摘要： A guide wire has a coil body covered with a hydrophilic coating film that exhibits sufficient lubricity even when there is little moisture in its surroundings. In the coil-type guide wire, a coating portion is formed by a plurality of layers where the innermost layer includes a hydrophobic film and an outer layer includes a hydrophilic film. Portions of the innermost layer extend between adjacent coils of the coil body and spaces are formed between the outer layer thereof and the portions of the innermost layer between the coils. The spaces allow moisture to pool so that when moisture in the guide wire's surroundings decreases, it is possible to supply the moisture pooled in the spaces to the hydrophilic film. Thus, even when there is little moisture in the guide wire's surroundings, it is possible to have a sufficient amount of lubricity.
摘要翻译：引导线具有被亲水性涂膜覆盖的线圈体，即使在周围几乎没有水分的情况下也能显示足够的润滑性。在线圈型导丝中，涂层部分由多层构成，其中最内层包括疏水膜，外层包括亲水膜。最内层的部分在线圈体的相邻线圈之间延伸，并且在其外层和线圈之间的最内层的部分之间形成空间。这些空间允许湿气进行游泳，使得当导丝周围的水分减少时，可以将积聚在空间中的水分供应到亲水膜。因此，即使在导丝周围几乎没有水分的情况下，也可以具有足够的润滑性。

摘要： A shaft suppresses a permanent set, or plastic deformation, even when inserted into an extremely winding blood vessel. A guidewire incorporates the above shaft. The shaft is twisted along its longitudinal axis and has a cross section forming a substantially rectangular shape extending in a first direction perpendicular to the longitudinal axis. The cross section has at least one arcuate recess.

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： Provided is a guidewire including a core shaft, an outer flexible tube, and an inner flexible tube that surrounds a distal end portion of the core shaft. The inner flexible tube is disposed in the outer flexible tube so that a distal end thereof is positioned between the distal end of the core shaft and a proximal end of the core shaft so as to be separated from the core shaft. A first joint is formed so as to join the distal end of the inner flexible tube to the core shaft. At least one second joint is formed so as to join the outer flexible tube to the inner flexible tube. The at least one second joint is positioned between the first joint and the proximal end of the core shaft.

摘要： In a pusher guide wire, a protective film is suspended with respect to a core shaft with a distal end thereof being fitted in a distal-end holder and a proximal end thereof being fitted in a proximal-end holder. Hence, the frictional resistance generated between the protective film and a stent when the core shaft is rotated is reduced. Thus, the protective film is prevented from coming off the core shaft, the stent is prevented from being damaged, and the transmissibility of rotation of the pusher guide wire is improved. Consequently, the position where the stent is to be released is easily adjustable.

摘要： In a guidewire, a second curved portion has a higher flexibility than a first curved portion and a third curved portion. Thus, a portion around the second curved portion can bend to a large degree. Consequently, a distal tip of the guidewire, in a state of being stuck on a side branch, can be released from the side branch and a distal region can be prevented from being rotated around the second curved portion.
