Claims
- 1. The method of fabricating a radioactive source wire for in situ treatment of malignancies in patients, comprising:
- assembling a source composed of material capable of activation to a radioactivity level sufficient for said treatment with a flexible elongate delivery wire of substantially uniform diameter to become a substantially integral unit, by introducing the source into a hole formed in the tip of a delivery wire larger than the desired diameter of the source wire to be used for the treatment and drawing the assembly down to the desired diameter.
- 2. The method of claim 1, further including:
- irradiating the assembly in a nuclear reactor to a source radioactivity level of at least 10 curies while limiting the delivery wire to a relatively low level of radioactivity by restricting its composition to a material having a considerably shorter half-life than that of said source.
- 3. The method of claim 2, wherein the source is composed of relatively pure iridium.
