ABSTRACT:
A system for heat ablation of tissue in which energy is sequentially applied to at least two electrodes inserted into tissue, the system comprising a radiofrequency source configured to supply radiofrequency energy to two or more electrodes, at least one return electrode for returning the RF energy to the RF source, and a controller configured to sequentially apply the RF energy to each of the two or more electrodes for a predetermined period of time. The controller includes a determiner configured to determine an off time for a next electrode in a sequence and a comparator configured to compare the off time for the next electrode in the sequence to a predetermined minimum off time. The controller applies the radiofrequency energy to the next electrode in the sequence when the off time is greater than the predetermined minimum off time.
