RF ablation catheter for treating hypertrophic cardiomyopathy

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 distalpart 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.

Description

technical field [0001] The present invention relates to a radiofrequency ablation catheter (RF ablation catheter) for hypertrophic cardiomyopathy surgery and a method for using it, and relates to a hypertrophic cardiomyopathy surgery for the left ventricular septal thickening disease of animals or human hearts, which is used to implement A radiofrequency catheter for radiofrequency ablation of radiofrequency energy into the interventricular septum for hypertrophic cardiomyopathy surgery and a method of use thereof. Background technique [0002] The so-called hypertrophic cardiomyopathy refers to a heart disease in which the walls of the left ventricle thicken in the absence of other signs such as aortic valve stenosis or high blood pressure sufficient to induce left ventricular hypertrophy. Found in 1 in every 500 people in the whole population, various forms of left ventricular hypertrophy were observed. The most common and typical features are asymmetrical septal hypertro...
