Abstract:
1. A closure device for blocking blood flow into an aneurysm through a neck of the aneurysm, the closure device comprising: a frame for positioning the closure device in the neck of the aneurysm, the frame having an origin disposed along a longitudinal axis of the closure device and a plurality of wire lobes extending generally away from the origin to a distal portion wherein each wire lobe has a first arm portion, a distal portion, and a second arm portion, the first arm portion having a first proximal end and a first distal end adjoining the distal portion, the second arm portion having a second proximal end and a second distal end adjoining the distal portion, the distal portion extending from the first distal end of the first arm portion to the second distal end of the second arm portion, at least one first proximal end being directly connected to at least one second proximal end; and a cover supported by the frame, the cover being a barrier over the frame to block blood flow through the frame into the aneurysm, and having a cover body extending from the origin of the frame to the distal portions of the wire lobes, wherein the frame has a collapsed state for delivery of the closure device to the aneurysm and an expanded state for blocking blood flow into the aneurysm, the frame has an outer surface facing away from the longitudinal axis in the expanded state.
