Patent number: 9295814Abstract: A guide wire includes a first wire disposed on the distal side, and a second wire disposed on the proximal side and made from a material having an elastic modulus larger than that of the first wire. The first wire and the second wire are joined to each other by welding. The second wire has, in the vicinity of the welded portion, a small cross-sectional area portion having a cross-sectional area smaller than that of a proximal end portion of the first wire. The outer diameter of the small cross-sectional area portion is gradually reduced in the direction toward the distal end. The first wire may be made from a superelastic alloy, whereas the second wire may be made from a stainless steel. The first wire and the second wire may be welded to each other by a butt resistance welding process. Since the change in rigidity of the guide wire becomes smooth in the longitudinal direction, the operationality and kink resistance of the guide wire are improved.Type: GrantFiled: March 7, 2014Date of Patent: March 29, 2016Assignee: TERUMO KABUSHIKI KAISHAInventors: Hiraku Murayama, Akihiko Umeno, Jun Iwami, Yutaka Itou, Youki Aimi
