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.

摘要： A guidewire includes a core shaft, an outer coil body that covers an outer periphery of the core shaft, and an inner coil body that covers a distal portion of the core shaft in the outer coil body. A distal end and a proximal end of the inner coil body are free ends having no bonding portions. A bonding portion bonds the inner coil body to only one of the core shaft and the outer coil body.

摘要： A vascular stenosis model includes a stenosis region model and a transparent holding die including a groove that enables the stenosis region model to be held. The transparent holding die includes a first member and a second member that are separable from each other. In vertical sectional view of the transparent holding die, the groove is positioned at either an upper side or a lower side of a boundary between the first member and the second member.

摘要： A guidewire having high rotational torque transmissibility and high pushing torque transmissibility and having favorable restorability is provided. The guidewire has an outer coil having a tapered coil portion constituted by at least one strand wound to decrease an outer diameter toward a front end of a core shaft and an inner coil arranged inside the outer coil. An outer diameter on a front side of the inner coil arranged on a front side of the tapered coil portion is smaller than an outer diameter on a rear side of the inner coil.
