Abstract
Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes an occlusion member and may also include a stabilizing member. The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue in-growth onto the occlusion member. Methods are also disclosed.

10. A membrane for blocking an atrial appendage ostium comprising:
-
a membrane; and
a means for blocking the ostium of the atrial appendage with the membrane such that no blood enters the atrial appendage to form a thrombus and no thrombus escapes the atrial appendage.

43. A membrane structure for blocking an atrial appendage ostium, said atrial appendage having a wall, said membrane structure comprising:
-
a membrane; and
a plurality of prongs extending substantially outwardly from adjacent an edge of the membrane for extending into the atrial appendage through the ostium and piercing the wall of the atrial appendage substantially adjacent the ostium to secure the membrane in place;
thereby blocking the ostium of the atrial appendage with the membrane such that no blood enters the atrial appendage to form a thrombus and no thrombus escapes the atrial appendage.

64. A membrane structure for obstructing an opening in the body of a patient, said membrane comprising:
-
a membrane adapted to be lodged against the opening;
prongs adjacent an edge of the membrane extending substantially outwardly for attaching the membrane to body tissue on the opposite side of the opening from the membrane substantially adjacent the opening for securing the membrane over the opening; and
a catheter for minimally invasively inserting the membrane over the opening to block the opening.

68. Apparatus for filtering blood flowing between an atrial appendage and an atrium of a patient comprising:
-
a filter membrane adapted to be positioned across an ostium of the atrial appendage configured to allow blood flow while preventing thrombus from flowing between the atrial appendage and the atrium; and
a support structure attached to the filter having a plurality of prongs extending substantially outwardly from adjacent an edge of the filter membrane for extending into the atrial appendage through the ostium and piercing the wall of the atrial appendage substantially adjacent the ostium to secure the filter membrane in position across the ostium of the atrial appendage.

82. A device for blocking an atrial appendage opening, said atrial appendage having a wall, the device comprising:
-
a barrier; and
a plurality of barbs configured to engage tissue of an inside surface of the atrial appendage to dispose the barrier adjacent the opening of the atrial appendage. - View Dependent Claims (83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105)

106. Apparatus for acting as a barrier to embolic material or fluids between an atrial appendage and an atrium of a patient comprising:
-
a mesh adapted to be positioned adjacent an opening of the atrial appendage configured to prevent embolic material from flowing between the atrial appendage and the atrium; and
a support structure attached to the mesh having a plurality of barbs for extending into the atrial appendage and engaging a wall of the atrial appendage to secure the mesh in position adjacent the opening of the atrial appendage. - View Dependent Claims (107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118)
