Claim:
1. An occlusion device comprising a holder and a braiding comprising a plurality of thin wires or threads, said braiding having been given a suitable form in a molding and heat treatment procedure, having a proximal retention area, a distal retention area, and a cylindrical crosspiece interposed between said proximal and distal retention areas, wherein the ends of each of the wires or threads converge into the holder in the distal retention area, each thread or wire originating in the distal retention area and extending to the proximal retention area before returning to the distal retention area; wherein the two retention areas are positionable on either side of a shunt to be occluded in a septum usually by way of an intravascular surgical procedure while said crosspiece connects the proximal and distal retention areas, and wherein the proximal retention area consists of braiding free of discontinuities or ends that results in a closed proximal wall having a continuous braided surface at the proximal end of the occlusion device.
