Percutaneous coronary intervention radio frequency ablation electrode catheter

Abstract

The invention relates to a percutaneous coronary intervention radio frequency ablation electrode catheter which comprises an outer pipe, a core pipe, a handle, a core pipe handle, electrodes, guide wires and electrode plugs, wherein the core pipe is arranged in the outer pipe; the handle is fixedly connected with the near end of the outer pipe; the core pipe handle is fixedly connected with the near end of the core pipe; the guide wires are connected with the electrodes; the electrode plugs are connected with a radio frequency ablatograph; the far end of the outer pipe is provided with an electrode bearing device; the far end of the outer pipe is fixedly connected with that of the core pipe; the electrode bearing device is provided with a plurality of strips; the strips are distributed in the circumferential direction of the outer pipe and are arranged in a staggered manner in the axial direction; the electrodes are fixed at the middle parts of the strips; and when the outer pipe and the core pipe oppositely move, the electrodes on the strips are hunched up in the radial direction and are distributed in a staggered manner. The radio frequency ablation electrode catheter greatly reduces damage to renal artery and moreover, the maximum diameter of the electrode bearing device at the far end of the radio frequency ablation electrode catheter can be correspondingly regulated according to the diameter of the blood vessel of a patient.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a percutaneous radiofrequency ablation electrode catheter for treating high blood pressure by removing renal sympathetic nerves. Background technique [0002] Hypertension is a common disease that seriously affects people's quality of life and is life-threatening. It is also the main cause of death worldwide. Seven million people die from hypertension every year. On October 12, 2004, the "Investigation Report on the Nutrition and Health Status of Chinese Residents" released at the press conference of the State Council Information Office pointed out that the prevalence of hypertension among adults in my country was 18.8%, and the awareness rate, treatment rate and control rate of hypertension among the population The rates are only 30.2%, 24.7% and 6.1%. Even in the United States, the control rate of hypertension treatment in recent years is less than 30%. At present, m...

AI Technical Summary

Problems solved by technology

The patient suffers for a long time, the surgical procedure is complicated, and the doctor's operation is difficult

In the prior art, an ablation catheter for treating arrhythmia is also used to ablate the sympathetic nerve on the renal artery to achieve the purpose of treating refractory hypertension. The ablation area is larger, causing greater damage to the renal artery
