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