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.
