Abstract
A tissue evacuation device may be designed to provide a high-energy fluid (e.g., a heated vapor) to targeted tissue for breaking down the targeted tissue, such as the nucleus of an intervertebral disc. An inner tube positioned within an outer tube, having a nozzle coupled to distal ends of the tubes, having a heating element positioned between the inner and outer tubes, delivers a heated vapor through a port to the nozzle to break down tissue. After the nucleus or other targeted tissue is broken down, the tissue evacuation device may also remove some or all of the broken down tissue.
