Abstract: A rapid exchange type medical elongated body is disclosed in which an outer diameter of a distal portion of a tubular member is set smaller than an outer diameter of a proximal portion of the tubular member, which prevents an occurrence of a kink in a physical property change region of the medical elongated body which has a relatively large change in physical property. A tubular member forming a second region of a distal member of a medical elongated body is integrally formed with a shaft portion. The distal member has a reinforcement layer containing a metallic material and formed between an inner layer and an outer layer from a first region to the second region. The reinforcement layer is disposed inside the tubular member in the second region. An outer diameter of the first region is set smaller than an outer diameter of the second region.

Abstract: A catheter manufacturing method includes positioning a shaft in a cavity of a mold. The shaft is an elongated tubular body configured to be inserted into a living body. The mold includes a first mold die and a second mold die that contact one another to define a closed space which is the cavity. The method includes injecting a molding material into the cavity from a gate at a position between the proximal end and the distal end of the shaft in the axial direction. The injecting position is offset from the center of the shaft in the transverse direction. The method includes molding a hub onto the shaft by solidifying the injected molding material in the cavity onto the outer surface of the shaft.

Abstract: A catheter is disclosed having a distal end portion of a shaft with high breaking strength even if a wall thickness of the distal end portion of the shaft is relatively small. The catheter includes an elongated tube shaped shaft. The shaft has an inner layer having a lumen along a longitudinal direction, an outer layer covering an outer peripheral side of the inner layer, and a reinforcement body disposed on the outer peripheral side of the inner layer. The outer layer has a distal outer layer on a distal end portion of the shaft, an intermediate outer layer proximal to the distal outer layer, and a proximal outer layer proximal to the intermediate outer layer. The intermediate outer layer is more flexible and thicker than the proximal outer layer, and a distal end of the reinforcement body is located proximal to a distal end of the intermediate outer layer.

Abstract: An accommodation tool is disclosed with which an operator can easily wind and accommodate a flexible medical elongated body. An accommodation tool winds and accommodates the flexible medical elongated body, for example, a guide wire. The accommodation tool has an inner wall, an outer wall, and an interlock wall. The guide wire is wound around the inner wall. The outer wall defines an accommodation space for accommodating the guide wire between the inner wall and the outer wall, and that is disposed further outward in a radial direction from a centroid of the accommodation tool than the inner wall. The interlock wall interlocks one end portion of the inner wall and one end portion of the outer wall with each other.
