Abstract

The invention discloses an electrophysiology catheter. The electrophysiology catheter comprises a catheter bendable section, a catheter main body section and a catheter handle which are connected in sequence, wherein the far end of the catheter bendable section is provided with an annular ring, a plurality of annular electrodes are distributed on the annular ring, the catheter handle is provided with a ring adjusting push button, the catheter is internally provided with a first cavity, the first cavity is provided with ring adjusting wires in a penetrating manner, and the ring adjusting wires are respectively connected with the ring adjusting push button and the far end of the annular ring. According to the electrophysiology catheter provided by the invention, the far end of the catheter bendable section is provided with the annular ring, and the push button of the catheter handle and the ring adjusting wires arranged in the catheter are used for controlling the bending shape of the far end of the catheter and the diameter of the annular ring, so that the plurality of electrodes arranged on the far end of the catheter effectively attach to the mouth part or the inner wall of the renal artery, the purpose of treating the refractory hypertension and other cardiovascular diseases, such as atrial fibrillation and catecholaminergic polymorphic ventricular tachycardia related to sympathetic nerve excessive activation is achieved, and the operation is safe and reliable.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an electrophysiological catheter. Background technique [0002] Refractory hypertension is common in clinical practice, with many pathogenic factors, unclear pathogenesis, poor effect of drug treatment, and immature diagnosis and treatment methods, which has become one of the main problems in the treatment of hypertension, and patients with this disease are often accompanied by There are other risk factors for cardiovascular disease, such as coronary heart disease, diabetes, heart failure, kidney disease, peripheral arterial disease, stroke, left ventricular hypertrophy, etc. Among the various complications of hypertension, the damage to the heart, brain, and kidney is the most significant. For example, according to the statistics of the World Health Organization, 50% of cardiovascular diseases are caused by high blood pressure. At present, the number of deaths caused by cardiov...
