An intervertebral fusion device comprising inferior and superior fusion cage devices that provide an ability to correct spondylolisthesis via in-situ adjustment.

A device for protecting a brassiere and other delicate undergarments during laundering includes a pair of domed or hemispherically shaped shells adapted to assemble together over a cup of the brassiere as a protective covering for the cup. The outer shell has a circularly shaped first rim portion and a hemispherically shaped first dome portion larger than the cup of the brassiere that extends to the first rim portion. The inner shell has a circularly shaped second rim portion and a hemispherically shaped second dome portion that extends to the second rim portion, said second dome portion having a size adapted to fit within the first dome portion of the outer shell with the first and second rim portions in concentric relationship and the cup of the brassiere disposed intermediate the first and second dome portions. At least three pins are included on the second rim portion of the inner shell and at least three pin-engaging structures are provided on the outer shell for engaging the pins in order to removably secure the inner shell to the outer shell with the cup of the brassiere in between. Each pin-engaging structure preferably defines a slot adapted to receive a pin in multiple pin positions with a friction fit sufficient to engage the pin. A further improved embodiment includes a circularly shaped cover member adapted to fit on the inner cage in order to form an auxiliary compartment for at least one additional clothing article.

An expandable intervertebral cage device includes a first base plate and a second base plate, a proximal block with internal threading that mechanically couples the first base plate and the second base plate, and a distal block comprising an internal passage. The device has exactly two arm assemblies, one on each side. Each arm assembly includes a first arm mechanically coupled to the first base plate and the distal block, and a second arm is mechanically coupled to the second base plate and the distal block. A screw is arranged partially within the internal threading of the proximal block and passes through the internal passage of the distal block, such that rotation of the screw relative to the proximal block causes a change in distance between the proximal block and the distal block, and a corresponding change in the spacing and lordosis of the device.

The invention relates to short steel strand stretching caging device and a method used for stretching and anchoring. The caging device consists of an arm brace, a supporting nut and a limited plate, wherein, the arm brace is a cylinder which is provided with two symmetrical windows and internal threads; the supporting nut which is positioned in the arm brace is a section of circular ring the central circumference of which is uniformly distributed with 1 to 8 through holes which are used for adjusting positions; external threads which are matched with the internal threads on the arm brace are arranged on the supporting nut which is connected with the arm brace through the external threads; the limited plate is a flat cylindrical plate the central part of which is uniformly provided with through holes used for steel strands to pass through and the end part of which is provided with a concave step; the number of the through holes on the limited plate is consistent with that of clamping piece holes on an archor plate of an archor component to be stretched; and the limited plate is positioned inside the arm brace and adjacent to the supporting nut. Under the condition of stretching, the arm brace of the stretching caging device is connected with a jack through bolts and the operations of primary stretching and secondary stretching can be realized by adjustment of the position of the supporting nut without replacement of the jack, thereby the structure of the device is simple and the construction method is convenient.
