Abstract: Catheter systems, tools and methods are disclosed for the selective and rapid application of DC voltage to drive irreversible electroporation, with the system controller configurable to apply voltages to an independently selected subsets of electrodes, such that voltages of one polarity are applied to a multiplicity of electrodes on a first medical device and voltages of the opposite polarity to a multiplicity of electrodes on a second medical device. The first and second medical devices can be epicardial catheters positioned such that their opposing distal tips are approximately aligned and whose segments with electrodes collectively wrap around the pulmonary veins.

Abstract: An electroporation catheter for facilitating ablation of cardiac tissue is disclosed. The electroporation catheter includes an elongated shaft having a distal region. An inflatable member and electrode assembly are coupled to the distal region. The inflatable member is transitionable between an inflated configuration and an uninflated configuration. The electrode assembly includes electrodes and flexible support members. The electrodes include sensing electrodes disposed on the flexible support members and ablation electrodes configured to generate an electric field. The flexible support members are transitionable between an expanded configuration and a collapsed configuration. The flexible support members form a cavity, and the inflatable member is disposed within the cavity.

Abstract: Systems, devices, and methods for electroporation ablation therapy are disclosed, with the system including a pulse waveform signal generator for medical ablation therapy that may be coupled to an ablation device including at least one electrode for ablation pulse delivery to tissue. The signal generator may generate and deliver voltage pulses to the ablation device in the form of a pulse waveform in a predetermined sequence where the signal generator may independently configure a set of electrodes of an ablation device. The signal generator may further perform active monitoring of a set of electrode channels and discharge excess energy using the set of electrode channels.
