A staple delivery applicator for delivering radioactive staples during brachytherapy medical treatment has an actuating device for attaching source staples located distally thereform. The actuating device is removably attachable to an actuator arm on a proximal end. A staple applicator cartridge holder is attached to the actuator arm on a distal end. The staple applicator cartridge is mountable in the holder and has slots for mounting of radioactive source staples therein. An anvil therein crimps the staples. The staple applicator cartridge holder is removably mountable in a connector and the connector is also removably mounted to a surgical staple holder. A trigger device has a control for closing the anvil of the cartridge holder and for firing of the source staples in the cartridge therein to cause the staples to crimp, and a control for opening the anvil and releasing the trigger device from the actuator arm.

Delivery applicator for radioactive staples for brachytherapy medical treatment

A gamma radiation source comprisesSelenium wherein theSelenium is provided in the form of compounds, alloys or mixtures with one or more nonmetals which upon irradiation do not produce products capable of sustained emission of radiation which would unacceptably interfere with the gamma radiation ofSelenium. A further gamma radiation source comprisesSelenium wherein theSelenium is provided in the form of compounds, alloys or mixtures with one or more metals or nonmetals, the neutron irradiation of which does produce products capable of sustained emission of radiation which would acceptably complement the gamma radiation ofSelenium. Further, the gamma radiation source may have components that are separately irradiated before being combined and the components may be of natural isotopic composition or of isotopically modified composition so that the subsequent radiation peaks may also be adjusted in relative frequency.

Gamma radiation source

One gamma radiation source comprisesSelenium or a precursor thereof, wherein theSelenium is provided in the form of one or more thermally stable compounds, alloys or mixtures with one or more nonmetals which upon irradiation do not produce products capable of sustained emission of radiation which would unacceptably interfere with the gamma radiation ofSelenium. A further gamma radiation source comprisesSelenium or a precursor thereof, wherein theSelenium is provided in the form of one or more thermally stable compounds, alloys or mixtures with one or more metals or nonmetals, the neutron irradiation of which does produce products capable of sustained emission of radiation which would acceptably complement the gamma radiation ofSelenium. Further, the gamma radiation source may have components that are separately irradiated before being combined and the components may be of natural isotopic composition or of isotopically modified composition so that the subsequent radiation peaks may also be adjusted in relative frequency.
