Abstract
The invention relates to an apparatus and a method useful for non-surgical embryo transfer or artifical insemination of mammals. An apparatus for depositing media into the uterus of a mammal includes a conical chamber that has a plurality of perforations and flaps. An exterior spiral formation is configured for traversing or penetrating cervical passageway. A sheath having a frusto-conical rearward end extends axially from an aft end of the conical chamber. A tubular depositing chamber extends axially from the conical chamber to a position beyond a fore end of the conical chamber. Coupled to the rearward end of the depositing chamber is an embryo or semen packaging unit. The tubular depositing chamber has an end that has an aperture to permit the flow of semen out of the depositing chamber and into the uterus. The invention also involves a method for depositing of embryos or semen into a uterus of a mammal by a) inserting a conical chamber having a fore end and an exterior spiral formation into a cervix of a mammal, b) securing the conical chamber with the walls of the cervix, c) projecting a depositing chamber through an interior portion of the conical chamber, d) moving the depos…
