  • Publication number: 20200138506
    Abstract: Methods and systems for monitoring and modifying pulsed field ablation (PFA) energy delivery to prevent patient safety risks and/or delivery device failure. In particular, some embodiments provide methods and systems for detecting and preventing arcs and arc-induced plasma, and their causal events, during delivery of pulsed field ablation energy, as well as methods and systems for identifying conditions leading to potential delivery device failure and correcting charge imbalance or asymmetry.

  • Publication number: 20200121382
    Abstract: Systems and methods to confirm safe delivery of treatment energy to a patient by identifying a presence of a fault in an energy delivery pathway and identifying a location of the fault within the device. The system includes a processing unit configured to calculate blood impedances external to the device based on known impedance characteristics of the device, and then to calculate impedances within the device during energy delivery based on the calculated blood impedances. The processing unit prevents the delivery of energy in an energy delivery pathway that is determined to be compromised. The processing unit is also configured to compare times for two different frequencies to travel a predetermined distance, the difference in the times corresponding to a location of a fault within the energy delivery pathway.

  • Publication number: 20180214195
    Abstract: A system and method for the safe delivery of treatment energy to a patient, which includes verification of system integrity before, during, or after the delivery of treatment energy and provides several mechanisms for rapid termination of the delivery of potentially harmful energy to the patient when a fault condition in the device and/or system is identified. The system may include an energy generator having processing circuitry to determine if there is a fault condition in the system and to automatically terminate a delivery of treatment energy when the processing circuitry determines there is a fault condition. The method may generally include performing a series of pre-checks, synchronizing a treatment energy delivery to the proper segment of the heart's depolarization pattern, configuring the system for treatment energy delivery, delivering the treatment energy, and performing post-treatment evaluation.

  • Publication number: 20170095290
    Abstract: Methods and systems for combining ablation therapy with navigation of the ablation device. An ablation system may be configured for use with one of two methods to prevent loss of navigation signals during ablation energy delivery. In the first method, ablation energy signals are filtered from the navigation signal. In the second method, the delivery of ablation energy is sequenced with the delivery of navigation energy such that ablation energy and navigation energy are not delivered at the same time and navigation signals received by the system are time-division multiplexed to reconstruct the navigation signals and determine a location of the device within the patient.
