  • Patent number: 5470322
    Abstract: Multilumen catheters are provided with an axially decreasing stiffness by the incorporation of a hollow tube formed of a relatively stiff material into the catheter construction. The tube may either encircle the catheter as an external shell or reside inside one of the lumens as a liner. The stiffness variation may be attained by extending the hollow tube only part of the distance from the proximal to the distal ends of the catheter or by varying the construction of the hollow tube.
