Embodiments of a system and method are described for delivering energy to a body of a human or animal through a plurality of energy delivery devices. In some embodiments, a plurality of energy delivery devices are coupled to a generator and the number of energy delivery devices is automatically detectable. Furthermore, in some embodiments, the amount of energy delivered through the energy delivery devices is controlled, at least in part, by dynamically varying the amount of time that each energy delivery device is delivering energy.
