A cylindrical antiseptic cuff with an inner shaft to be placed along a urinary catheter within the patient's distal urethra for preventing infection associated with bacterial migration along the catheter surface. In a preferred embodiment, a thin infusion port is provided for charging or repleting the cuff with antimicrobial substance. The antiseptic cuff imparts a sterile, occlusive interface between catheter shaft and distal urethral mucosa, and precludes incidental sliding movements of the catheter. In an alternative embodiment, an antiseptic cuff is constructed of several concentric layers of antiseptic material, sequential outer layers being manually removable for eradicating surface pathogens while the catheter remains in position. A longitudinally directed cleft may be implemented to afford opening of the cuff for lengthwise mounting onto a catheter.
