1. A radiofrequency (RF) ablation system for performing an RF ablation procedure, the RF ablation system comprising:
an energy source for delivering energy to a target site of a patient's body;
an energy delivery device electrically coupled to the energy source;
two or more sensors for measuring at least two factors, respectively, related to the RF ablation procedure; and
at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
operating the energy delivery device to deliver energy to create a lesion at the target site within the patient based on a first factor of the at least two factors;
while delivering energy to the target site, monitoring the at least two factors related to the RF ablation procedure based on measurements from the two or more sensors;
determining whether the first factor of the at least two factors has reached a first operating threshold for the energy delivery device responsive to a determination that measurements of the first factor have stabilized;
increasing or decreasing the energy delivered to the target site responsive to a determination that the first factor has not reached the first operating threshold;
switching control of the energy delivery device from the first factor to a second factor of the at least two factors once the first operating threshold has been met by the first factor to further develop the lesion at the target site within the patient;
determining whether the second factor of the at least two factors has reached a second operating threshold for the energy delivery device responsive to a determination that measurements of the second factor have stabilized;
increasing the energy delivered to the target site responsive to a determination that the second factor has not reached the second operating threshold; and
terminating the delivery of energy to the target site once the second operating threshold has been met by the second factor.
