A source wire for radiation treatment of diseases is provided, comprising a relatively long elongate flexible wire having a proximal end and a distal end, the distal end of the wire having a wire end face substantially perpendicular to a longitudinal axis of the wire; a relatively short flexible tube having a proximal end and a distal end, the distal end of the tube being sealed, the tube having a tube end face at the proximal end and substantially perpendicular to the distal wire end face of the wire, the tube having an inner diameter defining a cavity; and a core capable of being irradiated to form at least one radioactive source positioned within the cavity.

Source wire for radiation treatment

There is provided a manually operable afterloader ( ) for use during radiation therapy treatment of a patient. The afterloader ( ) includes a sourcewire reel ( ) having a circumferential groove, dual sized or stepped ( ), for receipt of a non-radioactive portion of a sourcewire ( ) and a shield capsule ( ) having a passageway therethrough for receipt of a radioactive portion of a source wire ( ). A cranking mechanism ( ) is provided to rotate the sourcewire reel ( ) and drive the radioactive sourcewire ( ) out of the shield capsule ( ).
