An intermittent catheter assembly and kit comprising an elongated introducer element formed of a flexible material adapted for insertion into a urethra during a catheterization procedure. The introducer element has at least one slit extending longitudinally along a substantial portion of its length. The catheter assembly also includes an applicator having an opening, and a sheath having a first end that is secured to the applicator about the opening. The sheath also has a second end defining a discharge opening which is inverted relative to the first end of the sheath to define inner and outer sleeve portions. The inner sleeve portion defines a flow path for urine through the discharge opening. The applicator receives the introducer element through the opening and extends the outer sleeve portion over an outer surface of the elongated introducer element to separate it from the urethra.
