A collapsing clip including a plurality of collapsed self expanding wire frame segments is contained within the distal end of a catheter. The clip can be delivered to the neck of an aneurysm within the neurovascular system using a catheter. 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.
