Patent ID: 7507241

Claim:
An expandable bone device comprising: a unitary body extending along a longitudinal axis and including a deformable distal end portion having a collapsed orientation for placement adjacent a bone structure, said deformable distal end portion comprising relatively wide, mutually contiguous support surfaces outlined by relatively narrow cutouts, said support surfaces being contiguous with the rest of the unitary body via relatively narrow deformable splines, said deformable distal end portion having an expanded orientation wherein said support surfaces are moved transversely outwards away from and generally parallel to the longitudinal axis, and wherein in the expanded orientation, distal ends of said support surfaces are disconnected and distanced from one another by an open gap; and an actuator coupled to said deformable distal end portion and operative to cause movement of said deformable distal end portion between the collapsed orientation and the expanded orientation and wherein in the expanded orientation said deformable splines are misshapen as compared to the collapsed orientation.
