A collapsing clip including of a plurality of collapsed self expanding wire frame segments is contained within the distal end of a catheter. The clip can be maneuvered by a wire traversing through the catheter. The catheter can be placed proximate to the neck of an aneurysm within the neurovascular system. Using the wire, at least one segment can be pushed from the catheter through the aneurysm neck and expanded within the interior of the aneurysm. The wire can pull the expanded segment in a proximal direction. A proximal segment can be pushed from the catheter and expanded on the proximal side of the aneurysm. The collapsing clip impinges the distal and proximal framed wire segments onto the neck of the aneurysm. The framed wire segments are inter positioned so that the diamond shaped spaces between the wires are substantially blocked. The neck of the aneurysm is blocked by the distal and proximal framed wire segments forming a barrier.
