Pulse ablation device

Abstract

The invention provides a system for treating arrhythmia, which comprises a pulse signal generator configured to generate a pulse signal, a cardiac pacing synchronization processor configured to generate a pacing signal for stimulating the heart, an electrical stimulation program controller configured to cooperate with the pulse signal and the pacing signal, an ablation device configured to deliver the pulse signal and the pacing signal to ablation tissue, a display device configured to display parameters during operation of the pulse ablation system; wherein the ablation device comprises a catheter head end located on one side of the far end of the ablation device, the catheter head end comprises a telescopic woven mesh, a mapping electrode located on one side of the far end of the telescopic woven mesh and an ablation electrode located at the equator position of the telescopic woven mesh, and the telescopic woven mesh can be switched between an unfolded state and a folded state. According to the system, ablation can be achieved at the joint of the superior vena cava and the right atrium, the joint of the pulmonary vein and the left atrium and the coronary sinus, and the operation difficulty is low.

Description

technical field [0001] The invention relates to the field of cardiac ablation, in particular to a pulse ablation system for mapping and treating arrhythmia. Background technique [0002] Arrhythmia refers to any abnormality in the origin of cardiac impulses, heart rate and rhythm, and impulse conduction. The most common clinical sustained arrhythmia is atrial fibrillation (abbreviated as atrial fibrillation), which is caused by abnormal changes in the electrophysiological properties of atrial myocytes due to various pathogenic factors, causing rapid and irregular contractions of the atria and ventricles, thereby It can cause patients with uncomfortable symptoms such as palpitations, shortness of breath, and fatigue, and increase the incidence of adverse events such as heart failure, thromboembolism, and death. [0003] The incidence of atrial fibrillation is increasing year by year. As of 2010, there were an estimated 33.5 million patients with atrial fibrillation worldwide...

Problems solved by technology

The reasons for this phenomenon are as follows: 1. Irreversible electroporation causes the size of micropores in the cell membrane to be too large, which breaks the physiological balance inside and outside the cell and leads to cell death; 2. Under the action of a high-intensity narrow pulse electric field, the organelles inside the cell release Apoptotic factors that cause programmed cell death
