A catheter and handle assembly for use in treating tissue. More specifically, the invention relates to a catheter assembly having an elongate shaft, ablation assembly coupled to one end of the shaft, and a handle coupled to the other end of the shaft. The handle facilitates both axial and circumferential positioning of the ablation assembly via the shaft in an airway, conduit, or vessel for treatment of the tissue. Embodiments include the use of a handle to facilitate the axial and circumferential positioning of the shaft and ablation assembly through and independent of a working channel of a bronchoscope during treatment for pulmonary disease like COPD and asthma.
