Abstract
The present disclosure provides electroporation systems, methods of controlling electroporation systems to limit electroporation arcs through intracardiac catheters, and catheters for electroporation systems. One method of controlling an electroporation system including a direct current (DC) energy source, a return electrode connected to the DC energy source, and a catheter connected to the DC energy source is disclosed. The catheter has a at least one catheter electrode. The method includes positioning the return electrode near a target location within a body and positioning the catheter electrode adjacent the target location within the body. A system impedance is determined with the return electrode positioned near the target location and the catheter electrode positioned within the body. The system impedance is adjusted to a target impedance to arcing from the catheter electrode.
