Claim 0:
1. 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, wherein each thick wire has a length, each cell having four corners, and each cell comprising of a set of 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,
half the length of each thick wire (portions 101, 110, 112, 113) being disposed above the fine wires (groups 103, 105, 115, 108), and a remaining length of each thick wire (portions 102, 109, 111, 114) being disposed below the fine wires (groups 104, 107, 106, 116), such that each corner of the cell comprises an X-shaped crossing formed by two thick wires crossing one another, wherein two X-shaped crossings are formed by two thick wires which are disposed under the fine wires and two X-shaped crossings are formed by two thick wires which are disposed above the fine wires, forming a checker board pattern,
wherein, the self expanding flow diversion device having the checker board pattern enhances the kink resistance and radial strength with minimal loss in flexibility.
