It is a design, the material, and the production method of substitution of a guide wire. Some enforcement forms relate to the compound guide wire equipped with the connector (18) suited and constituted so that a rear anchor zone (14) and a tip zone (16), and a rear anchor zone (14) may be everlastingly joined to a tip zone (16). In some enforcement forms, at least one zone (16) is formed from the alignment elastic nickel titanium alloy.
