STENT, STENT PRECURSOR PRODUCTION DEVICE, AND STENT PRODUCTION METHOD

In this stent, two superelastic fine wires are disposed along the axial direction at a prescribed helical pitch so as to have a prescribed stent inner diameter D0, while a pair is formed between two helical fine wires that are disposed across a micro gap of a size not more than five times the wire diameter of the fine wires in such a manner as to include a mutually contacting state. A prescribed reticulation gap is formed by crossing a clockwise-wound helical fine wire pair and a counterclockwise-wound helical fine wire pair in a plain-woven fashion, so as to have an axial gap equal to [(prescribed helical pitch)−{2×(fine wire diameter)}−(micro gap)] and a circumferential gap equal to [{(stent inner circumferential length corresponding to stent inner diameter)/N}−{2×(fine wire diameter)}−(micro gap
