Abstract: A system includes a pulse waveform generator and an ablation device coupled to the pulse waveform generator. The ablation device includes at least one electrode configured for ablation pulse delivery to tissue during use. The pulse waveform generator is configured to deliver voltage pulses to the ablation device in the form of a pulsed waveform. The pulsed waveform can include multiple levels of hierarchy, and multiple sets of electrodes can be activated such that their pulsed delivery is interleaved with one another.

Abstract: Systems, devices, and methods for electroporation ablation therapy are disclosed herein, with a cinch device for positioning an ablation catheter relative to tissue during a cardiac ablation procedure. In some embodiments, a distal end of a first device may be advanced into a proximal end of a first lumen of a second device. The first device may be advanced from a distal end of the first lumen and the first device may be looped around tissue of a patient. The first device may be advanced into a distal end of a second lumen of the second device. The distal end of the first device may be advanced from a proximal end of the second lumen. The proximal and distal ends of the first device may be advanced away from a proximal end of the second device to increase contact between the first device and the tissue.

Abstract: Systems, devices, and methods for electroporation ablation therapy are disclosed, with the device including a set of splines coupled to a catheter for medical ablation therapy. Each spline of the set of splines may include a set of electrodes formed on that spline. The set of splines may be configured for translation to transition between a first configuration and a second configuration. The devices described herein may be used to form a lesion via ablation by irreversible electroporation.

Abstract: Systems, tools and methods are disclosed for the selective and rapid application of DC voltage to drive irreversible electroporation, with the system controller capable of being configured to apply voltages to independently selected subsets of electrodes and capable of generating at least one control signal to maintain the temperature near an electrode head within a desired range of values. Electrode clamp devices are also disclosed for generating electric fields to drive irreversible electroporation while modulating temperature to elevate the irreversible electroporation threshold utilizing a variety of means such as cooling fluid or solid state thermoelectric heat pumps.
