Abstract

Disclosed herein is a stent.

The stent includes: a stent body in which a plurality of band parts having circumferences formed by supporting parts arranged in a connection state having a zigzag shape are formed in a connection state in which they configure a cylindrical shape; and a spiral support part extended and formed in a spiral wound state from one end portion of the stent body in a length direction toward the other end portion of the stent body in the length direction in a state in which it configures a supporting part of any one point among supporting parts of the respective band parts.

Claims

1. A method of manufacturing a stent, comprising:

a) forming a spiral support part by banding a wire so as to have a spiral wound state from one side toward the other side; and

b) banding the wire in a state in which the spiral support part configures a portion of a circumference to form a plurality of band parts and forming a stent body so that the band parts configure a connection state having a cylindrical shape.

2. The method of manufacturing a stent of claim 1, wherein:

in the step a),

the wire is banded to have a spiral wound state configuring a circumference of the stent body from one end portion point of the stent body in a length direction toward the other end portion point of the stent body in the length direction.

3. The method of manufacturing a stent of claim 2, wherein:

in the step a),

the wire is banded to configure a wound state in which it is wound around the circumference of the stent body by one turn or more.

4. The method of manufacturing a stent of claim 2, wherein:

in the step a),

the wire is banded to have spiral support sections extended and formed integrally with each other from one end portion point of the stent body in the length direction toward the other end portion point of the stent body in the length direction.

5. The method of manufacturing a stent of claim 1, wherein:

in the step b),

the wire is banded so as to have supporting parts arranged in a connection state configuring a zigzag shape to form the band parts in a state in which the supporting parts configure the circumference of the stent together with the spiral support part.

6. The method of manufacturing a stent of claim 5, wherein:

in the step b),

a wire banding process is performed in a state in which a supporting part of any one point among the supporting parts forming circumferences of the band parts is formed by some of support sections of the spiral support part.

7. The method of manufacturing a stent of claim 5, wherein:

in the step b),

a banding process of banding the wire in the zigzag shape to form any one band part and banding the wire in the zigzag shape to have an entanglement state in which it configures a cylindrical shape together with any one band part to extend and form another band part is performed.
