Abstract
A method of manufacturing a medical linear member includes a step of forming a first spiral body (1) whose cross-sectional shape is a substantially perfect circular shape by spirally winding a base body (3) having a plurality of arrayed wires (2) formed of a shape memory alloy, around a winding core (4), a step of performing a first shape memory process on the first spiral body (1), a step of cutting the first spiral body (1) into a first predetermined length, a step of removing the winding core (4) from the cut first spiral body (1), a step of forming a second spiral body (6) whose cross-sectional shape is a flat shape by compressing the first spiral body (1) in a diametral direction, and a step of performing a second shape memory process on the second spiral body (6).
