摘要：
The present invention relates to a double laso catheter, the body portion 100 constituting the main body of the catheter； An upper lyso 200 coupled to a portion of the main body 100 to measure a signal of the pulmonary vein or perform pulmonary vein isolation ceramic ablation； And a lower lyso 300 coupled to a portion of the main body 100 to measure a signal of the pulmonary vein or perform pulmonary vein isolation ceramic ablation. In addition, the present invention provides a method of using a double laso catheter, and more specifically, the main body portion 100 constituting the main body of the catheter； An upper lyso 200 coupled to a portion of the main body 100 to measure a signal of the pulmonary vein or perform pulmonary vein isolation ceramic ablation； And a lower laso 300 coupled to a portion of the main body 100 to measure a signal of the pulmonary vein or to perform pulmonary vein isolation ceramic ablation, comprising: (1) a main body. Inserting a catheter comprising a portion 100, an upper lyso 200 and a lower lyso 300 into a pulmonary vein； (2) detecting the signal of the pulmonary vein in the upper lyso 200 or the lower lyso 300 of the catheter inserted in step (1)； And (3) transferring high frequency energy from the upper laso 200 or the lower laso 300 of the catheter inserted in step (1) to perform high frequency electrode catheterization. According to the double laso catheter proposed in the present invention and a method of using the catheter, the catheter may include a laso having both a signal detection and a high frequency ceramic ablation function of the pulmonary vein, thereby performing a high frequency electrode ceramic ablation using a single instrument. Make sure In addition, according to the present invention, by including a lyso that detects the signal of the pulmonary vein and a lyso having a high frequency ceramic ablation function, respectively, during the procedure to reduce the hassle of having to put the catheter several times in
