  • Low friction inner lumen
    Patent number: 5607404
    Abstract: A catheter body with a single, centrally located guidewire lumen having an odd number of longitudinally extending, generally planar, inner wall surfaces. Each wall surface has a radius of curvature in excess of the guidewire's radius of curvature, as measured in cross section. The wall surfaces are joined to one another by longitudinally extending corner surfaces, each corner surface having a radius of curvature less than the guidewire's radius of curvature, as measured in cross section. The wall surfaces and corner surfaces are formed of alternating thicknesses to the outer diameter.
