1. An electrosurgical generator comprising:
one or more ports adapted to receive one or more electrosurgical probes, each port comprising a contact, wherein the electrosurgical generator includes at least two contacts;
a high voltage power source;
a delivery circuit comprising a plurality of switches configured to route an output from the high voltage power source to selected contacts of the one or more ports;
a controller having stored instructions that can be selected, configured or adjusted by a user, the stored instructions including a therapy instruction set for delivering a therapy regimen, the therapy regimen comprising a series of pulses each having a pulse width, the series of pulses forming a burst, the therapy instruction set defining how many pulses are in each burst and defining how many bursts are to be delivered in the therapy regimen;
a trigger adapted to sense or receive a triggering signal from a patient, the trigger configured to identify a therapy window for delivery of a burst defined by the therapy regimen and command the delivery circuit to route the output to selected contacts during the therapy window,
wherein the controller further includes a stored timer instruction set adapted to determine time remaining for the therapy regimen by determining a trigger rate using data from the trigger, and calculate how much time will be required to complete remaining bursts of the therapy regimen in light of the trigger rate; and
a user interface having a display section that displays to a user an estimated remaining time as calculated by the controller executing the stored timer instruction set.
