DEVICES AND METHODS FOR EXCLUDING THE LEFT ATRIAL APPENDAGE

摘要

Devices and methods for occluding the left atrial appendage (LAA) to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. A foam implant encapsulated with a tough thromboresistent membrane is placed via transvascular means into the LAA and anchored with adhesives and/or mechanical anchors. Tissue over-and in-growth are optimized to anchor the implant in place and provide a permanent occlusion.
