Title
(EN) Production method for medical linear member
Abstract
(EN)

A production method for a medical linear member is provided which is not abraded upon production and which includes a flat shape in a cross section.

The method includes the steps of: forming a first spiral body (1) of an oval shape in a horizontal section by spirally winding a base body (3), in which a plurality of wires (2) formed of a shape-memory alloy is arrayed, around a winding core (4); subjecting the first spiral body (1) to first shape-memory treatment; cutting the first spiral body (1) into a first predetermined length; forming a second spiral body (5) of a flat shape in a horizontal section by compressing the first spiral body (1) in a direction along a short diameter; subjecting the second spiral body (5) to second shape-memory treatment; and removing the winding core (4) from the second spiral body (5).
