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.
Claims28
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 the therapeutic device;
- and
- a feedback apparatus coupled to one or both of the patient cable and the therapeutic device, the feedback apparatus configured to sense at least one variable that depends on a delivered power and to generate a feedback signal depending on the delivered power, the power regulation circuit controlling the output power based at least in part on the feedback signal.
