The invention comprises a system for the long term continuous delivery of medication to hollow body organs. It is particularly suited for the deivery of chemotherapy drugs to lesions in the walls of those organs. The invention, specially designed for the treatment of the prostate gland, comprises a urinary drainage catheter which has an additional lumen within the wall thereof, said lumen proximate end connected to a space external of the catheter wall enclosed by a porous membrane. The distal end of the lumen, which is external to the penis when the catheter is positioned in the body, has a valved end for introduction of liquid medication therethrough. In use, the catheter is placed within the urethra, with the porous membrane portion adjacent the prostatic ducts. Medication introduced through said valve is transmitted along the lumen into the space between the catheter and the porous membrane, through the membrane and into contact with the prostatic ducts.
