Cryoablation catheter for hypertrophic cardiomyopahty

摘要

The present invention relates to a cryo-resection catheter for hypertrophic cardiomyopathy and a method of cryo-resection for hypertrophic cardiomyopathy using same The present invention relates to a cryo-resection catheter for hypertrophic cardiomyopathy, and a cryo-resection method for hypertrophic cardiomyopathy using the same, for inflicting cold damage to the enlarged myocardium by inserting and applying a refrigerant through it. The cryoablation catheter for hypertrophic cardiomyopathy of the present invention has an injection tube into which a fluid is injected and a discharge tube through which the fluid escapes, and a portion other than the injection tube and the discharge tube has a vacuum area maintaining a vacuum state, and It is separated from the region and installed at the front end, and the end of the injection pipe and the end of the discharge pipe are in communication with each other, and a refrigeration region that cools the surroundings while expanding the fluid exiting through the tip formed at the end of the injection pipe. Body part; And a tapered tip formed at an end of the body portion and having a guide wire lumen for inserting the guide wire therein, and tapering toward the end.
