Atrial appendage occlusion and arrhythmia treatment

An implantable cardiac orifice occlusion device comprising:

• a self-expanding proximal anchoring element comprising a generally annularly-shaped component with a frame extending across the face adapted to be deployed in the left atrium and to provide outwardly directed expansion force to anchor the device in place adjacent the ostium of the left atrial appendage (LAA);
• a proximal barrier element coupled to the proximal anchoring element and the frame and adapted to cover the left atrial appendage when implanted and adapted to act as a primary barrier to prevent blood flow into the LAA;
• a distal anchoring element comprising a generally annularly-shaped component adapted to be deployed in the LAA and adapted to secure the device in place;
• a distal barrier element coupled to the distal anchoring element and adapted to act as a secondary barrier to prevent blood flow into the LAA;
• and
• a plurality of struts having a first end coupled to the distal anchoring element and a second end coupled to the proximal anchoring element.

• a proximal barrier element coupled to the proximal anchoring element and adapted to cover the left atrial appendage when implanted, the proximal barrier element is adapted to act as a filter and allow some blood components to flow into and out of the LAA but prevent clots from flowing from the LAA into the LA;
• a distal anchoring element comprising a generally annularly-shaped component adapted to be deployed in the LAA and adapted to secure the device in place;
• a distal barrier element coupled to the distal anchoring element and adapted to act as a secondary barrier to prevent blood flow into the LAA;
