    Abstract: The device comprises an injection system, which is made up of a rigid external tubular body (1) that enables it to be inserted into the abdominal cavity of a sow. This body is, in turn, covered by a sterile sleeve (2) that enables it to be used in different animals. A flexible duct (3) runs coaxially and its distal end connects with a bevelled needle (4) that permits insertion in the oviduct (12) at an angle of 45°. The proximal end of the flexible tube connects with a device (6) that includes a sheath (7) closed at the other end by a piston (8) that slides along the inside of the sheath and that enables the precision insertion of low-volume liquids.

  • Publication number: 20110213198
    Abstract: The present invention provides a practical, non-invasive, and efficient method for cryopreservation of an in-vitro-produced porcine embryo. The inventive method treats the NP (such as IVF- or NT-derived) embryo at the one-cell or cleavage stage prior to compaction with high osmolality followed by high speed centrifugation. The high osmolality treatment enlarges the periviteline space, and with centrifugation, enables the separation of the lipids from the cytoplasm. The lipid-separated embryos after high osmolality treatment have been successfully cryopreserved and later recovered and transferred to produce live offspring.

In an embodiment of the present disclosure, one or more cells are biopsied from each of the embryos, and the genetic condition of those cells are determined. Within a group of embryos that each test positive for aneuploidy, the likelihood that each embryo contains euploid cells may be determined from the type of aneuploidy observed in the biopsied cells. This knowledge may be used to make a decision as to which embryos to transfer to a uterus. In an embodiment of the present disclosure, these determinations are made for the purpose of embryo selection in the context of in vitro fertilization.

  • Patent number: 6905458
    Abstract: An echogenic and/or radio-opaque device adapted to permit carrying out removals from the genital organs for analysis, or adapted to promote the transfer of products, particularly gametes or embryos, into the female genital organs, or again adapted to carry out tests for the introduction of catheters into the uterus and to analyze the morphology of the neck of the uterus and of the uterine cavity. The device comprises an echogenic and/or radio-opaque material permitting visualizing by medical imagery, particularly by echography or radiography, the position of the usable orifice or of the distal portion of the device.

  • Publication number: 20040122286
    Abstract: A catheter including a shaft comprising a body with a proximal portion and a distal portion, the body defining an opening from the proximal portion to the distal portion, the distal portion having an end that is beveled in a first direction across an end opening, such that a length of the shaft to a first point on the end is a first length and a length of the shaft to a second point on the end is a second length longer than the first length. A method including placing at least one embryo near an open end of a catheter, inserting the open end of the catheter into an endometrial lining of a subject's uterus, using the catheter to open a flap of the endometrial lining, and transferring the at least one embryo from the catheter to the pocket site.

  • Patent number: RE39533
    Abstract: The A fertilization process comprises includes the following steps: a) a container (15) which can be introduced into, and lodged in, the uterine cavity of the mammal is provided; b) the container (15) is filled with a culture medium, at least one ovocyte of the mammal, and spermatozoa; c) the filled container (15) is inserted into the uterine cavity; d) the container (15) is left for a given length of time to allow fertilization of the ovocyte(s) to take place; e) the contents of the container (15) are released into the uterine cavity. The container may be made from a tube of biodegradable or non-biodegradable material. In the latter case, it is associated with a stiffening device. A biodegradable container (15) filled with gametes and a culture medium is placed in the uterine cavity using an implantation device (20) which is then withdrawn from the mammal's genital tract.
