Abstract

The invention provides an occluding sacculus structure. The occluding sacculus structure comprises a sacculus and a sacculus catheter. The sacculus is arranged at the front end of the sacculus catheter, the surface of the balloon is provided with a plurality of electrodes, and the sacculus catheter is provided with a passage pipeline and an electrode connecting wire bundle, wherein the passage pipeline is communicated with the sacculus and the electrode connecting wire bundle is used for connecting the electrodes correspondingly. In the occluding sacculus structure provided by the present invention, The electrode on the surface of the balloon can collect the potential change of the pulmonary vein orifice, and the sacculus can occlude the blood at the distal end of the pulmonary vein orifice, thus effectively avoiding the blood flow scouring and affecting the corresponding surgical effect, so that the pulmonary vein can be stabilized during the operation, and the success rate of the operation can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an occlusion balloon structure. Background technique [0002] Atrial fibrillation (atrial fibrillation, referred to as atrial fibrillation) is one of the most common clinical arrhythmias, and its incidence increases with age. Compared with non-atrial fibrillation patients of the same age, the quality of life of atrial fibrillation patients is often poor And it is often accompanied by diseases such as hypertension and heart failure, so its thromboembolic complications and mortality are high. In order to solve this problem, an ablation method --- cryoballoon ablation (cryoballoon ablation) began to be applied clinically. Different from traditional radiofrequency ablation, cryoballoon ablation is to block the balloon to the vestibule of the pulmonary vein, and transmit the energy of low temperature to the surrounding of the balloon, thereby causing direct or indirect da...
