Estimating the term…
An instrument used for brachytherapy delivery in the treatment of cancer by radiation therapy including a handle having first and second handle actuators; an end effector; and an instrument shaft that connects the handle with the end effector. The end effector has first and second adjacent disposed staple cartridges that each retain a set of staples. The first mechanism is for holding standard staples in a first array, and dispensing the standard staples under control of the corresponding first handle actuator. The second mechanism is for holding radioactive source staples in a second array, and dispensing said radioactive source staples under control of the corresponding second handle actuator. 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 having a plurality of slots for mounting of radioactive source staples therein. An anvil therein crimps the staples.

A staple construction used for brachytherapy delivery in the treatment of cancer by radiation therapy, said staple construction comprised of:
A combination staple used for brachytherapy delivery in the treatment of cancer by radiation therapy and an applicator for applying the staple, said staple including a base and a radioactive source, said base formed as a sleeve having an elongated cavity for receiving and holding said radioactive source therein, and tissue piercing ends connected with said base and formed as legs of the staple, said staple positionable for piercing tissue in performing a surgical procedure at a surgical margin while concurrently securing said radioactive source in a fixed position at said surgical margin, said applicator constructed and arranged for the support of one or more staples and for applying the staple at the surgical margin.
A method of forming a staple that is to be used for brachytherapy delivery in the treatment of cancer by radiation therapy, including providing a base and a radioactive source, forming the base as a tubular cavity for receiving and holding the radioactive source therein, providing end wires that serve as tissue piercing legs of the staple, and securing the respective end wires to opposed ends of the tubular base.
