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.

Abstract: A low profile implant, system and method of deployment includes a frame comprising an elongate body having ends that overlap to form an annular configuration of the frame. A circumference of the frame may be modified by varying an extent of the overlap between the ends of the elongate body. The elongate structure may extend through a sleeve of a number of respective anchor housings of the implant along a first axis, and anchors may be deployed through bores in the anchor housings along a second axis to secure the anchor housings to tissue. The implant may be deployed about and anchored to a valve annulus, and the circumference of the frame, and associated anchored tissue, may be adjusted to reconfigure the valve annulus.

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 medical device also includes a plurality of spine members coupled to the expandable member, the plurality of spine members spaced circumferentially around an outer surface of the expandable member. Additionally, the medical device includes a valve member extending at least partially into the inflation cavity, wherein the plurality of spine members are configured to position the medical device within an opening of the left atrial appendage and wherein the expandable member is configured to expand and seal the opening of the left atrial appendage.
