Mechanism of action

The ESP (Electrosurgical Pulmonary vein isolation) Catheter delivers controlled radiofrequency energy through its tip to ablate abnormal cardiac tissue, particularly in the pulmonary veins and left atrium. This creates scar tissue that blocks the electrical signals responsible for atrial fibrillation, restoring normal heart rhythm. The device is designed to enable precise, efficient pulmonary vein isolation during catheter ablation procedures.
