Abstract
A source wire for delivery of a radioactive source to the site of a deep body tumor via a relatively narrow passageway includes a relatively thin elongate flexible tube, a solid core running through substantially the entire length of the tube and at least slightly beyond one end of it to strengthen it against collapse while maintaining its flexibility, and a relatively short rigid sleeve overlying the exposed portion of the core and abutting that end of the tube. The sleeve extends at least slightly beyond the otherwise exposed core to accept insertion of the cylindrical filament-like radioactive source to abut against the core. The outer diameter of the sleeve is substantially equal to the outer diameter of the tube and to that of a sheath which overlies the radioactive source and abuts against the end of the sleeve opposite to that abutting the end of the tube. The sleeve is welded to the core and crimped onto the radiactive source for substantially permanent engagement therebetween.
