Abstract
The embodiments of the present invention provide a device that modifies the left atrial appendage (LAA) to reduce the likelihood of thrombus formation therein. The device includes a liner that reduces the volume of the LAA and remodels the interior geometry and surfaces of the LAA thereby minimizing the crenellations in the LAA that impede blood flow. According to some embodiments, the device further includes an anchor component. The anchor component helps to expand the liner upon deployment of the device in-vivo and further prevents dislodgement and migration of the device, by ensuring the device is properly seated and completely sealed against the walls and ostium of the LAA.
