International ClassA61N 500AbstractA flexible, radioactive radiation source in the form of a wire or other elongated shape, comprising a matrix of a ductile and/or plastic binder material and a radioactive and/or activatable material. The elastic binder material is preferably a metal, a metal alloy, or a radiation resistant plastic material, or a mixture of these, and the radioactive material, or activatable material once activated, is a β-emitter, a γ-emitter, or an x-ray emitter. The source may be contained, for example, within a tube, capsule, or coating. The flexible, radioactive radiation source may be used for intravascular radiation treatment of cancer, tumor, non-malignant cell growth, scar tissue, or to prevent restenosis. | |
