摘要： Provided is a guidewire effectively usable for a retrograde approach. A guidewire has a body portion, and a first tip portion and a second tip portion provided at ends of the body portion. Flexural stiffnesses of the first tip portion and the second tip portion increase in a continuous or stepwise manner from the respective tips of the first and second tip portions toward the body portion. The flexural stiffness of the first tip portion is not smaller in value than the flexural stiffness of the second tip portion in first distance ranges from the respective tips of the first and second tip portions toward the body portion. The flexural stiffness of the first tip portion is smaller in value than the flexural stiffness of the second tip portion in second distance ranges beyond the respective first distance ranges of the first and second tip portions toward the body portion.

摘要： An object of the present invention is to provide a balloon catheter integrated with a guidewire in which a stepped portion is prevented from being formed between a coil portion of the guidewire and a front end portion of the balloon catheter and thus crossability of the balloon catheter is improved. The balloon catheter includes a transition part made of resin that smoothly connects an external shape of an outer coil of a front end coil part and an external shape of a tip portion of a front side inner shaft.

摘要： An aspect of the present invention is a balloon catheter integrated with a guidewire. An object thereof is to provide a balloon catheter allowing smooth connection between a coil portion of the guidewire and a front end portion of the balloon catheter by preventing the stepped portion from being formed therebetween and allowing the tip portion of the guidewire to sufficiently exhibit characteristics thereof without providing any additional element. The balloon catheter includes: a protruding portion formed of an inner coil which is arranged inside a front end coil part and which extends from a rear end of the front end coil part to surround a core shaft; and a front end opening part of a guidewire lumen that is provided at a front end of a catheter body and into which the protruding portion is inserted.
