An implant dart (10) has a head (20) of solid material and a tubular body (30) that contains one or more drug delivery implant packages (50). The head has a blade (27) at its front end with a chisel-type point with a beveled end (28) and a scooped face extending rearwardly to the body. The body is formed as a helical coil (32) 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 (60) from the head to the interior of the body provides fluid communication between the subject's body fluids and the implant packages. The complete system comprises at least one dart, an injection mechanism which retains a subject's body part on a platen, and feeds darts into the body part generally parallel to the platen.
