Abstract: Disclosed herein is a flexible self-expandable stent using shape memory alloy for expanding stenosal portions and method and apparatus for fabricating the same. The self-expandable stent using shape memory allow, comprises a first cylindrical stent member comprised of a first wire formed of super elastic shape memory alloy, the first wire being bent a large number of times while being extended upwardly and downwardly a large number of times, so the first wire forms a plurality of variable rhombic spaces by forming a plurality of intersections for causing the first wire to be intersected with itself to resist longitudinal constriction of the first cylindrical stent member and a plurality of interlocked points for causing the first wire to be interlocked with itself at spaced positions to allow longitudinal constriction of the first cylindrical stent member; and a second cylindrical stent member comprised of a second wire formed of super elastic shape memory alloy, the second wire being diagonally extended in parallel with the previously positioned first wire and passed alternately under and over the first wire so as 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.

Abstract: PURPOSE: A method for manufacturing an expansion tool of variable condition maintaining type by using shape memory alloy and the expansion tool are provided to minimize the deformation of blood vessel and thus ensuring smooth circulation of blood by maintaining the original shape and curvature of the blood vessel around stenosis region of the human body to be expanded, regardless of the shape and length of the expansion tool. CONSTITUTION: In order to manufacture an expansion tool installed to a stenosis region of the human body for widening a passage of that region, the one ends of projection pines(120) are detachably fixed at all setting points as intersecting points between circumference dividing lines and length dividing lines of a cylindrical body having same diameter and length with the expansion tool, and the upper most projection pin assembled at the upper most end of the cylindrical body serves as a starting point along its advance direction. A first wire(10) advances up and down through the projection pins according to a predetermined bending course to define a variable diamond space in order to achieve a primary expansion tool(X). Then, a second wire(11) also advances up and down according to a predetermined bending course while passing the upper and lower ends of the first wire to divide the variable diamond space into four parts in order to achieve a secondary expansion tool(Y). The primary and secondary expansion tools are coupled to form a hollow cylindrical body(Z) that each components thereof are freely expandible and contractible, but they can't separated. Finally, the expansion tool is heated to memorize its original shape permanently.
