<p>A flexible self-expandable stent using shape memory alloy for expanding stenosal portions and method and apparatus for fabricating the same is disclosed. The self-expandable stent using shape memory alloy, comprising: a first cylindrical stent member comprised of a first wire formed of super elastic shape memory alloy and being bent a large number of times while being extended upwardly and downwardly a large number of times to form a plurality of variable rhombic spaces; and a second cylindrical stent member comprised of a second wire formed of super elastic shape memory alloy diagonally extended in parallel with the previously positioned first wire and passed alternately under and over the first wire to divide each of a plurality of rhombic spaces formed in the first cylindrical stent member into four equal parts, thereby preventing the first and second cylindrical stent members from being separated from each other.</p> |
