A flexible source wire (10) is provided containing a radioactive source (160) that is capable of maneuvering through a tortuous narrow passage to a treatment site within the body. This source wire (10) includes a thin flexible housing tube (120), housing therein a flexible backbone wire (130), wherein both the tube (120) and the wire (10) are constructed from a material exhibiting little or no memory retention when bent. A radioactive core (160) is provided in the proximal end of the flexible housing tube (120) and abuts the proximal end of the backbone wire (130). Both ends of the source wire (10) are sealed and the proximal end of the source wire (10) is rounded to allow ease of movement as it travels through the bends and turns in the body. |
