Abstract: Electrosurgical generators having improved functionality and a user interface. In an example, the user may modify therapy output parameters without interrupting therapy delivery within a therapy regimen by accessing a change tool on the user interface, with the change tool operable to change a stack selector configuration. In an example, the display shows both therapy amplitudes and encountered impedances for a plurality of therapy pulses in different portions of a display.

Abstract: Methods and devices for performing ablation using time multiplexed waveforms are disclosed. The increased efficacy of monophasic waveforms is combined with the reduced side effects of biphasic waveforms by distributing components of the waveform across over a broader time interval than that typically used in a conventional biphasic waveform. Charge balancing occurs upon completion of therapy delivery within a time period that avoids muscle stimulation, while allowing unbalanced waveforms to be delivered during stimulation.

Abstract: Methods and devices for issuing ablation therapy using a cardiac signal as a trigger for therapy delivery. The cardiac signal itself may be analyzed before and/or between pulsed electrical field outputs to determine when, relative to fiducials within the cardiac signal, the output can safely be delivered. In some examples, the timing of therapy delivery is tailored to the patient's current cardiac state, such as the cardiac rate. In other examples, triggering signals can be analyzed to ensure that the trigger itself is appropriately detected.

Abstract: Ablation probes and methods of their use. Example probes include probe circuits configured to provide identifying information for the probe itself. The probe circuits may sense probe usage and/or age to determine probe end of life (EOL). In response to EOL, the probe circuit generates an output indicating EOL. The probe electronic circuit may also be configured to monitor probe usage via impedance or other features, independent of such operation by an ablation pulse generator.

Abstract: Methods and devices for performing ablation. In some examples an ablation delivery system is configured to allow separate voltage levels of a capacitor stack to be accessed for use in therapy delivery. Ablation therapy systems switchable between current and voltage controlled output are described. Methods of treating a patient using adjustable interphase or interpulse delay are disclosed as well.

Abstract: Systems and methods for performing and controlling ablation therapy. Examples provide adaptive therapy outputs that allow a user to select among various feedback parameters, parameter limits, and therapy profiles, to be implemented by an ablation system. The ablation system adaptively issues therapy by monitoring one or more feedback parameters to determine changes to make to therapy outputs.

Abstract: Electrosurgical generators having improved functionality and user interface. In an example, the user may modify therapy output parameters without interrupting therapy delivery within a therapy regimen. In an example, the display shows both therapy amplitudes and encountered impedances for a plurality of therapy pulses in different portions of a display. In an example, the electrosurgical generator is operable in a triggered mode using a cardiac signal trigger and provides the operator with an estimate of remaining time that is calculated in light of a calculated cardiac rate.

Abstract: Methods and devices for performing ablation using spatially multiplexed waveforms are disclosed. The increased efficacy of monophasic waveforms is combined with the reduced side effects of biphasic waveforms by distributing components of the waveform across multiple electrodes. Charge balancing occurs upon completion of therapy delivery within a time period that avoids muscle stimulation, while allowing unbalanced waveforms to be delivered during stimulation.
