Abstract: A method of positioning an arcuate tool against inner annular walls of the disc that particularly facilitates reaching posterior and postero-lateral portions of the inner annulus of the disc by arthroscopy. An elongated, arcuate and shape memory tool such as a catheter is positioned against the inner annular wall of the disc, and particularly on the posterior and postero-lateral portions of the inner annulus of the disc, which are portions of the disc to be treated. The deformable and arcuate tool retains its predetermined arcuate shape when no pressure or force is applied to the tool.

Abstract: A method of positioning an S-shaped tool against inner annular walls of the disc that particularly facilitates reaching posterior and postero-lateral portions of the inner annulus of the disc by arthroscopy. An elongated, arcuate and S-shaped tool such as a catheter is positioned against the inner annular wall of the disc, and particularly on the posterior and postero-lateral portions of the inner annulus of the disc, which are portions of the disc to be treated. The deformable, arcuate and S-shaped tool retains its predetermined arcuate, S-shape when no pressure or force is applied to the tool.

Abstract: A method of positioning an arcuate device against the inner walls of the disc, and particularly on the posterior and postero-lateral portions of the inner annulus of the disc. The arcuate device retains its predetermined arcuate shape when no pressure or force is applied to the catheter. In an embodiment, an arcuate cutter is used to remove tissue from the inner annulus of the disc. In another embodiment an arcuate device is used to progressively remove material from the interior of the mammalian intervertebral disc. In yet another embodiment, an arcuate device is used to remove the entire intervertebral disc and place supports to maintain a disc space.

Abstract: A device and method for removing tissue, and if required, other undesired materials from an intervertebral disc or vertebral body. An elongated arcuate, and preferably S-shaped tool is used to progressively remove material from the interior of the mammalian intervertebral disc or vertebral body. A sheath introduces the elongated tool by a posterior, postero-lateral or lateral approach. The shape of the elongated tool is formed within a guide or lumen of the sheath for transportation through the sheath. The elongated tool assumes its predetermined arcuate shape when no pressure or force is applied to the tool by the sheath as the elongated tool exits the sheath. The device and method allow positioning of new material in the intervertebral disc and/or vertebral body. The new material may be tissue, therapeutic agents, mechanical devices such as spacers, or agents that will fuse vertebral bodies.

Abstract: A device and method of positioning materials in a spine using an arcuate tool and introducer. Materials may be positioned as desired, such as against an inner annular wall of an intervertebral disc or vertebral body. The arcuate tool retains its predetermined arcuate shape when no pressure or force is applied to the tool, and is positioned by manipulating the tool relative to an introducer and the spine, with the introducer manipulated relative to the spine.

Abstract: A method of positioning an arcuate catheter against an inner annular wall of the disc, and particularly on the posterior and postero-lateral portions of the inner annulus of the disc, by arthroscopy is presented. The arcuate catheter retains its predetermined arcuate shape when no pressure or force is applied to the catheter. This present device and method require no forward tip pressure on the inner annular wall of a mammalian intervertebral disc. An arcuate sheath having a cutter is used to remove tissue from the inner annulus of the disc. In another embodiment an arcuate sheath is used to progressively remove material from the interior of the mammalian intervertebral disc. In yet another embodiment, an arcuate sheath and catheter are used to remove the entire intervertebral disc and place supports to maintain a disc space.
