Abstract
Locally deposited polymer depots are used as a vehicle for the immobilization and local delivery of a radionuclide or radiopharmaceutical. Radionuclides are incorporated in their elemental forms, as inorganic compounds, or are attached to a larger molecule or incorporated into the polymer, by physical or chemical methods. Ancillary structure may be employed to control the rate of release. Standard radionuclides which have been used for local radiotherapy may be used, such as radionuclides of iodine, iridium, radium, cesium, yttrium or other elements.
