ABSTRACT:
An apparatus used for radiotherapeutic purposes, designed to store a number of radioactive-source carriers and to facilitate their selective ejection via respective sheaths to remote applicators designed to contact anatomical parts to be treated, comprises a cylindrical body inside a metallic enclosure, the body being formed with a plurality of axially extending cylindrical cavities each adapted to accommodate a source carrier. Certain of these cavities, referred to as active, are open at both ends and are connected via respective conduits with associated entrance and exit connectors on the outer surface of the enclosure, the exit connectors being engageable by the ejection sheaths. The remaining cavities, serving for the storage of source carriers, communicate by way of other conduits with ancillary connectors, also on the outer enclosure surface, that can be linked by a transfer tube to the exit connector of a selected active cavity which is to be loaded with a source carrier or from which such a carrier is to be withdrawn. The displacement of any carrier into and out of an applicator or into and out of storage is performed by a flexible driving cable passing through the entrance connector of a selected active cavity.
