Abstract: A spacer separates bones of a joint using a driver tool having a threaded shaft. The spacer has a superior endplate with inferior facing ramps, and an inferior endplate with superior facing ramps. Two bearings are positioned between the endplates, each bearing has superior facing ramps which mate with the inferior facing ramps of the superior endplate, and inferior facing ramps which mate with the superior facing ramps of the inferior endplate. One bearing has a threaded aperture, and the other a thrust surface. A threaded shaft is threaded into the threaded aperture to push against the thrust surface to drive the bearings apart. As the bearings move apart, the mated ramps slide against each other to drive the superior and inferior endplates apart.

Abstract: Apparatus and associated methods relate to a balloon kyphoplasty surgical device comprising an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement. An exemplary implementation may be configured with multiple inner balloons housed in an outer balloon to create a specific shape. Some designs may be configured with multiple ports designed to individually and independently inflate each inner balloon and outer balloon. The outer balloon may be inflatable. The outer balloon may be sealed off, constraining inflation of the inner balloons to create a cubic-like shape when the inner balloons are inflated within the sealed outer balloon, resulting in improved vertebral structure stabilization by increased surface area lifting the bone.
