RF ablation catheter for hypertrophic cardiomyopahty and method for hypertrophic cardiomyopahty in use of it

摘要

RF catheter for the treatment of hypertrophic cardiomyopathy according to the present invention comprises a body portion forming a soft soft material catheter body; And formed on the distal portion of the body, at least one electrode is formed, tapered tip is formed tapering toward the end, the guide wire lumen to insert the guide wire is formed inside, guide wire during hypertrophic cardiomyopathy It includes; the septum insertion portion is inserted into the ventricular septum. The method for the treatment of hypertrophic cardiomyopathy using the RF electrode ablation catheter of the present invention includes: i) positioning a guidewire in a hypertrophied septum enlarged through a coronary sinus and a septal vein; ii) passing the RF electrode ablation catheter with the guide wire lumen formed along the guide wire to the enlarged ventricular septum; And iii) in a state in which a coolant is continuously injected into the RF electrode ablation catheter, an RF electrode is applied by applying RF energy to an electrode formed at the end of the RF electrode ablation catheter using an RF generator. And performing resection.
