- a second shape memory process is performed by heating the second spiral body.
- a shape having a flat cross-sectional shape is stored in the second spiral body, and a medical linear member having a flat cross-sectional shape can be obtained.
- the heating for the second shape memory treatment can be performed simultaneously with the compression of the first spiral body, but is performed after the first spiral body is compressed to form the second spiral body. Thereby, the stress with respect to the obtained medical linear member can be reduced.
- the first spiral body having a perfectly circular cross-sectional shape formed by spirally winding a basic body in which a plurality of wires are arranged around a winding core is compressed into a second shape. Therefore, a medical linear member having a flat cross-sectional shape can be manufactured without being worn by braiding.
- the medical linear member obtained as described above is further cut into a second predetermined length.
- the second predetermined length is, for example, a length at which the medical linear member is used for actual treatment, and in this way, the medical wire obtained by the manufacturing method of the present invention.
- the shaped member can be easily used for treatment.
- the compression of the first spiral is performed by placing the first spiral heated by the first shape memory process on the base while being heated, and from above. This is preferably performed by pressing the compression member.
- the first spiral body cut to the first predetermined length remains in a heated state, and thus is easily deformed, and the compression can be easily performed.
- the compression member is pressed by a spring member that urges the compression member in the direction of the first spiral body.
- the pressing of the compression member can be performed by hydraulic pressure or the like, but when the first spiral body is heated, there is a risk that the device for hydraulic pressure may be damaged by heat. Accordingly, the compression member can be pressed without being damaged by heat.
- the flowchart which shows the manufacturing process of the medical linear member of this invention.

- a heating furnace not shown
- a spiral winding shape having an interval S in the arrangement direction is stored in the first spiral body 1 as described above.
- the first spiral body 1 is taken out from the heating furnace, cooled, and then cut into a length of 3 to 100 cm, for example, a length of 30 cm, in STEP 3 in FIG.
- the wick 4 is removed.
- a basic body 3 in which a plurality of wires 2 are arranged in parallel to each other is spirally wound with an interval S in the arrangement direction, and a first space portion 5 is provided inside. 1 helical body 1 is obtained.
- the first spiral body 1 has a perfect circular shape in cross section.
- the first spiral body 1 is compressed in the diameter direction of the perfect circle.
- the first helical body 1 is compressed using a compression jig 11 shown in FIG.
- the compression jig 11 includes a slide bar 14 provided between the base 12 and the top plate 13, and a plate-like press member 15 provided so as to slide up and down along the slide bar 14. ing.
