  • Flexible inner liner for the working channel of an endoscope
    Patent number: 6315715
    Abstract: A tubular member useful as an inner liner for the working channel of a flexible endoscope has a distal portion which is specially treated to make it highly flexible and resistant to kinking or collapsing when it bends with the flexible section of the endoscope. The tubular member is also useful as a catheter device or as a component of a catheter device or catheter system. A multiplicity of external ridges on the distal portion of the tubular member reinforce the tubing wall and prevent kinking or buckling of the wall or collapsing of the inner lumen. The external ridges may be formed by convolutions of the tubing wall or by external threads which are formed on the exterior of the tubing wall within the flexible distal portion. An outer helical reinforcing coil may be added between the external ridges to further reinforce the flexible distal portion of the tubular member from kinking or collapsing.
