Abstract:
The present invention relates to a stent with an improved anti-slip function and, more particularly, to a stent for expanding an occluded lesion in a lumen of a body, comprising a cylindrical stent which has a plurality of space portions by weaving or crisscrossing a wire made of a super-elastic shape memory alloy in a hollow cylindrical mesh shape and a plurality of bent portions formed at both ends thereof in a circumferential direction and is heat treated, wherein the cylindrical stent forms a first artificial blood vessel layer, made of a PTFE material, which is in close contact with the inner surface thereof, and forms a plurality of second artificial blood vessel layers, made of a PTFE material, which are in close contact with a part of the outer surface thereof at a predetermined interval, and wherein a first artificial blood vessel layer and the plurality of second artificial blood vessel layers are heat-fused so as to be fused to each other while surrounding the cylindrical stent, thereby forming a plurality of first sections having a plurality of obstructed space portions and a plurality of second sections having a plurality of remaining unobstructed space portions, each of the plurality of first sections is inserted into and is caught by the pressing of a lesion site, and each of the plurality of second sections is caught by a lesion site inserted into the space portion.
