Abstract

This invention is a brachytherapy device (10) in the form of a radioactive coiled wire (10). The wire (10) used to form the coil (10) is typically between 10 micrometers to 200 micrometers in diameter. The coil (10) formed from the wire (10) has an outer diameter of between about 25 micrometers, and about 1000 micrometers. The coil (10) can be formed first from a wire (10), and then made radioactive. Alternatively, the wire (10) can be made radioactive first, and then formed into a coil. Methods of incorporating a radioisotope into the wire (10) or coil (10) include, for example, nuclear transformation, ion implantation, which do not affect the flexibility, and other mechanical properties of the coil (10). Thin radioisotope films (un-numbered) can also be applied to the wire (10).
