Abstract

一种左心耳封堵器(200)，包括密封部件(220)、位于密封部件(220)一侧的固定部件(210)、以及该连接密封部件(220)与该固定部件(210)的连接部件(230)；该密封部件(220)的径向变形能力大于该固定部件(210)的径向变形能力和/或该密封部件(220)的轴向变形能力大于该固定部件(210)的轴向变形能力。该左心耳封堵器(200)设置密封部件(220)的径向或轴向变形能力大于固定部件(210)的径向或轴向变形能力，可以避免固定部件(210)放置在左心耳(10)中后，密封部件(220)不能最佳地和左心耳(10)的口部贴合，从而增强了封堵效果；同时因密封部件(220)的变形能力较大，还可降低密封部件(220)磨损或磨破左心耳口部的风险；在保证前两点的前提下，固定部件(210)使封堵器更好地固定在左心耳(10)中，避免封堵器(200)从左心耳中脱落。
