Abstract: At least some embodiments of the present disclosure are directed to systems and methods for estimating locations of electrodes and/or electrode assembly of an electroporation ablation catheter using one or more navigation sensors integrated with the catheter. In some examples, the electrode assembly includes a plurality of splines and a navigation sensor is disposed on or integrated with one of the plurality of splines. In some examples, a navigation sensor is disposed on o integrated with a supporting structure of the catheter.

Abstract: At least some embodiments of the present disclosure are directed to systems and methods for estimating locations of electrodes and/or electrode assembly of an electroporation ablation catheter when the catheter is deployed. In some examples, the electrode position is estimated using electrical signals collected when a current is injected via tracking electrodes. In certain examples, the electrode positions are updated using one or more geometric models associated with the electroporation ablation catheter.

Abstract: A system for electroporation ablation including a catheter having an electrode assembly and one or more states. The electrode assembly may be in different shapes when the catheter is at different states. The controller is configured to generate, based on one or more models of electric fields, graphical representations of electric fields generated by the electrode assembly when the catheter is at different states. In some embodiments, the controller is configured to overlay the graphical representations of the one or more electric fields on an anatomical map of a patient.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods apparatus for performing at least one of mapping and ablation functions. The apparatuses, systems, and methods may include a catheter sized and shaped for vascular access having a tip section that forms closed loop. The apparatuses, systems, and methods may also include one or more electrode structures arranged with the closed loop.

Abstract: Embodiments of the present invention provide an irrigated ablation electrode assembly for use with an irrigated catheter device comprises at least one passageway for a fluid with an outlet disposed at an external surface of the electrode assembly; a permanent magnet; a shield separating the permanent magnet from the at least one passageway and from an exterior, the shield being substantially less oxidizable than the permanent magnet; and an electrode having an external electrode surface. A catheter guidance control and imaging system drives the permanent magnet to guide and control the catheter tip. In specific embodiments, the irrigation fluid flow paths through the electrode assembly are thermally insulated from the electrode and temperature sensor. The irrigation fluid is directed at target areas where coagulation is more likely to occur. One or more monitoring electrodes are provided for mapping or other monitoring functions.
