摘要
The present invention relates to a cryoablation catheter for hypertrophic cardiomyopathy and a hypertrophic cardiomyopathy cryoablation procedure using the same. The present invention relates to a cryoablation catheter for hypertrophic cardiomyopathy and a method of cryoablation using hypertrophic cardiomyopathy using the same for applying cold refrigerant damage to the hypertrophic myocardium by applying a refrigerant through the insertion. In the cryoablation catheter for the hypertrophic cardiomyopathy procedure of the present invention, an injection tube through which a fluid is injected and a discharge tube through which the fluid is discharged are installed, and a portion other than the injection tube and the discharge tube maintains a vacuum state, and the vacuum It is separated from the region and is installed at the front end, the end of the injection pipe and the end of the discharge pipe are in communication with each other, and includes a refrigeration zone that cools the surroundings while the fluid exiting through the tip formed at the end of the injection pipe expands. Body part; And a tapered tip formed at an end of the body portion, a guide wire lumen for inserting a guide wire therein, and tapering toward the end.
