Abstract

A retainer for cattle implants comprising a main body portion and a plurality of retention elements capable of implantation into cattle along with the implant itself. An injector and new process of implanting is also disclosed wherein a double acting trigger mechanism on an injector properly loads a retainer and implant into a needle and then injects the retainer and implant into the animal.

Claims

1. A process for implantation of an implant in an animal including the steps of positioning an implant and retainer in a side by side substantially abutting relationship, injecting said implant and said retainer into the animal such that said implant and retainer are disjoined from one another such that said retainer and implant move in only one direction into the animal, and locking the retainer and implant substantially against the hide of the animal.

2. The process of claim 1, wherein the injection of the implant and retainer is performed simultaneously.

3. The process according to claim 1 further comprising enabling said implant to dissolve in said animal after a period of time and said retainer remaining in said animal.

4. A process for implantation of a growth hormone implant in an animal comprising the steps of:

(1) Confining the portion of the animal to be implanted;

(2) Penetrating the skin with a needle of an injector;

(3) Loading both a retainer and the implant into the injector such that said retainer and implant are in a substantially abutting relationship;

(4) Injecting the implant and retainer into the animal such that said implant and retainer are disjoined from one another;

(5) Locking the retainer and implant against the hide of the animal; and

(6) Withdrawing the needle of the injector from the animal.

5. The process according to claim 4 further comprising enabling said implant to dissolve in said animal after a period of time and said retainer remaining in said animal.

6. A process for implantation of a growth hormone implant in an animal comprising the steps of:

(1) Confining the portion of the animal to be implanted;

(2) Loading both a retainer and the implant into an injector such that said retainer and implant are in a substantially abutting relationship;

(3) Penetrating the skin with a needle of the injector;

(4) Injecting the implant and retainer into the animal such that said implant and retainer are disjoined from one another and move only in the direction of the needle;

(5) Withdrawing the needle of the injector from the animal;

(6) Preventing reverse movement of the retainer and implant in the portion of the animal where the retainer and implant have been injected; and

(7) Locking the retainer and implant in position in the implantment portion of the animal.

7. The process according to claim 6 further comprising enabling said implant to dissolve in said animal after a period of time and said retainer remaining in said animal.

8. A process for implantation of an implant in an animal comprising the steps of:

positioning a dissolvable implant and a retainer in a side by side substantially abutting relationship;

injecting said dissolvable implant and said retainer into the animal such that the retainer and implant are disjoined from one another and move in only one direction into the animal; and

enabling said implant to dissolve in said animal after a period of time.

9. A process for implantation of an implant in an animal comprising the steps of:

positioning a dissolvable implant and a retainer in a substantially abutting relationship;

injecting said dissolvable implant and

said retainer into the animal such that said implant and retainer are disjoined from one another; and

enabling said implant to dissolve in said animal after a period of time.

10. The method of claim 9 further comprising said retainer remaining in said animal after dissolving of said implant.

11. A process for implantation of a growth hormone implant in an animal comprising the steps of:

(1) confining the portion of the animal to be implanted;

(2) penetrating the skin with a needle of an injector;

(3) loading both retainer and dissolvable implant into the injector such that said retainer and implant are in a substantially abutting relationship;

(4) injecting the dissolvable implant and retainer into the animal such that said dissolvable implant and retainer are disjoined from one another;

(5) withdrawing the needle of the injector from the animal; and

(6) enabling said implant to dissolve in said animal after a period of time.

12. The process according to claim 11 further comprising said retainer remaining in said animal after the dissolving of said implant.
