Claim Text:
1. A method of producing catheter tubes each possessing a distal end portion and a proximal end portion at which is fixed a hub, the method comprising: forming a tubular body on a core rod, the tubular body possessing an axial extent; attaching a plurality of cylindrically shaped proximal end connecting parts to a radially outer side of the tubular body; so that the cylindrically shaped proximal end connecting parts are axially spaced apart from one another along the axial extent of the tubular body; severing the core rod and the tubular body at a plurality of axially spaced apart locations after attaching the cylindrically shaped proximal end connecting part to the radially outer side of the tubular body to sever the core rod with the tubular body into a plurality of separated sections which each include a portion of the core rod covered by a portion of the tubular body and one of the proximal end connecting parts attached to the radially outer side of the portion of the tubular body; and removing the core rod from each of the sections to result in the catheter tubes in which the proximal end connecting part is the hub which is fixed to the proximal end portion of the catheter tube.
