Implant gun
First Claim
1. An implant gun for depositing items such as pellets, identification means and the like subcutaneously, said implant gun comprising a movable carrier, a hollow needle extending from the forward end of said carrier and movable therewith for creating a cavity in the tissue at the implant site when said needle is inserted into said tissue, means for retaining the item to be implanted in position for implanting through said needle, ram means extending into said carrier and engagable with said item, said ram means and said carrier being relatively movable generally forwardly and rearwardly, and operating means for moving said needle and carrier rearwardly while holding said ram means stationary relative to the implant site so as to withdraw said needle from the implant site while holding the item to be implanted in the cavity created at the implant site as said needle is withdrawn.

Abstract
An implant gun for depositing pellets or the like subcutaneously. The gun includes a hollow needle through which a number of pellets are dispensed from a cartridge that is positioned either inside the needle or in an ante-chamber. The action of the gun is such that the pellets are gently deposited in the tissue as the needle is withdrawn from the cavity formed in the tissue at the time the needle was inserted. This technique practically eliminates any breaking of the fragile pellets and reduces the trauma of their insertion into the tissue. The implant gun also includes a unique ram activating mechanism that frees one of the hands of the operator so that the implanting procedure can be conducted without assistance. The implant gun is also easily adapted for use in implanting single items other than pellets, such as identification tags for animals.
