Claim 5:
6. A self expanding flow diversion device with enhanced kink resistance and radial strength employed in an arterial lumen, the device comprising;
a plurality of cells, each cell bounded by four thick wires (201, 202, 207, 208) and comprising fine wires braided together to form a fine braid, wherein a tubular device is formed by repeating the plurality of cells in axial as well as circumferential directions;
each cell characterized in that,
upper bounds of the cell formed by two thick wires (201, 202), of the four thick wires (201, 202, 207, 208), wherein an entire length of each of the two thick wires is disposed above the fine wires (groups 205, 203), and lower bounds of the cell formed by a remaining two thick wires (207, 208), of the four thick wires (201, 202, 207, 208), wherein an entire length of each of the remaining two thick wires is disposed below the fine wires (groups 204, 206), such that the two thick wires (201, 202) and the remaining two thick wires (207, 208) each, respectively, form a continuous zig-zag circumferential ring around a circumference of the self expanding flow diversion device, thereby forming a ring pattern along a length of the self expanding flow diversion device,
wherein, the self-expanding flow diversion device having the ring pattern enhances the kink resistance and radial strength.
