Abstract
Devices and methods for performing a procedure within a spine are disclosed herein. In one embodiment, a method includes expanding an expandable member to move a tissue portion and form a cavity within an interior of a bone-related structure. At least a portion of the cavity is filled with a filler material while simultaneously withdrawing a medium from the expandable member at a predefined ratio such that the tissue portion substantially maintains its moved position. In some embodiments, the predefined ratio is 1:1. In another embodiment, a method includes expanding an expandable member to move a tissue portion and form a cavity within an interior of an intervertebral disc. At least a portion of the cavity is filled with a filler material while substantially maintaining the moved position of the tissue portion.
