Abstract
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.
Claims21
(canceled)
A left atrial appendage occlusion device, comprising:
- an expandable body having a proximal, occlusive end for facing a left atrium following implantation of the device in a left atrial appendage, a distal end for facing into the left atrial appendage following implantation of the device in the left atrial appendage, and an open cell foam sidewall;
- a self-expandable stent carried within the expandable body such that the foam sidewall provides a cushion between the stent and the left atrial appendage following implantation, the stent comprising a plurality of struts defining a plurality of apexes;
- and
- a thromboresistent covering on at least a portion of the expandable body.
