Abstract: The present invention relates to a mold for manufacturing a metal stent and a metal stent manufacturing method using the same and, more specifically, to a mold for manufacturing a metal stent capable of being thinly manufactured in a stent of a metal material and to a metal stent manufacturing method using the same. The mold for manufacturing a metal stent of the present invention includes: a central jig of a conductive material; and a molding part which surrounds the central jig and is formed in an engraved groove which corresponds to a stent shape in the outer circumference surface, wherein the molding part is formed with a water soluble material which is melted by water. The metal stent manufacturing method of the present invention includes: a mold forming step of forming the mold by mounting the molding part of a water soluble material on the central jig of a conductive material; an engraved groove processing step of forming an engraved groove which corresponds to a stent shape on the outer circumference surface of the molding part; an electroplating step of putting the mold in a water tank which accommodates metal electrolyte and fills the engraved groove with metal by connecting the central jig with a cathode; a mold separating step of separating the stent which is formed in metal filled in the engraved groove from the molding part by removing the molding part by dissolving the molding part in water; and a polishing step of polishing the stent.

Abstract: The present invention relates to a method for manufacturing a mold for manufacturing a metal stent, and more particularly, to a method for manufacturing a mold for manufacturing a metal stent, capable of thinly manufacturing a stent made of metal. The method for manufacturing a mold for manufacturing a metal stent comprises: an outer mold preparation step for preparing for an outer mold part in a hollow pillar shape having a first hollow part formed at the center thereof and embossed projections in a stent shape are formed on the inner circumference surface thereof; an inner mold preparation step for preparing for an inner mold part in a pillar shape made of metal having an external diameter smaller than an inner diameter of the outer mold part; an arrangement step for arranging by inserting the inner mold part into a first hollow part of the outer mold part such that at least some parts of the inner circumference surface of the outer mold part and the outer circumference surface of the inner mold part are distanced from each other so as to form a distanced part; an injection step for injection water-soluble material solved in water in the distanced part; a drying step for forming a molding part by drying the water-soluble material; and an outer mold removal step for removing the outer mold part so as to form an engraved groove in a stent shape on the outer circumference surface of the molding part by the embossed projections.
