Abstract: A method and system for mapping an anatomical structure includes sensing activation signals of intrinsic physiological activity with a plurality of mapping electrodes disposed in or near the anatomical structure. The activation signals are used to determine a dominant frequency for each electrode from which a wavefront vector for each electrode is determined based on a difference between the dominant frequency at a first electrode location and the dominant frequency at neighboring electrodes. An anatomical map is generated based on the determined wavefront vectors.

Abstract: An electroporation ablation system for treating targeted tissue in a patient. The electroporation ablation system including an ablation catheter and an electroporation generator. The ablation catheter including a handle, a shaft having a distal end, and catheter electrodes situated at the distal end of the shaft and spatially arranged to generate electric fields in the targeted tissue in response to electrical pulses. The electroporation generator operatively coupled to the catheter electrodes and configured to deliver the electrical pulses in an electroporation pulse sequence to one or more catheter electrodes. Wherein, the electroporation pulse sequence includes multiple pulse bursts, and each of the multiple pulse bursts includes pulses separated by an inter-pulse length of between 200 and 350 microseconds to reduce muscle stimulation while creating electroporation lesions.

Abstract: Methods and systems for cardiac mapping are disclosed. An example system includes a catheter shaft with one or more electrodes coupled to a distal end of the catheter shaft. Electrodes sense electrical signals at anatomical locations within a heart. A processor coupled to the catheter shaft acquires electrogram signals of the heart using the electrodes. Each electrogram signal relates to three-dimensional positional data corresponding to the anatomical locations. The processor also store the electrogram signals of the heart corresponding to electrical activities sensed at corresponding anatomical locations, calculate an activation recovery interval associated with each of the corresponding anatomical locations, determine spatial gradient data of the activation recovery interval based on a distance between at least two neighboring anatomical locations. The system also includes a display device to display a three-dimensional graphical representation of the spatial gradient data between the at least two neighboring anatomical.

Abstract: A catheter system includes a catheter comprising a tip assembly, the tip assembly having a plurality of electrodes and the plurality of electrodes are configured to measure electrical signals. The system also includes a processing unit configured to: receive a first electrical signal sensed by a first electrode of the plurality of electrodes and a second electrical signal sensed by a second electrode of the plurality of electrodes. A first vector is determined based on the first electrical signal that corresponds to the first electrode. A second vector is determined based on the second electrical signal that corresponds to the second electrode. A resultant vector is determined by summing at least the first vector and the second vector, wherein the resultant vector is indicative of the orientation of the tip assembly.
