SELF-GUIDING TYPE MEDICAL VASCULAR CATHETER ABSTRACT OF THE DISCLOSURE Disclosed is a self-guiding type medical vascular catheter made of a synthetic resin hollow monofilament. The catheter is comprised of a tip part, a relatively flexible part having a smaller diameter than the other parts, a tapering part and a manipulating part, these four parts continuously forming a line, in that order, along the monofilament axis. At least the tip part and the manipulating part have X-ray impermeable metal inserted in the respective hollows thereof. The X-ray impermeable metal has a diameter smaller than that of the hollow at least in the manipulating part so that there is formed a space within the hollow, which space defines a lumen for permitting a liquid and/or a gas to pass therethrough. The lumen is opened to the outside of the monofilament body through an inlet opening at the distal end of the manipulating part and through an outlet opening bored in the tip part, the relatively flexible part, the tapering part, or the other end of the manipulating part or in close proximity thereto.
