Abstract

An example medical device for occluding the left atrial appendage is disclosed. The example medical device for occluding the left atrial appendage includes an expandable member having a first end region, a second end region and an inflation cavity. The example medical device includes at least one fixation member having a first end and a second end coupled to the expandable member. The at least one fixation member is configured to move from a delivery configuration to a deployed configuration in response to an expansion of the expandable member. Additionally, the example medical device includes a valve member extending at least partially into the inflation cavity and the expandable member is configured to expand and seal the opening of the left atrial appendage.
