FLOW GUIDE WIRE FOR MULTIPURPOSE MEDICAL TREATMENT

摘要

Disclosed is a self-guiding type medical vascular catheter (1) made of a synthetic resin hollow monofilament. The catheter is comprised of a tip part (4), a relatively flexible part (5) having a smaller diameter than the other parts, a tapering part (6) and a manipulating part (8), these four parts continuously forming a line, in that order, along the monofilament axis. At least the tip part (4) and the manipulating part (8) have X-ray impermeable metal (9) inserted in the respective hollows thereof. The X-ray impermeable metal (9) has a diameter smaller than that of the hollow (2) in the manipulating part so that there is formed a space (2 min ) within the hollow, which space defines a lumen for permitting a liquid and/or a gas to pass therethrough. The lumen (2 min ) is opened to the outside of the monofilament body through an inlet opening (10) at the distal end of the manipulating part and through an outlet opening (7) bored in the tip part (4), the relatively flexible part (5), the tapering part (6), or the other end of the manipulating part (8) or in close proximity thereto.
