PERIPHERAL VASCULAR STENT AND PREPARTION METHOD THEREOF AND APPLICATION THEREOF

The peripheral vascular stent comprises scaffolding holding units and a membrane, each scaffolding holding units is formed of a closed ring shape wire; the membrane is covered on scaffolding holding units, the flexibility of the membrane is greater than that of the scaffolding holding units, between the wires of the same scaffolding holding unit and/or between two adjacent scaffolding holding units is provided a plurality of hollowed-out areas on the membrane, and two adjacent scaffolding holding units are only connected by the membrane beyond the hollowed-out areas. The peripheral vessel stent can meet the mechanical performance requirements, has a proper radial support force and good flexibility, and can well reduce the in-stent chronic external expansion force, has the advantages of little impact on blood flow, little injury to the vascular wall, and less likely to cause secondary thrombosis.
