1. A system for delivering power to a therapeutic device, comprising:
- a generator including a power regulation circuit for producing an output power at a generator output;
a patient cable having a proximal end configured for coupling to the generator output, and a distal end configured for coupling to a therapeutic device; and
a feedback apparatus connected to the distal end of the patient cable, the feedback apparatus comprising a current sensor, and configured to generate a feedback signal based on a current sensed by the current sensor;
wherein the power regulation circuit is configured to compensate for a power change along the patient cable by controlling the output power based at least in part on the feedback signal.

Abstract
A method and system for delivering power over a patient cable to a therapeutic device, in which a variable that depends on the delivered power is sensed or measured near a distal end of the patient cable, and a feedback signal is generated based on the sensed or measured value. The delivered power is adjusted based at least in part on the feedback signal to compensate for power variance along the patient cable.
