Patent ID: 7588574

Claim:
A spinal fusion kit, comprising: an access tool, for providing access to a disc space; a tissue extraction tool, for removing disrupted material from the disc space; and a cutter assembly, for disrupting material in the disc space, the cutter assembly comprising: a shaft extending along a longitudinal axis between a shaft proximal end and, a shaft distal end; a handle extending proximate the shaft proximal end; and a blade comprising a flat ribbon member having a first end and a second end, the flat ribbon member having a first surface and a second surface extending between the first end and the second end, the first surface and the second surface joined by at least one cutter edge extending between the first end and the second end, the flat ribbon member forming a bend placing the first end the second end within proximity of each other, the bend exposing the first surface as an exterior surface of the blade and folding the second surface in toward itself as an interior surface of the blade, the blade actuatable between an extended configuration and a retracted configuration by the relative movement between the first end and the second end, wherein the extended configuration comprises the bend extending radially outwardly at approximately a 90 degree angle from the longitudinal axis of the shaft, wherein the retracted configuration comprises the bend extending axially distally roughly parallel to the longitudinal axis of the shaft.
