Abstract

A catheter includes a distal shaft, and a proximal shaft having its distal portion inserted and fixed in the distal shaft. The distal shaft includes a guide wire lumen, and a distal shaft lumen, with the distal shaft lumen communicating with a proximal shaft lumen. The proximal shaft includes a main body portion, a distal portion smaller in size than the main body portion and entering into the distal shaft lumen, and a proximal shaft inclined portion located between the main body portion and the distal portion. The distal shaft lumen has a lumen change portion reduced in lumen cross-section toward the distal side. The proximal shaft inclined portion and the lumen change portion abut on each other.
