    • An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.
    • 提供了一种椎间支架系统,其具有可用于从扩张状态到塌陷状态的可逆塌陷的后向张开的框架,具有稳定器的后向张开框架,一个或多个张紧器或者 稳定器与一个或多个张紧器的组合。 稳定器可滑动地接合后加力扩张框架的远侧区域,并且稳定器和一个或多个张紧器两者被构造成用于将横向运动保持在向后扩张的框架上,该横向运动超过扩张状态,并且稳定器可包括锁定 当膨胀构件完全插入框架中时,膨胀构件与膨胀构件接合以将膨胀构件锁定到稳定器。 例如,扩张状态可以被配置成具有开放的移植物分布窗口,该窗口在可逆塌陷时至少基本闭合。
