Abstract: 微細な線径であっても高い剛性が得られ、プッシュアビリティを向上させると共にへたりにくい、ガイドワイヤ用芯線性及びその製造方法を提供する。このガイドワイヤ用芯線(15)は、Ti−Ni系合金からなり、その線径が0.5mm以下で、ヤング率が50GPa以上とされている。そして、その製造方法は、まず、伸線ダイス(2)に素材(M0)を通して縮径させつつ所定長さに延伸させる伸線加工を施して、一次加工材(M1)を成形する。その後、スエージングダイス(5,5)で一次加工材(M1)を叩き伸ばすことにより、二次加工材(M2)が成形され、線径が0.5mm以下、ヤング率が50GPa以上の芯線(15)が製造される。

Abstract: Provided is a core wire for guide wire in which high rigidity can be attained even with a fine wire diameter so that pushability is improved while the core wire is prevented from fatigue deformation, and a method for manufacturing the core wire. This core wire 15 for guide wire is made of a Ti-Ni based alloy and has a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa. According to the manufacturing method, first, wire drawing is performed on a raw material M 0 so that the raw material M 0 is passed through a wire drawing dice 2 to be drawn to a certain length while the wire diameter of the core wire is reduced. Thus, a primary processed material M 1 is formed. After that, the primary processed material M 1 is hammered and drawn by swaging dices 5 and 5 so that a secondary processed material M 2 is formed. In this manner, the core wire 15 having a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa is manufactured.

Abstract: PROBLEM TO BE SOLVED: To provide a guide wire which is used when a tube such as a catheter is inserted in a tubular organ such as a blood vessel, and to provide its manufacturing method. SOLUTION: This guide wire 10 is equipped with a core wire 20 having a diameter-reduced section 22 on the distal end section, a coil 30 which is fitted on the outer periphery of the distal end section of the core wire 20, and a resin layer 40 which coats the outer peripheries of them. The coil 30 has a coarsely wound section 34 having a gap between wire rods on both end sections, and has a closely wound section 36 without gap between the wire rods at an intermediate section. Then, to manufacture the guide wire 10, the core wire 20A having the coil which is constituted by fixing the coil 30 to the outer periphery of the distal end section of the core wire 20 is inserted in an extrusion-molding die from the proximal end side, and the draw-molding is performed. Thus, the resin layer 40 is coated on the outer peripheries of the core wire 20 and the coil 30. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a Ti-base alloy which has superior biocompatibility and can produce excellent spring characteristics and shape memory effect and also can attain manufacturing cost reduction. SOLUTION: The Ti-base alloy consists of, by atom, 0.01 to 20% Y, 1 to 20% X1 (where X1 is one element among V, Cr, Zr, Nb, Mo, Hf and Ta or a combination of several elements among them), 0 to 20% X2 (where X2 is one element among Al, Ag and Sn or a combination of several elements among them), and the balance Ti with inevitable impurities. Owing to the addition of the Y in the above percentage, crystal grains of the Ti-base alloy can be refined and intercrystalline cracking and slip deformation can be suppressed. In addition, owing to the addition of the X1 element in the above percentage, β-phase of the Ti-base alloy excellent in deformability can be stabilized. In this way, the Ti-base alloy having superior spring characteristics and shape memory effect can be obtained. COPYRIGHT: (C)2009,JPO&INPIT
