Abstract
An instrument for implanting radioactive and/or thermal seeds in body tissue for radiation and/or heat therapy comprises a tubular hypodermic needle barrel affixed to a pistol-grip shaped handle incorporates a reciprocally movable push rod for stripping one such seed from a cartridge containing a plurality of seeds and advancing it to the end of the barrel. Actuation of a trigger in the pistol grip handle causes the barrel to retract relative to the push rod, causing the seed to be deposited in the channel in the body tissue created by the original puncturing thereof by the instrument's barrel.
