1. A method of manufacturing a stent, comprising:
- forming a first cylindrical mesh structure by bending a first member in a zigzag-shape having peaks and valleys and a plurality of turns wound around an outer circumference of a manufacturing frame; and
forming a second cylindrical mesh structure by bending a second member in a zigzag-shape having peaks and valleys and a plurality of turns wound around an outer circumference of a manufacturing frame, wherein a bending track the second member crosses a bending track of the first member.

6. A method of manufacturing a stent, comprising:
-
providing a plurality of pins on a cylindrical surface of a cylindrical manufacturing frame and setting one of a plurality of pins as a starting point; winding a first member around the cylindrical manufacturing frame from the starting point to an end of the cylindrical manufacturing frame while being bent in a zigzag-shape to form peaks and valley with reference to the pins and having a plurality of turns; winding the first member around the cylindrical manufacturing frame from the end of the cylindrical manufacturing frame to the starting point while being bent in a zigzag-shape to form peaks and valley with reference to the pins and having a plurality of turns, the peaks and valley are crossed and interlocked each other when the peaks and valleys meet each other; forming a strut by spirally twisting a distal end portion of the first member and a proximal end portion of the first member after the peaks and valleys of the first member are formed; winding a second member around the cylindrical manufacturing frame from a starting point to an end of the cylindrical manufacturing frame while being bent in a zigzag-shape to form peaks and valley with reference to the pins and having a plurality of turns, wherein the starting point of the second member is disposed on a symmetrically opposite location of the starting point of the first member on the surface of the cylindrical manufacturing frame; winding the second member around the cylindrical manufacturing frame from the end of the cylindrical manufacturing frame to the starting point while being bent in a zigzag-shape to form peaks and valley with reference to the pins and having a plurality of turns, the peaks and valley are crossed and interlocked each other when the peaks and valleys meet each other; and forming a strut by spirally twisting a distal end portion of the second member and a proximal end portion of the first member after the peaks and valleys of the first member are formed.

7. A stent comprising:
-
a first cylindrical mesh structure formed by bending a first member in a zigzag-shape having peaks and valleys and a plurality of turns wound around an outer circumference of a manufacturing frame; and a second cylindrical mesh structure formed by bending a second member in a zigzag-shape having peaks and valleys and a plurality of turns wound around an outer circumference of a manufacturing frame, wherein a bending track the second member crosses a bending track of the first member, wherein the first cylindrical mesh structure includes a first strut formed of a spirally twisted strut that is formed at a point where a distal end of the first member meets a proximal end of the first member; and
the second cylindrical mesh structure includes a second strut formed of a spirally twisted strut that is formed at a point where a distal end of the second member meets a proximal end of the second member. - View Dependent Claims (8)
