Abstract
Disclosed is a medical vascular guide wire made of a synthetic resin hollow monofilament. The guide wire is comprised of a tip part, a flexible part having a smaller diameter than the other parts, a tapering part and a manipulating part, these four parts continuously forming in line, in that order, along the monofilament axis. At least the tip part and the manipulating part have X-ray impermeable material inserted in the respective hollows thereof. A self-guiding type catheter made of a synthetic resin, multi-hollow monofilament is also provided. The catheter is comprised of a tip part, a flexible part having a smaller diameter than the other parts, a tapering part and a manipulating part, these four parts continuously formed in line, in that order, along the monofilament axis: The catheter has at least two hollows extending at least from one end of the manipulating part to the tapering part or to the other end of the manipulating part or to a point in close proximity to said other end of the manipulating part. At least one of the hollows has an X-ray impermeable material inserted at least within the hollow in the manipulating part, and the other hollow or at least one of the other hollows form a lumen for permitting a liquid and/or a gas to pass therethrough.
