Abstract

An expandable spinal implant including at least two expandable branch portions extending generally along a longitudinal axis and each including a fixed end portion and an opposite movable end portion with the fixed end portions coupled together adjacent a base portion of the implant. A first of the branch portions includes at least one transverse projection having opposite axially-facing outer surfaces. A second of the branch portions defines at least one transverse recess having opposing axially-facing inner surfaces. The transverse projection is positioned within and displacable along the transverse recess with the outer surfaces of the projection positioned in close proximity with the inner surfaces of the recess to provide structural support to the implant subsequent to expansion. In one embodiment, the branch portions are separated from one another by at least one slot including a narrow portion that defines the close fitting transverse projection and transverse recess.
