Abstract
The stent of the present invention comprises two or more wires which are rotated and coiled in the spiral shape and are extended and braided in the longitudinal direction thereof. The wire is densely braided in the center part of the stent so that the density of wire in the center part of the stent can be greater than that at both ends of the stent. The density of wire changes continuously between both ends of the stent and the center part thereof. Additionally, the stent of the present invention comprises a plurality of wires which are rotated and coiled in the spiral shape and are extended and braided in the longitudinal direction thereof, wherein there are two or more wires and a core portion formed from radiopaque substances is inserted in the center of each wire.
