A sheath introducer for a catheterization or similar procedure comprises a main body having an exterior tapered sidewall, an interior lumen, a beveled top surface and an annular boss extending from the top surface; a rotating section having an exterior sidewall, an interior lumen, a beveled bottom surface having a recessed portion dimensioned so as to be received within the main body annular boss, and a top surface having an annular shoulder extending therefrom creating a recess; a cannula extending from the bottom end of the main body; and, a hemostatic valve having an access port and a fluid tight slit opening and seated within the upper portion and maintained by a cap, the valve being maintained within the rotating section recess and preferably slightly compressed when the rotating section and main body are assembled. When assembled, the rotating section can rotate up to approximately 180 DEG , affording approximately a 45 DEG angle between the main body lumen and the rotating section lumen while maintaining an open passageway for insertion of catheters or other objects. Optionally, an angled sideport in fluid communication with the main body lumen extends from the main body./!
