Patent ID: 7566336

Claim:
An occlusion device for occluding a left atrial appendage, the occlusion device comprising: a center post having a proximal end and a distal end; a plurality of ribs extending radially outward from the proximal end of the center post to the distal end of the center post to form a frame, wherein a diameter of the frame near the proximal end of the center post is greater than a diameter of the frame near the distal end of the center post and is shaped to securely fit within a left atrial appendage; and a PVA foam sheet attached to the ribs, the sheet extending between the ribs and forming a sack shaped barrier supported by the ribs that is closed at the proximal end and extends toward the distal end a distance sufficient to close an entrance to the left atrial appendage and to prevent blood from entering or exiting the left atrial appendage.
