Latest Patents

Keeney is credited with 1 patent: “Expandable Interbody Fusion Device for Use with Posterior to Lateral Approach.” The invention describes a disc implant formed from a generally planar rectangular sheet with alternating joint-ridge and arm-ridge segments. The joint segments provide flexibility, while the arm segments form radially extending arms. When the sheet is folded or rolled into a generally cylindrical shape, the arms can collapse axially and expand radially, with spacing joint segments between the expanded arm sections.

Career Highlights

The patent highlights Keeney’s contribution to implant design for interbody fusion procedures. Its structure is intended to combine flexibility during shaping with radial expansion in its cylindrical configuration.
