AI Technical Summary
Technical Problem
High-pressure pulses in body fluids (such as blood) lead to electrolyte decomposition and bubble generation, causing adverse reactions such as bubble formation and lightning arc discharge, affecting the effective ablation of heart tissue.
Method used
Electrodes with convex edges containing concave and convex portions are used to generate a more uniform electric field and reduce the concentration of electric field strength at the edge of the electrode through the special shape of the electrode, thereby reducing the occurrence of bubbles and lightning arcs.
Benefits of technology
It effectively reduces bubbles and lightning arcs when high-pressure pulses are used in cardiac tissues, and improves the safety and efficiency of tissue ablation.

Abstract
To provide contoured electrodes for pulsed electric field ablation, and systems, devices, and methods thereof.SOLUTION: Systems, devices, and methods are provided herein for delivering pulsed electric fields to ablation tissue (e.g., cardiac tissue). An ablation device can include one or more contoured electrodes with contoured edges that are disposed on an insulating member of the ablation device. The contoured electrodes can be configured to reduce an electric field intensity at an interface between the contoured electrodes and the insulating member and / or a drop-off in electric field intensity.SELECTED DRAWING: Figure 1
