Abstract: An implant dart has a head of solid material and a tubular body that contains one or more drug-delivery implant packages. The head has a blade at its front end with a chisel type point with a beveled end and a scooped face extending rearwardly to the body. The body is formed as a helical coil that makes the body tubular and permits the coil turns to be compressed and engage to make the body relatively rigid when the dart is injected into the subject. A passage from the head to the interior of the body provides fluid communication between the subject's body fluids and the implant packages. Wings extend from the head to guide entry of the dart into the subject and to lock it against withdrawal. The complete system comprises at least one dart and an injection mechanism which retains a subject's body part on a platen and feeds darts into the body part and generally parallel to the platen.
