Problems solved by technology

However, the same set of ablation catheters cannot be compatible with multiple ablation modes, and the catheter needs to be replaced frequently during the ablation process, which not only increases the operation time, but also increases the risk during the operation. In addition, the current pulse ablation catheter is not suitable for renal arteries Sympathetic denervation, which limits the use of ablation in the treatment of hypertension, affects the therapeutic effect of hypertension

Abstract

The invention relates to an electrode device, an ablation catheter and an ablation system. The ablation system comprises an energy output device and an ablation catheter, and the energy output device is used for selectively conveying ablation energy to the ablation catheter; the ablation catheter comprises a catheter body and a catheter head end, the catheter head end is connected with the far end of the catheter body, the catheter head end comprises an electrode device, the electrode device comprises a first electrode and a second electrode which are axially distributed, the first electrode is located at the head end of the electrode device, and the first electrode and the second electrode are connected through an insulating part; and therefore, the ablation catheter can achieve bipolar pulse ablation, unipolar pulse ablation and radio frequency effects, especially the ablation catheter can also be used for pulse ablation of renal arteries, and the ablation mode is more flexible and convenient.

Description

technical field [0001] The present invention relates to the technical field of medical instruments, and more specifically relates to an electrode device, an ablation catheter and an ablation system. Background technique [0002] Hypertension (HTN, the abbreviation of High Twisted Nematic) is one of the main risk factors of cardiovascular disease and a public health problem worldwide. It is estimated that more than 1 billion people worldwide suffer from high blood pressure, which is expected to increase to 1.5 billion by 2025; more than 9 million deaths per year are attributed to complications of hypertension, such as myocardial infarction, stroke, and renal failure. The existing antihypertensive treatment is entirely based on the selection and combination of various antihypertensive drugs. Although there are many safe and effective antihypertensive drugs, 10%-15% of hypertensive patients still take tolerable doses 3 or more antihypertensive drugs (including diuretics), or 4...
