Abstract: A left atrial appendage closure (LAAC) device includes an expandable frame that is adapted to shift between a collapsed configuration and an expanded configuration, the expandable frame comprising a plurality of expandable frame struts and an occlusive member that is disposed over the expandable frame. The LAAC device includes a plurality of anchor members that are each coupled with a corresponding one of the plurality of expandable frame struts. Each of the plurality of anchor members includes an occlusive member retention region having a first occlusive member retention feature and an associated second occlusive member retention feature.

Abstract: An implantable medical device such as but not limited to a left atrial appendage closure (LAAC) device includes an expandable frame that is movable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame including a proximal portion, a distal portion and an intervening intermediate portion. The expandable frame includes a plurality of anchors extending about a periphery of the expandable frame. A primary covering extends over the proximal portion of the expandable frame and may interact with the plurality of anchors. A secondary covering extends over part of the expandable frame.
