ABSTRACT:
A flexible source wire is provided containing a radioactive source that is capable of maneuvering through a tortuous narrow passage to a treatment site within the body. This source wire includes a thin flexible housing tube, housing therein a flexible backbone wire, wherein both the tube and the wire are constructed from a material exhibiting little or no memory retention when bent. A radioactive core is provided in the proximal end (i.e., the treatment end) of the thin flexible housing tube and abuts the proximal end of the backbone wire. Both ends of the source wire are sealed and the proximal end of the source wire is rounded to allow ease of movement as it travels through the bends and turns in the body.
