Problems solved by technology

Since the pulmonary vein ostium has no anatomical structure that can be used to fix the head of the ablation catheter, it is easy to shift during the ablation process and affect the ablation effect
In addition, the ablation of atrial fibrillation requires a dot-line shape to achieve effective electri

Embodiment Construction

[0012] The introducer is connected with a dedicated delivery catheter, and the pulmonary vein electrical signal recorded by the introducer is transmitted to the cardiac electrophysiological recording instrument outside the body through the multi-core wire in the dedicated delivery catheter. During delivery, the introducer can be deformed into a cable-like shape and delivered to the left atrium through the delivery sheath. When reaching the predetermined position of the left atrium pulmonary vein orifice, the introducer will protrude from the delivery sheath and restore the predetermined shape to fit with the pulmonary vein orifice. Due to the good elasticity of the introducer, it can be well attached to the inner wall of pulmonary veins of different sizes and shapes. combine. The extracorporeal cardiac electrophysiological recording device will record the electrocardiographic signals in the pulmonary veins. The edge of the atrium of the introducer and the inner wall of the at...

Abstract

The invention relates to a cardiovascular surgery tool used to mark and test the electrocardiosignal of left lung vein and guide fusion duct to the fusion part, wherein it uses shape memory alloy to weave fusion guider support, lung vein mark electrode, electrode connecting line, and transmission duct. The invention can confirm better deformation and return preset shape at lung vein. It can mark electrocardiosignal in lung vein, therefore, its heart edge and inner wall can form space to guide fusion duct, to improve surgery success.

Description

Technical field [0001] The patent of the present invention relates to a cardiovascular interventional surgical instrument used in atrial fibrillation catheter ablation for mapping the ECG signal of the left atrial pulmonary vein ostium and guiding the ablation position of the head of the ablation catheter. Background technique [0002] The treatment of atrial fibrillation is a worldwide medical problem. After decades of research, there is still no breakthrough. Studies in recent years have found that pulmonary veins may be closely related to the occurrence of atrial fibrillation. According to this research result, in recent years clinical attempts to perform catheter ablation of the left atrium pulmonary vein ostium have achieved certain results, and the effective rate is about 70% to 80%. In the existing ablation of atrial fibrillation, a ring-shaped mapping electrode is usually placed at the ostium of the pulmonary vein, and then an ablation catheter is used to ablate nea...
