Embodiment Construction

[0082] In the present invention, the abbreviation used:

[0083] PTFE refers to polytetrafluoroethylene, namely Polytetrafluoroethylene;

[0084] FEP refers to fluorinated ethylene propylene copolymer, that is, Fluorinated ethylene propylene;

[0085] TPU refers to thermoplastic polyurethane elastomer rubber, namely Thermoplastic polyurethanes;

[0086] PET refers to polyethylene terephthalate, namely Polyethylene terephthalate;

[0087] Pebax refers to polyether block amide, namely Polyether block amide

[0088] For ease of description, the end of the device or component that is close to the user (or handle) or away from the nerve site that needs to be adjusted is called "proximal end" in the present invention, and the end of the device or component that is far away from the user (or handle) or close to The end of the neural site that needs to be modulated is called the "distal end".

[0089] The nerve in the present invention refers to the renal sympathetic nerve located...

Abstract

The invention discloses a renal artery radiofrequency ablation catheter, which includes an adjustment assembly for adjusting the nerve, the adjustment assembly includes an electrode and a bearing part for carrying the electrode, the electrode is used for transmitting adjustment energy to the nerve, the electrode includes a An electrode wire on a carrier member having a first shape in which the modulating assembly is configured to move within a blood vessel and a second shape in which the electrode is in a shape suitable for delivering modulating energy to the nerve s position. Compared with the prior art, the extension length of the electrode on the bearing part is longer, which makes the renal artery radiofrequency ablation catheter of the present invention have better ablation effect.

Description

technical field [0001] The invention relates to electrosurgery, in particular to a renal artery radiofrequency ablation catheter. Background technique [0002] Refractory hypertension, high blood pressure (sBP ≥ 160mmHg) that is difficult to control even after using 3 or more drugs (all of which have used a diuretic), is relatively common in clinical practice, with many pathogenic factors and unclear pathogenesis. The treatment effect is very poor, and the diagnosis and treatment techniques are still immature, which has become one of the major problems in the treatment of hypertension. [0003] The latest animal and clinical experimental data prove that the regulation of renal nerves (such as denervation) can significantly and permanently reduce resistant hypertension, such as the recently developed radiofrequency ablation of renal arteries. Renal artery radiofrequency ablation is an interventional technique that achieves denervation by sending an electrode catheter into a ...
