The RF energy could be transferred to the clamp, and generate heat, which can cause local myocardial coagulation and necrosis, tissue degeneration. The lesions responsible for atrial fibrillation could be isolated without compromising the normal surrounding tissue. Thus, ectopic pacing triggers would be isolated and the fast ectopic impulse conduction would be blocked. By interrupting the macro-reentry, the reason for atrial fibrillation would be eliminated. Then the atrial fibrillation is cured. Surgical radiofrequency ablation is one of the best methods for persistent atrial fibrillation tre...

Cardiogenic stroke is one of the most serious complications of atrial fibrillation. This kind of clip mechanically close left atrial appendage, and block thrombi generated from LAA. For the patient with ectopic pacemaker from LAA, the clip can also play a role for electrical isolation. The LAA clip can be used together with surgical treatment for AF or stand alone. Its simplicity, safety and effectiveness have been proved with high success rate. Stroke and LAAStroke is one of the top 3 killers that endanger human health. It has high incidence, high morbidity and high mortality. Atrial fib...
