Abstract: A cryoablation catheter for treatment of hypertrophic cardiomyopathy is disclosed. The cryoablation catheter includes: a vacuum zone provided therein with an inlet into which liquid coolant is injected and an outlet from which the liquid coolant discharged, wherein rest parts other than the inlet and the outlet therein are maintained in a vacuum state; a body part separated from the vacuum zone and provided at the front end thereof, wherein an end of the inlet and an end of the outlet communicate with each other, and wherein the body part includes a freeze zone for cooling surroundings by expanding of the liquid coolant exiting through a tip provided at the end of the inlet; and a tapered tip provided at an end of the body part, wherein a guidewire lumen for insertion of a guidewire thereinto is provided, and wherein the tapered tip is tapered toward an end thereof.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a method for positioning a tip of a pacemaker lead that has passed through coronary sinus into an interventricular septum. More particularly, it relates to a method for positioning a tip of a pacemaker lead that has passed through a coronary sinus into an interventricular septum in order to more effectively transmit an electrical stimulus in a treatment using a pacemaker for patients with arrhythmia. A method of positioning a tip of a pacemaker lead, which has passed through a coronary sinus, into an interventricular septum, in order to effectively transmit electrical stimulus, includes: inserting into an intervention wire through a superior vena cava and a coronary sinus to pass through the interventricular septum and then guiding the intervention wire to an inferior vena cava; and positioning the tip of the lead into the interventricular septum by inserting the pacemaker lead along the intervention wire.

Abstract: The present invention relates to a device for transcatheter treatment for tricuspid regurgitation. The device for transcatheter treatment for tricuspid regurgitation, according to one preferred embodiment of the present invention, includes: the coronary sinus tube inserted into the coronary sinus; and the tricuspid valve tube traversing the tricuspid valve, wherein the coronary sinus tube and the tricuspid valve tube communicate with each other or are adjacent to each other within a range of predetermined length at an upper side and are separate from each other at a lower side, and a blocking member for blocking a space generated by incomplete closing of the tricuspid valve is provided at a lower part of the tricuspid valve tube or between the coronary sinus tube and the tricuspid valve tube.

Abstract: A mitral cerclage annuloplasty apparatus comprises a tissue protective device and a knot delivery device. The tissue protective device comprises a first protective tube and a second protective tube. The knot delivery device comprises a tube wherein a loose knot is looped around its distal end through a hole and wherein tight knot is formed when the distal end of the tube is cut open. Alternatively, the knot delivery device comprises an inner tube and outer tube. The inner tube is insertable and rotatable inside the outer tube. When the tubes are in a closed position by rotating either the outer tube or the inner tube, a hole is created near its distal end. When the tubes are in open position by rotating either the outer tube or the inner tube, the hole joins the opening of the outer tube and lengthens.

Abstract: The present invention relates to a tissue protection device for tricuspid regurgitation surgery and, more particularly, to a tissue protection device for surgery on patients suffering from tricuspid regurgitation. The tissue protection device for tricuspid regurgitation surgery according to a preferred embodiment of the present invention includes: a hollow coronary sinus tube (22) for protecting coronary sinus tissue; and a hollow tricuspid valve tube (24) for protecting tricuspid valve tissue and interventricular septum tissue, wherein the coronary sinus tube and the tricuspid valve tube are laterally coupled with each other from upper portions thereof by a predetermined length, and lower portions thereof are separated from each other; and the lower portion of the tricuspid valve tube (24) is provided with a blocking part (30) for blocking a space resulting from incomplete closure of the tricuspid valve.
