1. A method of manufacturing a connection stent, the method being configured to form cells through intersection of at least one wire while moving the wires from a starting point, as which any one reference location point is set, upward and downward so that the wire passes over protruding pins located in diagonal directions by using a jig in which detachable protruding pins are installed at all respective location points at which circumference division lines and length division lines, formed by equally dividing a circumference (VV) and length (L) of a cylinder having a diameter (R) identical to that of the body of the connection stent to be manufactured, intersect each other, the method comprising:

  • step A of forming a part of a first body by bending and moving a first wire from a first starting point at one end of the jig to a first point at a remaining end of the jig in a zigzag form;

    step B of forming a lower first head by repeating a pattern of bending the first wire in a zigzag form from the first point to a first change point at the remaining end of the jig along a circumferential surface of a lower head formation member which is fitted around a one end-side circumferential surface of the jig to protrude and in which detachable protruding pins are installed at all location points corresponding the circumference division lines on a head length division line set along one side circumference;

    step C forming a part of the first body by bending and moving the first wire from the first change point to a second point at the one end of the jig in a zigzag form; and

    step D of forming an upper first head by repeating a pattern of bending the first wire in a zigzag form from the second point to the first staring point along a circumferential surface of an upper head formation member which is fitted around an remaining end-side circumferential surface of the jig to protrude and be opposite to the lower head formation member and in which detachable protruding pins are installed at all location points corresponding the circumference division lines on a head length division line set along one side circumference.
