摘要：
An example medical device for occluding the left atrial appendage is disclosed. The example medical device includes an expandable member including a first balloon defining a first inflation chamber and a second balloon defining a second inflation chamber. Further, the second inflation chamber is positioned adjacent to the first inflation chamber, the first inflation chamber is in fluid communication with the second inflation chamber and the expandable member is designed to shift between a first configuration and a second expanded configuration. Additionally, the first balloon is designed to fill a first region of the left atrial appendage and the second balloon is designed to fill a second region of the left atrial appendage. The medical device also includes a first inflation valve member extending at least partially into the first inflation chamber and the expandable member is configured to expand and seal the opening of the left atrial appendage.
