1. A method for forming an arcuate shaped lesion at a target tissue location using an ablation instrument that has an energy emitter that is configured to move in a sweeping motion to form the arcuate shaped lesion in target tissue at the target tissue location comprising the steps of:
inputting a preselected power level of the energy emitter;
selecting a start point of the energy emitter to begin the sweeping motion;
initiating energy delivery and commencing the sweeping motion of the energy emitter beginning at the start point and under operation of a first motor; and
terminating the energy delivery and sweep once a desired end point is reached based on visual observation of an image of the arcuate shaped lesion formed in the target tissue that is obtained in real time with a visualization device;
wherein the ablation instrument includes a manual override knob that allows manual control over rotational and axial movement of the energy emitter and the motor has an override mode that maintains delivery of energy from the energy emitter and maintains the sweeping motion of the energy emitter even if the manual override knob is moved.
