Title: MEDICAL LONGITUDINAL BODY AND MEDICAL INSTRUMENT SET
Abstract:
[Problem] To provide a rapid-exchange medical longitudinal body comprising a tube member of which a distal end portion is formed with an outer diameter smaller than that of a proximal end portion of the tube member, the medical longitudinal body preventing the occurrence of a kink in a physical property change region that experiences a relatively large change in physical property, and having radiopacity in the vicinity of the proximal end portion of the tube member which is preferably increased by means of a simple configuration, and to provide a medical instrument set provided with the medical longitudinal body and a catheter. [Solution] A tube member 150 forming a second region 120B of a distal end member 120 of a medical longitudinal body 100 is integrally configured with a shaft portion 110. The distal end member includes a metal material-containing reinforcement layer 160 extending from a first region 120A to the second region and formed between an inner layer 130 and an outer layer 140. The reinforcement layer in the second region is disposed on the inner side of the tube member. The first region has an outer diameter smaller than an outer diameter of the second region.
