Abstract
In a multi-electrode ablation system, method, and controller, a power supply is configured to be coupled to a plurality of electrodes, and a controller is coupled to the power supply. The controller is configured to couple an output voltage of the power supply to the plurality of electrodes, and for each electrode of the plurality of electrodes, measure a temperature associated with the electrode, and determine a thermal gain of each electrode of the plurality of electrodes.
Claims20
A multi-electrode ablation system comprising:
- a power supply configured to be coupled to a plurality of electrodes;
- and
- a controller coupled to the power supply, the controller configured to:
- couple an output voltage of the power supply to the plurality of electrodes;
- for each electrode of the plurality of electrodes, measure a temperature associated with said electrode;
- and
- determine a thermal gain of each electrode of the plurality of electrodes.
A method of operating a multi-electrode ablation system having a plurality of electrodes and a power supply configured to be coupled to the plurality of electrodes, the method comprising:
- coupling an output voltage of the power supply to the plurality of electrodes;
- for each electrode of the plurality of electrodes, measuring a temperature associated with said electrode;
- and
- determining a thermal gain of each electrode of the plurality of electrodes.
A method of sampling a periodic, time invariant signal having a known frequency, the method comprising:
- sampling the signal at a substantially fixed frequency during a first plurality of periods of the signal to collect a plurality of samples of the signal, wherein each sample includes a phase of the signal and an amplitude of the signal, wherein the substantially fixed frequency is selected to collect one or more samples during each period of the signal at a different phase of the signal than samples collected during an immediately prior period of the signal;
- combining the plurality of samples collected over the first plurality of periods of the signal as a function of the phase of the signal to produce a representation of a single period of the signal.
A controller comprising:
- a processor;
- and
- a memory device, the memory device including instructions that, when executed by the processor, cause the processor to:
- sample a periodic, time invariant signal at a substantially fixed frequency during a first plurality of periods of the signal to collect a plurality of samples of the signal, wherein each sample includes a phase of the signal and an amplitude of the signal, wherein the substantially fixed frequency is selected to collect one or more samples during each period of the signal at a different phase of the signal than samples collected during an immediately prior period of the signal;
- combine the plurality of samples collected over the first plurality of periods of the signal as a function of the phase of the signal to produce a representation of a single period of the signal.
