ABSTRACT:
A urethral catheter designed to employ the principle of urethral irrigation with the patient's own urine to combat rising infection. This irrigation is achieved by having the section of the catheter which lies in the urethra equipped with windows which are arranged so that large surface areas of the urethral mucous membranes are irrigated by urine. Through judicious positioning of a mandrin in the catheter's lumen one can achieve a forced flow of urine through these windows and between the catheter and the urethral mucous membranes, the flow returning through further windows into the hollow interior of the mandrin and proceeding out of the body to a drainage system.
