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.
