    摘要： An expandable device includes an expanded configuration and an unexpanded configuration. The expandable device is sized and configured for introduction into the cancellous bone volume of the vertebral body through the percutaneous access path while in the unexpanded condition. The expandable device is also sized and configured for expansion while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration, to create a cavity. The expandable device includes material 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, so that the cavity that is created occupies less than the cancellous bone volume.

    摘要翻译： 可扩展设备包括扩展配置和未扩展配置。 可扩张装置的尺寸和构造适于在未膨胀状态下通过经皮进入路径引入椎体的松质骨体积。 可扩张装置的尺寸和构造也用于在从松散构型向膨胀构型放置在松质骨容积内的同时进行扩张，以产生空腔。 可扩张装置包括尺寸和构造用于控制膨胀的材料，使得可膨胀装置在向下方向上比在横向方向上更多地膨胀，使得所产生的空腔占据松质骨体积。

    摘要： A vertebral body is selected for treatment. The vertebral body has a cortical wall enclosing a cancellous bone volume. The vertebral body has at least one cortical plate that is depressed due to fracture. At least one maximum dimension for the cancellous bone volume is ascertained. An expandable device is provided having an expanded configuration and an unexpanded configuration. The expandable device has a predefined dimension when substantially expanded that is less than the maximum dimension. The expandable device is introduced into the vertebral body through a percutaneous access path while in the unexpanded condition. The expandable device is expanded while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration to create a cavity that occupies less than the cancellous bone volume.
