Abstract: A catheter according to an embodiment of the present disclosure includes a mesh member, a first hollow shaft, a front end tip, a guiding film, and a core wire. The mesh member has a tubular shape and is radially expandable and contractable. The guiding film is formed with a stretchable material and is disposed on the mesh member, the guiding film having a front end located between a base end of the front end tip and a front end of the first hollow shaft. A thickness of a base end of the guiding film is larger than a thickness of the front end of the guiding film.

The guiding film is disposed on the mesh member and has a front end located between a base end of the front end tip and a front end of the first hollow shaft. A thickness of the front end of the guiding film is larger than a thickness of a portion where a thickness of the guiding film is the smallest.

Abstract: A catheter including a mesh member having a tubular shape and being radially expandable and contractable, a first hollow shaft connected to a proximal end of the mesh member, a distal end tip, and a core wire. The first hollow shaft includes a distal end side shaft having a distal end connected to the proximal end of the mesh member and a proximal end side shaft having a distal end connected to a proximal end of the distal end side shaft. An opening is provided at the proximal end of the distal end side shaft in a connection portion between the distal end side shaft and the proximal end side shaft. A sealing member covering an outer periphery of the core wire and allowing the core wire to be slidable thereinside is arranged at the distal end of the proximal end side shaft in the connection portion.
