Abstract (en)
[origin: WO9902194A1] Implantable structures, such as permanently implanted stents and temporarily implanted balloon catheters, are coated with a radioactive material. At least a portion of a surface of the structure is first coated with a substrate material. The radioactive material is then bonded to the substrate material on the structure surface. The amount of radioactive material bonded to the substrate may be selected to provide a desired radioactive dosage for intravascular treatment, anti-tumor treatment, or other therapeutic protocol. Optionally, at least a portion of the bound radioactive material will be coated with a sealing layer.
