Abstract

The present invention is for radiation diagnosis and/or therapy in or near body cavities accessible through existing orifices. At least one balloon of a catheter and balloon assembly is inflated by fluid communication through the catheter. Several embodiments provide for diagnostic procedures or radiation therapy, at times in association with one or more of formation of seals, control of movement, nutrient passage and drainage. When radiation therapy is provided, rods or other radiotherapeutic items are secured, positioned or inserted along the contour of the surface of the balloon and are thus deployed to treatment position by balloon inflation.
