    摘要: A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone) against the inner cortex of bones whether the bones are fractured or not. The balloon comprises an inflatable, non-expandable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon is prevented from applying excessive pressure to the outer cortical bone. The wall or walls of the balloon are such that proper inflation the balloon body is achieved to provide for optimum compression of all the bone marrow. The balloon is able to be folded so that it can be inserted quickly into a bone. The balloon can be made to have a suction catheter. The main purpose of the balloon is the forming or enlarging of a cavity or passage in a bone, especially in, but not limited to, vertebral bodies.

    摘要: An elongated shaft is sized and configured to establish an access path to bone having an interior volume occupied, at least in part, by cancellous bone. The elongated shaft includes a generally closed distal end portion and a side opening spaced from the closed distal end. A first tool is sized and configured to be selectively inserted into the shaft and selectively removed from the shaft. The tool includes a region that, when the first tool is inserted into the shaft, is capable of being aligned with and advanced through the side opening to project outside the side opening and contact cancellous bone. A second tool is sized and configured, upon removal of the first tool from the shaft, to introduce into the shaft a bone filling material for discharge through the side opening into the cancellous bone contacted by the first tool.

    摘要: The invention discloses an implantable facet arthroplasty device suitable for treating adjacent level disease. The device is designed for implantation between a first vertebra and a second vertebra. Components of the device include: a crossbar; a first component having a first attachment mechanism adapted to attach to a first location of a spinal fusion device attached to a first vertebra and a second attachment mechanism adapted to attach to the crossbar; and a second component having a second attachment mechanism adapted to attach to a second location of a spinal fusion device attached to the first vertebra and a second attachment mechanism adapted to attach to the crossbar. The first component articulates relative to the second component and the first vertebra articulates relative to the device itself.
