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.

Handheld radiation delivery system

A system for supplying optical power uses an optical switch or shutter at the handpiece. The optical switch is positioned between an open light-transmitting position and a closed light-reflecting position. A detector at the base of the system can be used to detect the position of the optical shutter in some situations. This can be used to control the operation of a high-intensity light source. In this manner, the system can be controlled at the handpiece without using electrical power at the handpiece.
