Abstract
To deliver a controlled dosage of an insoluble material into a living body, the material is provided in measured amounts in vials, and a system is provided for flushing the entire content of insoluble materials from the vial into the body. Insoluble radioactive material, such as glass microspheres incorporating radioactive isotopes, are packaged in a plurality of vials, preferably with different amounts of material. An accurate dosage of radioactivity can be delivered by administering the entire contents of one or more vial(s) according to the sum of radioactivity in selected vials as determined by the initial measurement of radioactivity and by the natural half-life of the isotope.
