Abstract

A medical catheter having a resin shaft composed of two sections that are a distal shaft and a proximal shaft, a metal core wire, and a resin hub. The distal shaft is constructed such that its rigidity increases from its distal end to its proximal end, and is formed in a dual lumen structure having a first lumen from the distal end to the proximal end of the distal shaft and a second lumen from a position more on the proximal end side than the distal end of the first lumen to the proximal end of the proximal end of the distal shaft. The proximal shaft is formed in a coaxial dual tube structure having, from the distal end to the proximal end of the proximal shaft, an inner tube and an outer tube. The proximal end of the second lumen of the distal shaft and the distal end of the inner tube of the proximal shaft are connected such that a guide wire can be inserted through them, and the proximal end of the outer tube of and the proximal end of the inner tube of the proximal shaft are connected to the resin hub such that the guide wire can be inserted through them. The metal core wire is placed between the inner tube and the outer tube, across the overall length of the proximal shaft, and is fixed to a resin material of the proximal end of the distal shaft and to a resin material of the distal end of the proximal shaft.
