Injection dart system
First Claim
1. An implant dart for insertion into an animal body, said implant dart comprising:
- a forward head having a first means for penetrating into body tissue so as to permit the entire dart to enter and lodge totally within the body and a second means for non-removably implanting said entair dart within said body,a tubular body oriented behind said head, said tubular body having a compartment for holding at least one drug-delivery implant container;
said compartment in said tubular body being in fluid communication with said head by a passage defined between said head and said tubular body to permit entry of fluids within the animal body into said compartment;
said forward head and said tubular body being formed from material biologically compatible with said animal body.

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.

11. An implant dart for insertion into an animal body, said implant dart comprising:
-
a head having means for penetrating into body tissue so as to permit the entire dart to enter the body; a tubular body having a compartment for holding at least one drug-delivery implant container;
said tubular body being pervious to fluids within the animal body so as to permit entry of said fluids within the animal body into said compartment;said head comprising a front end of said dart and said tubular body comprising a rear end of said dart, said front end of said head being constructed to be sufficiently sharp to pierce body tissue; said tubular body being flexible; said tubular body being formed of at least one turn of a coil of material, said at least one turn being of a helical shape; and the coil having a plurality of turns and stops between the turns of the coil that engage to limit compressive force along the length of the tubular body.

18. An implant dart for insertion into an animal body, said implant dart being formed from material biologically compatible with said animal body and adapted to be non-removably implanted in said animal body, said implant dart comprising at least two separate components including:
-
a head portion comprising a forward end of said dart, said head portion having a first means for penetrating the animal body to permit said entire dart to enter and lodge totally within the animal body and a second means for non-removably implanting said entair dart within said body, a tubular body being oriented behind said forward head portion and comprising a rear end of said dart, said tubular body being adapted for holding at least one drug-delivery implant container therein; said forward head portion defining at least one opening therein in fluid communication with said tubular body for releasing substances in said drug-delivery implant container from said dart; said forward head and said tubular body being formed from material biologically compatible with said animal body.

19. An implant dart for insertion into a subject comprising:
-
a head having a front and rear end and an elongated blade at its front end; a flexible tubular body at the rear end of said head formed of a coil of material; at least one implant within said tubular body; and said head having a passage therethrough communicating with the interior of said tubular body.

20. An implant dart for insertion into an animal body, said implant dart comprising:
-
a head comprising a front end of said dart and having a first means for penetrating into body tissue so as to permit the entire dart to enter and lodge totally within the body and a second means for non-removably implanting said entair dart within said body, a flexible tubular body comprising a rear end of said dart and having a compartment for holding at least one drug-delivery implant container; a passage through said head to the interior of said tubular body for providing access into said compartment by fluids within the animal body; an opening at the end of the tubular body remote from the head to permit insertion of an implant into said tubular body; said forward head and said tubular body being formed from material biologically compatible with said animal body.

21. A method for implanting a sustained release composition into an animal body, said method being performed with an implant dart including a head having means for penetrating into body tissue so as to permit the entire dart to enter the body, a tubular body having a compartment for holding a drug-delivery implant container, a passage between said head and said compartment to permit entry of fluids within the animal body into said compartment, said method comprising the steps of:
-
introducing into said compartment a drug-delivery implant containing said sustained release composition; and inserting said implant dart into the interior of a part of the animal body so that the dart is entirely within the body part and said fluids within the animal body are in fluid communication with said drug-delivery implant in said compartment. - View Dependent Claims (22, 23)
