Intermittent catheter assembly and kit
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.

8. The intermittent catheter assembly of claim 6 wherein the second end of the sheath is secured to generally diametrically opposed portions of the applicator.
9. The intermittent catheter assembly of claim 6 wherein the applicator includes a drainage lumen wherein the second end of the sheath is secured about the drainage lumen so that the urine flow path defined by the inner sleeve portion is in fluid communication with the drainage lumen.
10. The intermittent catheter assembly of claim 9 wherein the drainage lumen is at least partially defined by a drainage tube that extends distally from a distal surface of the applicator.
11. The intermittent catheter of claim 10 wherein the drainage tube functions as a guide for guiding insertion of the elongated introducer element into the at least one opening of the applicator.
12. The intermittent catheter assembly of claim 6 wherein the applicator includes two openings for receiving the elongated introducer element and the elongated introducer element includes a pair of opposed arms wherein each arm is received into one of the openings and into the space defined between the outer and inner sleeve portions.
13. The intermittent catheter assembly of claim 1 wherein the elongated introducer element comprises a tube having a single slit extending along the entire length thereof from the proximal insertion end to the distal end.
14. The intermittent catheter assembly of claim 1 wherein the proximal insertion end of the elongated introducer element is beveled to be at other than a right angle to an axis of the elongated introducer element to aid insertion into a urethra during a catheterization procedure.
15. The intermittent catheter assembly of claim 1 wherein the proximal insertion end of the elongated introducer element is beveled so as to be at an angle of between about 15° and about 30° to an axis of the elongated introducer element.
16. The intermittent catheter assembly of claim 1 wherein the elongated introducer element includes opposed elongated arms defining the slit therebetween.
17. The intermittent catheter assembly of claim 1 wherein the slit extending longitudinally along at least a substantial portion of the length of the elongated introducer element has a width of between about 1.0 mm and 1.5 mm.
18. The intermittent catheter assembly of claim 1 wherein the sheath is formed of a flushable material.
19. The intermittent catheter assembly of claim 1 wherein the sheath is formed of a biodegradable material.
20. An intermittent catheter assembly, comprising:
an elongated introducer element having a proximal insertion end and a distal end remote from the proximal insertion end, the elongated introducer element being formed of a flexible material adapted for insertion into a urethra during a catheterization procedure, the elongated introducer element having at least one slit extending longitudinally along at least a portion of the elongated introducer element;
an applicator having an opening for receiving the elongated introducer element, and a sheath having a first end secured to the applicator about the opening and a second end defining a discharge opening;
the second end of the sheath being inverted relative to the first end of the sheath and extending into the opening in the applicator to define inner and outer sleeve portions wherein the inner sleeve portion defines a flow path for urine through the discharge opening;
a holding element associated with the second end of the sheath for extending the inner sleeve portion through the at least one slit of the elongated introducer element so as to dispose the inner sleeve portion within the elongated introducer element wherein the inner sleeve portion covers an inner surface of the elongated introducer element to thereby separate the inner surface of the elongated introducer element from the urine flow path; and
as the elongated introducer element is inserted through the opening of the applicator, the outer sleeve portion extends over an outer surface of the elongated introducer element.
21. The intermittent catheter assembly of claim 20 wherein the proximal insertion end of the elongated introducer element is beveled to be at other than a right angle to an axis of the elongated introducer element to aid insertion into a urethra during a catheterization procedure.
22. The intermittent catheter assembly of claim 20 wherein the proximal insertion end of the elongated introducer element is beveled so as to be at an angle of between about 15° and about 30° to an axis of the elongated introducer element.
