Atrial fibrillation catheter and method of atrial fibrillation using it

摘要

PROBLEM TO BE SOLVED: To provide an atrial fibrillation operation catheter for performing atrial fibrillation of the heart. SOLUTION: One or more ablation electrodes are formed in a distal portion, and a fuselage portion forming a catheter body made of a soft soft material, and a tapered tip connected to the body portion and tapering toward the end. Although included, a guide wire lumen into which the guide wire is inserted is formed by being connected to the tip and the body portion. The method of performing atrial fibrillation for performing the preferred cardiac atrial fibrillation of the present invention is a step of inserting a guide wire from the superior vena cava or the inferior large vein into the Marshall vein through the coronary sinus, and the guide wire is guided far away. The stage of locating the RF ablation catheter with the ablation electrode formed in the position in the Marshall vein, and the stage of performing RF ablation around the Marshall vein after connecting the RF ablation catheter to the RF generator. include.
