Problems solved by technology

[0005] The prior art discloses a helical ring renal artery sympathetic nerve radiofrequency ablation electrode catheter. Although the renal artery can be ablated, its diameter is fixed and cannot be adjusted. It cannot ensure that the electrode adheres to the renal artery. Without temperature monitoring measures, the ablation temperature cannot be precisely controlled, resulting in insufficient ablation or excessive ablation, resulting in renal artery perforation and affecting human health

Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Such as figure 1 As shown, the embodiment of the present invention provides a renal artery radiofrequency ablation catheter, which mainly includes an ablation electrode 1 , a catheter body 2 and a control handle 3 . One end of the catheter body 2 is Z-shaped, and its end is connected to the ablation electrode 1; the other end is connected to the control handle 3;

[0031] The end of the control handle 3 is connected to an electrical connector 4, and the renal artery radiofrequency ablation instrument is connected through the electrical connector 4.

[0032] Among them, the material of ablation electrode 1 is gold, platinum, platinum alloy or medical stainless stee...

Abstract

The invention relates to the field of active medical device intervention, in particular to a radiofrequency ablation catheter for renal arteries. The radiofrequency ablation catheter for the renal arteries comprises an ablation electrode, a catheter body and a control handle; one end of the catheter body is Z-shaped and is connected with the ablation electrode; the control handle is connected to the other end of the catheter body; an electric connector is connected with an end of the control handle, and the control handle is connected with a radiofrequency ablation instrument for the renal arteries by the electric connector. The radiofrequency ablation catheter for the renal arteries has the advantages that the radiofrequency ablation catheter is simple in structure and convenient to operate, and renal sympathetic efferent nerves of a patient can be regulated, so that the blood pressure of the patient can be actively and effectively reduced, and clinical medical service requirements can be met.

Description

technical field [0001] The invention relates to the field of active medical device intervention, and relates to a renal artery radiofrequency ablation catheter for treating obstinate hypertension. Background technique [0002] Refractory hypertension refers to the use of three or more antihypertensive drugs (including diuretics) and lifestyle changes, but the blood pressure is still greater than or equal to 140 / 90mmHg. Resistant hypertension is the most common cardiovascular disease among middle-aged and elderly people, and it is also an important risk factor for coronary heart disease, stroke, congestive heart failure, renal failure, and aortic aneurysm. reason. Therefore, timely diagnosis and prevention of resistant hypertension are of great significance to improve the quality of life of middle-aged and elderly people and ensure their health and longevity. [0003] With the increase of life expectancy in our country. The prevalence of hypertension in the elderly has rea...
