Abstract

The invention relates to an electrode radiofrequency ablation catheter. The electrode radiofrequency ablation catheter comprises an annular segment and a plurality of electrodes, wherein the annular segment is positioned at the far end of the catheter, a fluid perfusion passage is arranged in the annular segment, the electrodes are arranged on the annular segment at intervals, and each electrode is provided with a plurality of small holes which allow fluid to flow out and are communicated with the fluid perfusion passage through perfusion holes. The diameter of each perfusion hole corresponding to the corresponding electrode is d(n), n refers to an electrode sequence number, the smaller the distance from the electrodes to the tail end of the catheter is, the larger the n is, and d(n) increases along with increase of the n. Through the design, flow quantity difference among the perfusion holes can be decreased, so that flow of the perfusion holes tends to be even.

Description

technical field [0001] The invention relates to a catheter, in particular to an electrode radiofrequency ablation catheter. 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, Professor of Cardiology Michelle Aishagal...
