Abstract
The present invention provides a bipolar radiofrequency ablation catheter comprising a working catheter and a magnetic catheter. The magnetic catheter comprises a first tube; a magnet; a first electrode; and a first electrode connector, and the working catheter comprises a second tube; a metallic element; a second electrode; and a second electrode connector. According to the present invention, it is possible to create transmural lesions more completely and easily at a thick myocardial region such as left ventricle in which a transmural lesion could not be easily created by using conventional radiofrequency ablation catheters and thus it is expected to increase the treatment efficiency for tachycardia such as ventricular tachycardia and atrial fibrillation.
