Abstract

The present invention includes an indwelling urinary catheter operable for flushing fluid through the urethra. The catheter has an elongated tubular catheter body, a discharge lumen disposed within the catheter body operable for discharging urine from a patient, a fluid flush lumen disposed within the catheter body operable to receive a flushing fluid, and at least one permeable sheath in fluid communication with the fluid flush lumen, wherein a plurality of protrusions of variable shapes, sizes, and arrangements are disposed on the outer surface of the sheath and are operable to create space between the catheter body and the urethra for improved flushing. Alternative embodiments include circumferential ridges and eluting pores disposed on the outer surface of the sheath wherein the distance and height between the ridges as well as the density of the eluting pores decrease in the direction of the proximal end of the sheath.
