Apparatus for trans-cervical artificial insemination and embryo transfer

摘要

The invention relates to an apparatus and a method useful for non-surgical embryo transfer or artificial insemination of mammals. An apparatus 10 for depositing media 11 into the uterus of a mammal includes a conical chamber 12 that has a plurality of perforations 36 and flaps 36a. An exterior spiral formation 18 is configured for traversing or penetrating cervical passageway. A sheath 20 having a frusto-conical rearward end 22 extends axially from an aft end 16 of the conical chamber 12. A tubular depositing chamber 30 extends axially from the conical chamber 12 to a position beyond a fore end 14 of the conical chamber 12. Coupled to the rearward end 43 of the depositing chamber 30 is an embryo or semen packaging unit 40. The tubular depositing chamber 30 has an end 32 that has an aperture 34 to permit the flow of semen 11 out of the depositing chamber 30 and into the uterus. The invention also involves a method employing the apparatus 10 described.
