ABSTRACT:
A composite source wire for use in a patient's body to irradiate preselected tissue by localized in vivo radiation with a radioactive source, via a path from a point external to the body to the site of the tissue to be irradiated. The source wire includes a thin elongate stainless steel wire with a substantially cylindrical central aperture at its distal tip, a cylindrical radioactive fiber core tightly sealed without welding within and abutting at one end the floor of the aperture and at the other end a cylindrical plug sealing the aperture at the distal tip of the source wire, the distal tip being securely enclosed about the plug and forming a tapered tip portion at that point. The source wire has an overall diameter sized to permit ease of movement through the path formed by a vessel or duct in the patient's body during advancement to the site of the tissue to be irradiated and to allow its retraction along the path from the point external to the body.
