ABSTRACT:
This invention is a veterinary instrument for non-surgically implanting in an animal's uterus a live embryo for the purpose of inducing pregnancy. The device is comprised of a tip element having a small, medium and large diameter bore partially therethrough, an exit passage in communication with the small diameter bore terminating at a laterally positioned countersunk exit hole. An embryo containing straw is positioned within and compressed by the medium diameter bore. The tip is screw connected to a plunger element having a rod therethrough which is adapted to fit within the embryo containing straw and to force the contained embryo out of the countersunk hole. A modification of the instrument includes a thumbscrew positioning ring on the end portion of the plunger element adapted to mark the position of the countersunk hole so that it may be properly oriented when it is within the animal.
