned so that wherein one of the wedge members 16 is advanced through the thru-hole 35, the bearing surface 38 will bear on a corresponding longitudinal member 11, 12 to force the longitudinal member 11, 12 into contact with the fixation surface 33 and engage the longitudinal member 11, 12 to the connector 20.

    • A device for stabilizing at least a portion of the spinal column, including a longitudinal member sized to span a distance between at least two vertebral bodies and being at least partially formed of a shape-memory material exhibiting pseudoelastic characteristics at about human body temperature. A number of bone anchors are used to secure the longitudinal member to each of the vertebral bodies. The longitudinal member is reformed from an initial configuration to a different configuration in response to the imposition of stress caused by relative displacement between the vertebral bodies, and recovers toward the initial configuration when the stress is removed to thereby provide flexible stabilization to the spinal column. During reformation of the longitudinal member, at least a portion of the shape-memory material transforms into stress-induced martensite. In a particular aspect of the invention, the longitudinal member is a plate having a central portion at least partially formed of the shape-memory material, and a pair of connection portions disposed at opposite ends of the central portion for connection to each of the vertebral bodies. The central portion of the plate defines a number of alternating ridges and grooves along a length thereof having an initial amplitude corresponding to the initial configuration and a different amplitude corresponding to the different configuration.
    • 一种用于稳定脊柱的至少一部分的装置,包括纵向构件,所述纵向构件的尺寸设置为跨越至少两个椎体之间的距离,并且至少部分地由在大约人体温度下显示假弹性特征的形状记忆材料形成。 使用许多骨锚来将纵向构件固定到每个椎体。 响应于施加由椎体之间的相对位移引起的应力而将纵向构件从初始构型重新形成为不同的构造,并且当应力被移除时朝向初始构型恢复,从而向脊柱提供柔性稳定性。 在纵向构件的改造期间,形状记忆材料的至少一部分转变为应力诱导马氏体。 在本发明的特定方面中,纵向构件是具有至少部分地由形状记忆材料形成的中心部分的板,以及设置在中心部分的相对端部处的一对连接部分,用于连接到每个脊椎 身体。 板的中心部分沿着其长度限定了多个交替的脊和槽,其具有对应于初始构型的初始幅度和对应于不同配置的不同幅度。
