Abstract: A device for occluding a patient's left atrial appendage (LAA) device includes a self-expanding closure disc and an anchor. The self-expanding closure disc has an atrial side, an appendage side, and a peripheral edge configured to engage tissue on both an atrial side and an appendage side of an opening between the left atrium and the left atrial appendage. The self-expanding anchor extends from the appendage side of the self-expanding closure disc, and an annular sealing skirt extends about at least a portion of the appendage side of the self-expanding closure disc. the annular sealing skirt is more compliant than the self-expanding closure disc to seal over the left appendage side of the opening after implantation of the device in the LAA.

Abstract: The present invention relates to a medical implantable interatrial septal defect occlusion device to occlude the congenital cardiac malformations such as Atrial Septal Defect (ASD) and Patent Foramen Ovale (PFO) providing hemodynamics between two atria. The occlusion device includes distal and proximal discs having expandable shape memory characteristics, pre-created sealed potential fenestrations which are sealed with biocompatible polymeric patch and sutures to be perforated and used for any possible intervention needed.
