Abstract

A method and system for automated and semi-automated predictable, consistent, safe, effective, and lumen-specific and patient-specific cryospray treatment of airway tissue in which treatment duration is automatically set by the system following entry of patient information and treatment location information into the system by the user, and treatment spray is automatically stopped by the system when the automatically selected treatment duration has been achieved as determined by the system.
