Abstract: A pistol-shaped medicament implant applicator with a needle mounted on the forward end thereof, and a multichambered medicament cartridge adapted for insertion into the implant applicator wherein the applicator mechanism:transports a plunger through one of the medicament containing chambers in the cartridge into the implant needle and forces medicament out the needle front;moves the needle relative to an abutment on the front face of the applicator adapted to be held against the skin of the animal being implanted, the relative movement forcing withdrawal of the needle, resulting in deposition of the medicament in the needle track;retracts the plunger so as to clear needle and cartridge; and,shifts the cartridge the spacing between adjacent chambers therein and indexes the next medicament containing cartridge chamber to the needle bore and the path of the plunger.
