Left auricle ablation plugging device

Abstract

The invention provides a left auricle ablation plugging device which comprises a supporting framework and an ablation piece arranged on the peripheral face of the supporting framework, a guide piece is arranged at the far end of the supporting framework, a connecting piece is arranged between the far end of the supporting framework and the guide piece, the connecting piece can swing relative to the axis of the supporting framework, and the left atrial appendage ablation plugging device comprises a left atrial appendage and a right atrial appendage. The guiding piece drives the connecting piece to bend until the ablation piece is attached to the proper position of the inner wall of the left auricle, the ablation piece is connected with an ablation energy source, and the ablation piece conducts annular ablation on the inner wall of the left auricle.

Description

technical field [0001] The invention relates to the technical field of interventional medical devices, in particular to a left atrial appendage ablation and occlusion device. 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 closely related to diseases such as coronary heart disease, hypertension and heart failure. [0003] The left atrial appendage (LAA) is a small muscle pouch extending from the anterolateral wall of the left atrium of the heart. Because of its special shape and structure, it is not only the most important sit...

AI Technical Summary

Problems solved by technology

[0005] The current LAA occluder with ablation function cannot adjust the position of the LAA ablation occluder according to the different shapes and sizes of the LAA, so it is difficult to control the position and effect of ablation

In addition, the inner wall of the left atrial appendage is rich in thick comb muscles and muscle trabeculae, and the anatomical shape is complex. Therefore, it is difficult for the current left atrial appendage ablation device to ensure that the left atrial appendage occluder is stably occluded in the best position after release.
