    infusing a first fluid into the expandable body to expand the expandable body so that a desired amount of distraction is achieved at the distraction gap;

    removing the first fluid from the expandable body;

    determining an amount of the first fluid removed from the expandable body;

    infusing an amount of a light-sensitive liquid through the open end into an open inner cavity of the expandable body that adjustably changes the distraction thickness of the expandable body without changing the insertion depth or width of the expandable body, wherein the amount of light-sensitive liquid is substantially equivalent to the amount of the first fluid;
