Abstract

A flexible source wire (10) is provided containing a radioactive source (16) that is capable of maneuvering through a tortuous narrow passage to a treatment site within the body. The source wire (10) includes a thin flexible housing tube (12), housing therein a flexible backbone wire (14), both the tube and the wire being constructed from a material exhibiting little or no memory retention when bent. A radioactive source (36) is provided in the proximal end of a thin flexible housing tube (32). This radioactive source (36) is contained in a capsule (40) abutting the proximal end of the backbone wire (34) all within a thin wall encapsulating material (32). Both ends of the source wire (10) are welded shut to form a tight seal and rounded to allow ease of movement as it travels through the bends and turns in a body. The housing tube (12) is coated before the loading of the radioactive material with a non-oxidizing agent (40) such as gold.
