Stent and Method for Manufacturing the Same

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.

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.
