Abstract

The invention provides an ablation plugging device which comprises a plugging piece and an energy processing system and is characterized in that the ablation plugging device further comprises a multi-electrode assembly arranged on the plugging piece, and the multi-electrode assembly is connected with the energy processing system; and the multi-electrode assembly comprises a plurality of electrode units, at least part of the electrode units are used for ablating a target tissue area, and at least part of the electrode units are used for monitoring electrophysiological signals of the target tissue area.

Description

technical field [0001] The present invention relates to the technical field of interventional medical devices, and relates to an ablation and occlusion device for occlusion and ablation of the left atrial appendage. The ablation and occlusion device uses percutaneous puncture to transport it to the position of the left atrial appendage of the heart through a delivery sheath , to ablate the energy transmitted by the left atrial appendage, receive physiological signals and block. Background technique [0002] Atrial fibrillation (abbreviated as atrial fibrillation) is the most common sustained arrhythmia, and with age, the incidence of atrial fibrillation continues to increase, reaching 10% in people over 75 years old. During atrial fibrillation, the frequency of atrial excitement reaches 300-600 beats / min, and the heartbeat frequency is often fast and irregular, sometimes up to 100-160 beats / min. Effective retraction function. The prevalence of atrial fibrillation is also c...
