  • Patent number: 11185420
    Abstract: An expandable cage which is used in spinal surgery and which allows adjustment of distance between two vertebrae in which it is placed as preferred. An expandable cage-basically includes at least one body which is located in emptied area between damaged vertebrae during the surgical procedure and serves as a disc; and at least one movable element which is located on the body and is fitted in the opening made in the body by means of the retainers disposed at the sides thereof; which has a toothed surface contacting with the upper vertebra and being attached to it; and the height of which can be adjusted by pushing the protrusion provided in the lower portion thereof according to the intervertebral distance of patient by means of the expansion apparatus.

  • Patent number: 10350082
    Abstract: An expandable cage which is placed between the vertebrae, is moveable when preferred, closes the opening between the vertebrae upon being moved, and hence can be integrated in any intervertebral opening. The expandable cage has at least one body with at least one space and at least one rib; at least one moveable part which is located inside the body and has at least one bearing area, at least one base, and at least one nail, the moveable part being moved unilaterally by the balloon; at least one balloon which applies the force required to be applied on the base of the moveable part for ensuring unilateral movement of the moveable part; at least one hole through which the balloon can pass; and at least one compression element which supplies the required fluid to the balloon.

  • Publication number: 20180296357
    Abstract: An expandable cage is placed between two vertebrae and expandable at a preferred ratio towards the vertebrae (i.e. in longitudinal axis). The expandable cage has at least one protrusion which is provided in the body and which, in case of a force being applied, forms a pointed tip out of the body, and at least one balloon which applies the required force to the protrusion such that the protrusion will move unilaterally.
