摘要： In a guide wire of the present invention, a distal end portion of a core has a distal small-diameter body and a combined truncated cone including a first truncated cone in order from a distal end side to a proximal end side. A twist angle of the distal small-diameter body is specified to be larger than the twist angle of the first truncated cone to increase flexibility for easily bending at the distal end. At least one truncated cone is connected on the proximal end side of the first truncated cone to form the structure of a combined truncated cone. Thus, the guide wire of the present invention has high rotation transmission performance toward the distal end side and other performances. Accordingly, the guide wire can be quickly reached to the vascular lesion and has high passability at the vascular lesion.

摘要： In a medical guide wire having a connecting structure formed by three members: a tubular connector; a first core; and a second core, when a torsional rigidity of one member is lower than the torsional rigidity of the materials of both end portions, for example, the twist is unevenly generated between the members and the rotation transmission performance to the distal end side is significantly reduced. In such a case, there is a technical problem for improving the rotation transmission performance to the distal end side. In the connecting structure formed by three members, as a result of focusing on the torsional rigidity of the three members and considering the torsional rigidity ratios between the members, the technical problem for improving the rotation transmission performance to the distal end side can be solved when the torsional rigidity ratios satisfy a predetermined relation.

摘要： A distal end portion 2B of the core has a structure of a combined truncated cone 26 formed by connecting truncated cones satisfying a predetermined relational expression. An outer diameter ratio between the maximum outer diameter and the minimum outer diameter of the combined truncated cone 26 is greater than the outer diameter ratio between a large diameter proximal portion and a small diameter distal portion of an inner coil 4, and is greater than the outer diameter ratio between a large diameter proximal portion and a small diameter distal portion of the outer coil. Because of this, the rotation angle of the proximal side is reduced when rotation operation is performed and the torsional moment toward the distal end side is increased. Thus, the perforation performance at the completely occluded lesion can be improved.
摘要翻译：芯的远端部分2B具有通过连接满足预定关系式的截头圆锥而形成的组合截锥26的结构。组合截锥26的最大外径与最小外径之间的外径比大于内线圈4的大直径近端部分与小直径远端部分之间的外径比，并且大于外部线圈的大直径近端部分和小直径远端部分之间的外径比。因此，当进行旋转操作并且朝向远端侧的扭矩增大时，近侧的旋转角度减小。因此，可以改善完全闭塞病变处的穿孔性能。

摘要： An outer coil (13) and an inner coil (14) are joined in parallel with a distal end portion of a core (11) of a guide wire (10). A winding direction of a strand (8) of the outer coil (13) is the same as that of a strand (9) of the inner coil (14). Diameters of the outer and inner coils (13, 14) increase or decrease when rotation of the core (11) is transmitted and thereby rotation transmission capability is improved. An outer space wound portion (13A) and an inner space wound portion (14A) are formed in corresponding positions in the outer coil (13) and the inner coil (14), respectively, in a core direction. Even if the guide wire (10) has a double-coil structure, the outer and inner space wound portions (13A, 14A) improve flexibility of the guide wire (10). A coil pitch of the outer space wound portion (13A) differs from a coil pitch of the inner space wound portion (14A). Thereby, engagement of the strands (8, 9) is prevented.
