A braided self-expanding endoluminal stent comprises a tube-shaped grid formed by connection of a plurality of wave bands along the periphery direction. Each wave band is composed of a plurality of wave crests and wave troughs of an elastic wire on the axial direction, and is respectively connected with another wave band. Two sides of each wave band are respectively provided with a wave band abutted side by side. At least one cross-linking point is arranged between every two wave bands abutted side by side. Each cross-linking point is formed by one wave trough on one of wave bands which are abutted side by side intersecting one corresponding wave crest on the other wave band, and at least one part of the cross-linking points are the fixed cross-linking points. Each wave band is also staggered and overlapped with at least another wave band, and a plurality of crossing points (12, 14, 22, 23) are formed between the wave bands which are staggered and overlapped. A group of parallel wave bands are formed by each wave band and at least another wave band. Due to the fact that the group of the wave bands are provided with similar wave shapes and in parallel with each other, the cross-linking points or crossing points (12, 14, 22, 23) can not be formed between the paralleled wave bands. |
