Abstract
An implantable medical device according to the present invention comprises a body, such as a stent or a wire, having a radioisotope or non-radioactive precursor isotope associated with the body. The isotope preferably is disposed on the body using an efficient deposition method, such as an effusion cell. The method reduces the waste of costly isotopes and reduces the buildup of hazardous material in the apparatus. A metal layer may be deposited simultaneously with or subsequent to deposition of the isotope to encapsulate the radioactive isotope.
