  • Patent number: 4960412
    Abstract: A catheter introducer valve assembly of a catheter introducer leading to a blood vessel of a patient for positioning at least one catheter tube through the catheter introducer and its sheath to a blood vessel of a patient. The valve assembly unit has first and second valves, the first valve being for preventing or minimizing the flow of blood from the valve assembly unit when the catheter tube is absent from the catheter introducer and the second valve being for preventing or minimizing the flow of blood when the catheter tube is present in the catheter introducer. The first valve, which is made of a flexible, resilient material, is shaped as a disk having a valve slit, such a duckbill valve, positioned diametrically across the passage of the valve assembly body. The rim surface of the valve disk has a slightly smaller diameter than the diameter of the positioning area of the inner surface of the valve assembly body where the valve disk is located so that a cylindrical space is formed therebetween.
