Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for electroporation ablation. The electroporation catheter may include an electrode assembly comprising one or more ablation electrodes configured to generate electric fields proximate to target tissue in response to a plurality of electrical pulse sequences delivered in a plurality of therapy sections, and one or more mapping electrodes configured to measure cardiac electrical signals. In some embodiments, the measured electrical signals are used to create an electro-anatomical map.

Abstract: At least some embodiments of the present disclosure are directed to an electroporation ablation system for treating targeted tissue in a patient. The electroporation ablation system comprises an ablation catheter including catheter electrodes configured to generate electric fields in the targeted tissue in response to a plurality of electrical pulse sequences delivered in a plurality of therapy sections; a controller configured to receive a first pulse voltage of a first electrical pulse sequence measured during a first therapy section of the plurality of therapy sections; and determine a charge voltage based on the first pulse voltage; and an electroporation generator. The electroporation generator is operatively coupled to the catheter electrodes and the controller and configured to deliver a second electrical pulse sequence at a controlled pulse voltage for a second therapy section of the plurality of therapy sections.

Abstract: An electroporation catheter for ablation of cardiac tissue is disclosed. The electroporation catheter includes an elongated shaft having a proximal end and an opposite distal end. The elongated shaft defines an axis. An electrode assembly is coupled to and extends distally from the distal end of the elongated shaft. The electrode assembly is transitionable between a collapsed state and an expanded state. The electrode assembly includes conductive struts that define a spherical shape in the expanded state having a proximal portion coupled to the elongated shaft, a central portion having a maximum radial dimension and a distal portion opposite the elongated shaft. A proximal insulation portion is disposed on the proximal portion of the electrode assembly surrounding each of the plurality of conductive struts. The proximal insulator portion extends from the proximal end to at least the central portion.

Abstract: A system for facilitating an ablation in a patient's heart is disclosed. The system includes a catheter and a controller. The catheter includes an electrode assembly having spaced-apart electrodes disposed on splines to generate an electric field in the heart, the splines configurable in an expanded position wherein the plurality of spaced-apart electrodes are in a selected spatial relationship, and wherein the splines are deformable relative to the expanded configuration when subjected to a force. The controller is configured to measure an electrical signal received from an electrode of the spaced-apart electrodes in response to the electric field, the electrical signal indicative of a parameter of the electric field, and the controller configured to determine a deformation of the splines relative to the expanded position based on the measured electrical signal.
