Method of manufacturing anti-migration stent and stent manufactured thereby

An anti-migration stent constituted to prevent migration in a lumen of a human body, the anti-migration stent comprising:

• a hollow stent body formed by interweaving at least one superelastic shape memory alloy wire diagonally in such a manner that upper and lower wires alternately cross over and under each other, thereby forming a plurality of diamond-shaped spaces in the hollow stent body,
• wherein an anti-migration bent part is provided on the hollow stent body by bending the wire such that the anti-migration bent part protrudes vertically and diagonally, thereby preventing migration of the stent in the lumen of the human body.

An anti-migration stent constituted to prevent migration in a lumen of a human body, the anti-migration stent comprising:

• a hollow stent body formed by interweaving at least one superelastic shape memory alloy wire diagonally in such a manner that upper and lower wires alternately cross up and down each other, thereby forming a plurality of diamond-shaped spaces in the hollow stent body, with an expanded part provided on at least one of opposite ends of the hollow stent body by increasing a diameter of the hollow stent body,
• wherein an anti-migration bent part is provided on the expanded part by bending the wire such that the anti-migration bent part protrudes vertically and diagonally, thereby preventing migration of the stent in a lumen of a human body.

• wherein an anti-migration bent part is provided on each of the hollow stent body and the expanded part by bending the wire such that the anti-migration bent part protrudes vertically and diagonally, thereby preventing migration of the stent from the lumen of the human body.
