ABSTRACT:
An implantable brachytherapy device includes a biocompatible outer capsule containing a radiation shielding element and a radioactive isotope between the shielding element and the wall of the outer capsule. When the device is at body temperature, radiation is emitted by the isotope through the wall of the outer capsule. When a predetermined amount of energy is applied to the device, the shielding element is adapted to at least partially surround the isotope, and thereby at least partially prevent the transmission of radiation through the outer capsule.
