ABSTRACT:
A urinary catheter assembly having a catheter tube disposed within an outer sheath, a closure member being provided over the distal end of the sheath. Penetration of the catheter assembly into the urethra is limited by the provision of a stop member extending outwardly from the sheath and spaced from the sheath's distal end by a specific distance to allow the sheath to pass bacteria in the outer portion of the urethra, but penetrate no further.
