    Abstract: An inelastic expandable device has an expanded configuration and an unexpanded configuration. The inelastic expandable device is sized and configured for introduction into a cancellous bone volume of a vertebral body through a percutaneous access path while in the unexpanded condition and for expansion while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration. The inelastic expandable device is sized and configured for controlling the expansion so that the expandable device expands more in an inferior-to-superior direction than in a lateral direction.

    Abstract translation: 非弹性可扩展装置具有扩展配置和未扩展配置。 该非弹性可扩张装置的尺寸和构造适于在处于未膨胀状态下通过经皮进入路径引入椎体的松质骨体积中,并且用于在松散骨体积内从未膨胀构型向扩张构型放置时扩张。 非弹性可膨胀装置的尺寸和构造用于控制膨胀,使得可膨胀装置在向下方向上比沿横向方向更向下扩展。
