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: Novel and versatile apparatuses for delivering one or more of thermal ablation and irreversible electroporation therapies to target tissue. In some examples, a device includes at its distal end a plurality of electrodes that can be advanced or retracted to pierce patient tissue, with a variable position and size shaft electrode provided near the distal end of the device to allow manipulation of therapy fields to achieve various tissue destruction field shapes. A number of method of use examples are described as well.

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: Biological cell destruction is achieved through a combination of injection of a substance and application of an electrical field. The substance, such as a cationic polymer, is selected for its electrical characteristics which can add to the transmembrane electric field of a cell when the electrical field is applied. In some examples, electrical field application is performed to encourage spatial concentration of the injected substance favorable to increased transmembrane field strength. The biological cell or cells are destroyed primarily through irreversible electroporation.

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.
