Abstract

The invention relates to a catheter ablation device capable of forming a continuous ablation lesion and a radio frequency ablation catheter thereof. The radiofrequency ablation catheter includes a main body, an extension section, and an annular section connected in sequence; and an annular electrode disposed on the annular section, the annular electrode has an ablation portion, and the ablation portion is continuously formed on the annular paragraph. The radiofrequency ablation catheter of the present invention has continuous annular electrodes, and can form continuous annular ablation lesions with significantly reduced times of ablation.

Description

technical field [0001] The invention relates to medical equipment, in particular to a catheter ablation device and a radiofrequency ablation catheter thereof. Background technique [0002] Radiofrequency ablation catheter is a kind of electrophysiological catheter, which has been widely used in the treatment of arrhythmia in recent years. Generally speaking, the catheter includes two functions of mapping electrical signals and radiofrequency ablation. After the catheter enters the heart, the electrical signal is first mapped to determine the abnormal pathway or abnormal electrical excitation point, and then these abnormal electrical signal pathways are ablated and isolated, so as to achieve the purpose of treatment. [0003] Atrial fibrillation is a common arrhythmia in which the myocardium loses its normal and regular diastolic movement and replaces it with rapid and uncoordinated weak peristalsis, thereby causing the atrium to lose its normal contraction. In 1997, Profes...
