Patent ID: 11103336

Abstract:
The present invention provides apparatus and methods for artificial insemination or in-vitro fertilization for use with livestock that maintains the sterility of the semen or embryo(s) until deposited at an optimum location in the reproductive tract of the animal without the maneuvering or tissue injury problems associated with existing devices. The invention includes a uniquely shaped opening that is provided at the tip of a sheath that is used with an artificial insemination gun. A plug or diaphragm having a rounded (convex) exterior surface completely covers the opening at the tip of the sheath, and seals it closed in a smooth, flush engagement to prevent contaminants from collecting upon the tip, or entering into the sheath during the trip through the reproductive tract of the animal. Once the sheath is properly placed in the reproductive tract, application of fluid pressure to the inside the sheath causes the plug to move or deform without becoming detached from the sheath, thereby allowing contents of the sheath to exit. The unique tip with its opening and corresponding plug may be provided in a separate cap that is installed at the end of an insemination sheath.
