Abstract
Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. A foam implant is delivered via transcatheter delivery into the LAA and anchored using an internal locking system of the implant. The locking system includes deployable anchors that can be deployed after deployment of the foam implant from the delivery catheter and expansion of the foam within the LAA. The implant location can thus be verified before deploying the anchors to secure the implant. The locking system can be reversible to allow retraction of the anchors and repositioning or retrieval of the implant.
