Beschreibung
Zusammenfassung:	The stent is of a self-expandable tubular grid structure, the two ends of the tubular grid structure are open, the stent comprises a plurality of connected first grid units, each first grid unit comprises a plurality of side rods, and the first grid units are arranged in the direction from the middles of the side rods to the two ends of the side rods. And the sectional area of the side rod is gradually increased. The section area of the side rod of the first grid unit is gradually increased in the direction from the middle to the two ends, so that the rigidity of the side rod is gradually increased in the direction from the middle to the two ends, the dependent variables of the end of the side rod and the area close to the end are reduced, stress and strain are evenly distributed when the support deforms, and the stability of the support is improved. Stress strain concentration in a local area is avoided, deformation of the support is avoided, the size is prevented from being affected, and the rebound resilie
