ABSTRACT:
An apparatus and method of forming a radioactive stent having a radioactive layer. A solution containing a radioactive isotope depositing substance in solution is provided and placed into contact with the stent or any other substrate material capable of receiving the radioactive isotope. The radioactive isotope is deposited on the stent or substrate material. Preferably a phosphorous isotope is used and the solution is polymerized forming polymer chains containing the radioactive isotope. In this embodiment, the phosphorous is bonded with the substrate material in a phosphorous-oxygen-phosphorous network.
