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.

Abstract: An occlusion device (e.g., for treatment of the left atrial appendage) includes a framework and a biocompatible covering disposed over at least a part of the framework. The framework may include a proximal portion, a middle portion, and a distal portion, wherein: the proximal portion includes a first hub that has a fixed first diameter; the middle portion has a second diameter and includes a plurality of beams extending from the first hub to a distal portion, wherein each of the plurality of beams is connected to an adjacent beam by a first circumferentially extending column of strut pairs; and the distal portion has a third diameter. In one or more embodiments, the framework includes improved circumferential strength and minimizes foreshortening.

Abstract: An occlusive medical implant for implantation within a left atrial appendage may include an expandable framework configured to self-expand from a collapsed configuration to an expanded configuration, and an occlusive element disposed on a proximal portion of the expandable framework. At least a portion of the expandable framework may be mechanically expandable from the expanded configuration to a securement configuration. When the occlusive medical implant is disposed within the left atrial appendage, the expandable framework exerts a first radial force on the left atrial appendage in the expanded configuration and the expandable framework exerts a second radial force on the left atrial appendage in the securement configuration. The second radial force is greater than the first radial force.
