摘要

A handheld radiation delivery system is disclosed that includes a two-part delivery module comprising a reusable portion that contains a radioactive source wire and a disposable portion that includes a drive assembly for moving the radioactive source wire between storage and treatment positions. A disposable applicator tip is provided that includes a cannula for receiving the radioactive source wire when in the treatment position and a mechanism for limiting the number of uses of the device. A handheld cable actuator is operatively connected to the disposable portion of the handpiece to impart motion to the source wire.
