Abstract
Methods and systems for ablating target tissue, such as in or along an airway, include modulation one of power and current of an a system to achieve a treatment output or parameter. Treatment outputs can include current, power, energy delivered, percent drop in impedance, an impedance-based ratio, a percent impedance slope, and/or an airway wall impedance. Power and/or current of the system can be varied, within certain maximum thresholds, such as power, current, and/or impedance thresholds, to achieve the desired output parameter target during some or all of the treatment time. The systems and methods reduce the variability of the treatment efficacy otherwise due to variability in electrical properties of patient tissue and/or electrode contact.
