An RF catheter for treating hypertrophic cardiomyopathy includes: a body part constituting a catheter body made of a flexible and soft material; and an intraseptal insertion part provided at a distal part of the body part and having one or more electrodes, a tapered tip gradually becoming thinner toward an end thereof, and a guidewire lumen therein, into which a guidewire is inserted, so that during hypertrophic cardiomyopathy treatment, the intraseptal insertion part is inserted into the interventricular septum along the guidewire. A method of treating hypertrophic cardiomyopathy by using an RF ablation catheter includes: i) positioning the guidewire to a hypertrophied septum through a coronary sinus and a septal vein; ii) transferring the RF ablation catheter to the hypertrophied septum; and iii) performing RF ablation by applying RF energy to the electrodes provided at an end part of the RF ablation catheter by using an RF generator.

The present disclosure relates to a RF ablation catheter for septal reduction therapy having a cooling effect, and more particularly, to a RF ablation catheter for septal reduction therapy that is for performing RF ablation, in which RF energy is applied to an interventricular septum, for septal reduction therapy such as therapy for hypertrophic cardiomyopathy, which is a disease in which an interventricular septum of the left ventricle of the heart of the animal or human body thickens, therapy that requires reduction of an interventricular septum, or therapy for ventricular tachycardia. Also, the present disclosure relates to a RF ablation catheter for septal reduction therapy having a cooling effect that is for preventing carbonization of a tissue of the body (interventricular septum) around an electrode. An exemplary embodiment of the present disclosure provides a RF catheter for septal reduction therapy, the RF catheter including: an intra-septal part in which a tapered tip which becomes thinner toward an end thereof is formed at an end of a distal part and one or more electrodes are formed at positions on an outer circumferential surface that are adjacent to the tip; and a body part which is made of a soft material and has a guidewire lumen which passes through the intra-septal part from an inlet formed at the center of the end of the tip and has an outlet formed in a side surface, a coolant inlet lumen which is connected from a proximal part to an inner portion of the intra-septal part to allow a coolant to be injected from the outside and which has an open end, and a coolant outlet lumen which communicates with the coolant inlet lumen and has an exit formed in a side surface, wherein the guidewire lumen and the coolant inlet lumen do not communicate with each other and are partitioned from each other.

A pacemaker lead for cerclage pacing includes a lead fixing part including a fixing tip whose diameter becomes gradually smaller toward an end of a distal part thereof, a plurality of bipolar electrodes that come into close contact with heart muscle, in an outer circumference of the lead fixing part, and a guide wire insertion through hole through which a guide wire can be inserted thereinto, a lead body part configured to be extended to the lead fixing part, having a stylet insertion through hole formed therein, and a body fixing part formed in a bent shape so as to be fixed to an inner wall of the coronary sinus, and a stylet inserted into the stylet insertion through hole, enabling the pacemaker lead for cerclage pacing to be easily moved within the body of the patient.
