    • A cystostomy device for implant in a patient includes a transcutaneous sleeve with an outer surface and an inner surface, a flange connected to the transcutaneous sleeve, adapted to reduce contamination of the outer surface of said transcutaneous sleeve, a catheter defining a passage for the flow of fluids from within the patient to outside the patient, the inner surface of the transcutaneous sleeve defining a path through which the catheter passes, and an anchor adapted for implantation into the biological tissue of the patient, the anchor selectively and reversibly connecting to the catheter and the transcutaneous sleeve. At least one microbe resistance zone is included on the inner and/or outer surfaces in any of the sleeve, the flange, and the catheter. The microbe resistance zone may be formed by or on the surfaces of the sleeve, flange and catheter, as applicable, or may be adhered to the device as tape that may be rolled.
