Patent number: 11931094Abstract: 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.Type: GrantFiled: October 14, 2020Date of Patent: March 19, 2024Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Bruce R.

Publication number: 20210322086Abstract: 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.Type: ApplicationFiled: April 20, 2021Publication date: October 21, 2021Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: JONATHAN TYLER GORZYCKI, HONG CAO, BRUCE R.

Publication number: 20210298822Abstract: 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.Type: ApplicationFiled: March 30, 2021Publication date: September 30, 2021Applicant: Boston Scientific Scimed, Inc.Inventors: TIMOTHY A.

Publication number: 20200289827Abstract: 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.Type: ApplicationFiled: March 13, 2020Publication date: September 17, 2020Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: BRUCE R.
