Patent attributes
A bellows shaped spinal implant, comprising an upper plate having an upper opening therethrough, a lower plate having a lower opening therethrough, and aa bellows shaped shell extending between and joining the upper plate and the lower plate. The bellows shaped shell is formed of titanium or an alloy comprising titanium and includes a wall extending continuously therearound that defines a hollow interior in communication with the upper opening and the lower opening. The wall has a thickness in the range of 0.5 mm to 1.0 mm to provide for radiographic imaging through the wall. The wall is angled or curved inwardly or outwardly between the upper plate and the lower plate to provide stiffness that mimics the stiffness properties of a similarly sized polyetheretherketone (PEEK) implant.
