Left atrial appendage occlusion and ablation apparatus

A left atrial appendage occlusion and ablation apparatus, comprising a seal (1100) located at the proximal end of the apparatus and used for closing the left atrial appendage, and an anchor (1300) located at the distal end of the apparatus and used for anchoring the apparatus in the left atrial appendage. The apparatus further comprises an ablation member (1200) used for annularly ablating the inner wall of the left atrial appendage. The left atrial appendage occlusion and ablation apparatus can achieve ablation of atrial fibrillation and stroke prevention.
