摘要： A guidewire includes a core shaft having front and rear sections including a front end portion and a rear section, respectively, an outer coil body that covers the front section, and an inner coil body that is disposed within the outer coil body between the outer coil body and the core shaft, and covers the front section. The outer coil body includes a cylindrical large-diameter section positioned adjacent the rear end portion, a cylindrical small-diameter section positioned adjacent the front end portion, and a tapered section that connects the cylindrical large-diameter section to the cylindrical small-diameter section with a connecting portion provided therebetween, the tapered section having a diameter that decreases from an end adjacent the rear end portion to an end adjacent the front end portion. The inner coil body is disposed at least in the tapered section.

摘要： A guidewire includes a core shaft, an outer coiled body covering at least a portion of the core shaft, and an inner coiled body positioned between the outer coiled body and the core shaft. The inner coiled body covers the at least a portion of the core shaft and a resin material is filled between the inner coiled body and one of the outer coiled body and the core shaft to form a resin layer. Preferably, a space between the inner coiled body and the other of the outer coiled body and the core shaft is not filled with the resin material.

摘要： A guidewire includes a core shaft, a coil body, and a tip portion. The coil body covers a distal end portion of the core shaft. The tip portion is formed by coupling a distal end of the coil body and a distal end of the core shaft using metal solder. The tip portion includes an outside diameter decreasing portion and a hemisphere-shaped portion. The outside diameter of the outside diameter decreasing portion decreases linearly in a direction of a distal end. The hemisphere-shaped portion is positioned at a distal end of the outside diameter decreasing portion.

摘要： There is provided a medical guidewire, which is capable of reducing the sliding resistance generated in the case of pulling the medical guidewire inside a catheter, a tubular organ or an intracorporeal tissue, and thus has favorable manipulability for a physician who performs an operation. An area between a proximal end portion of a coiled body and a core shaft is formed in streamlined shape. It is thus possible to reduce the sliding resistance generated in the case of pulling the medical guidewire inside the catheter, the tubular organ or the intracorporeal tissue. Hence it is possible to provide the medical guidewire with favorable manipulability for the physician who performs the operation. It is to be noted that the streamlined shape is preferably formed by use of a brazing material that joins the proximal end portion of the coiled body with the core shaft.
摘要翻译：提供了一种能够降低在导管，管状器官或体内组织内拉动医疗导线的情况下产生的滑动阻力的医疗用导线，因此对于进行手术的医师具有良好的操作性。螺旋体的基端部与芯轴之间的区域形成为流线形状。因此，可以减少在导管，管状器官或体内组织内拉动医疗用导丝的情况下产生的滑动阻力。因此，可以为执行操作的医师提供有利的操纵性的医疗导线。应当注意，流线型的形状优选地通过使用将线圈体的基端部与芯轴连接的钎焊材料形成。

摘要： There is provided a medical guidewire which reduces the resistance with a curved guiding catheter, and has improved durability that can keep the resistance reduced for a long time. A core shaft of the medical guidewire has a second cylindrical part, with a smaller diameter than that of a coiled body, on a proximal end side of the coiled body. This second cylindrical part is coated with a hydrophilic material. Further, the hydrophilic material coated on the second cylindrical part has a larger thickness than a hydrophilic material coated on the coiled body.
