Publication number: 20080154088Abstract: A method and apparatus for safer and more effective deep trans-cervical intra-uterine artificial insemination (AI) is provided. Such a deep AI catheter causes minimal discomfort and risk of trauma, and does not require the services of a highly trained AI professional. First, a catheter is inserted into the cervical tract of the animal. A membrane, initially positioned inside a tube section of the catheter, is then extended from an opening in the tube and into the tract under pressure. The membrane extends into the tract without friction thereby reducing the discomfort and the risk of trauma or injury to the animal. When the membrane is fully extended into the tract, pressure causes the tip of the membrane to open thereby releasing the AI fluid and depositing the genetic material suspended in the fluid into the reproductive tract.Type: ApplicationFiled: March 11, 2008Publication date: June 26, 2008Applicant: PATHWAY TECHNOLOGIES, LLCInventors: Mark E.

Patent number: 6149579Abstract: A semen storage container containing the semen of a male pig is sealed with a stopper having a cone-shape vomiting portion whose point is closed at one end when the semen is used for artificial insemination, a predetermined portion of the cone-shape vomiting portion of the stopper is cut inserted into an insertion tube which is then inserted into the womb of female pig, thereby easily and cleanly carrying out artificial insemination. A window for confirming the amount of semen stored is added to the semen storage pack who se exterior is shading-printed to block a harmful ray of light such as direct ray of light, protecting the semen from deterioration.Type: GrantFiled: November 30, 1998Date of Patent: November 21, 2000Inventor: Won Ku Lee

Patent number: 6117068Abstract: An artificial insemination system and its use requires a sheath which has a first lumen for receiving and holding an endoscope, and a second lumen through which semen can be injected into the uterus of the animal to be inseminated. Additionally, the sheath includes a blunt guide probe which extends distally from the distal end of the sheath. A window covers the distal end of the first lumen so that the user can use the endoscope to view the guide probe and the general area surrounding the guide probe. When using the system, the endoscope is initially inserted into the first lumen of the sheath. The combination of sheath and endoscope are then inserted into the vagina of the animal and, using the endoscope, the guide probe is position at the cervical os. While continuing to view the guide probe with the endoscope, the guide probe is directed through the cervix until the distal end of the second lumen is positioned in the uterus.Type: GrantFiled: October 19, 1995Date of Patent: September 12, 2000Assignee: Elite Genetics, IncInventors: Dennis D. Gourley, Debra N. Gourley, David D. Kloostra, George H. Middle, Algis R. Banys, Allen G. Freiman

Patent number: 6071689Abstract: Improved insemination systems particularly adapted to use for sex-selected sperm sorting include systems which achieve superovulation and then multiple embryo production with sexed embryos. These systems combine with other techniques, including techniques for enhanced sheath fluid and other strategies which minimize stress on the sperm cells, and, potentially, a 2.9 percent sodium citrate sheath solution for bovine species and a hepes bovine gamete media for equine species. Improved collection systems and techniques for the process are described so that commercial application of sperms samples as well as the resulting animals may be achieved.Type: GrantFiled: January 29, 1998Date of Patent: June 6, 2000Assignee: XY, Inc.Inventors: George Seidel, Lisa Herickhoff, John Schenk

Patent number: 6071231Abstract: An artificial insemination device is formed by attaching a semen filled straw or tube to one end of a pipette to which a syringe is attached at the other end. An anchorable tip is attached to the other end of the semen filled tube. The semen filled tube is attached by forming tapered bores in the pipette and anchorable tip so that semen filled tubes of various diameters can be press fit into the tapered bores. The pipette-tube-tip assembly is inserted into the animal's vagina using a speculum until the tip enters the cervix, and a seal is formed between the tip and cervix by inflating an attached balloon. The syringe, which contains a diluent fluid, is pushed to force semen and diluent fluid out through ejection port(s) in the tip into the animal's uterus. Optimum amounts of semen and diluent fluid can be delivered to various sized animals.Type: GrantFiled: July 11, 1997Date of Patent: June 6, 2000Inventors: Marco Antonio Hidalgo Mendoza, William A.

Patent number: 6059716Abstract: An artificial insemination device for private use which is capable of allowing unskilled persons to achieve an artificial insemination of livestock such as cattle, horses, and deer, etc. in a simple and easy manner using frozen semen of those livestock. The device includes an in-vagina insert unit inserted into the vagina of a female to be inseminated upon injecting semen into the female, and a semen injection unit inserted into the womb canal of the female through the in-vagina insert unit upon injecting semen into the female. The in-vagina insert unit includes a hollow insert body, and an insert tube slidably fitted at its rear end in a front end of the insert body in such a manner that its length protruded from the insert body is adjustable in accordance with the depth of the vagina of the female. The semen injection unit includes an elongated semen injection tube connected at a rear end thereof to an injector, and a guide/nozzle member separably coupled to a front end of the semen injection tube.Type: GrantFiled: December 9, 1998Date of Patent: May 9, 2000Assignee: Rural Development AdministrationInventors: Myeung-Sik Lee, Soo-Bong Park, Won-Kyong Chang, Jin-Ki Park, Yong-Yun Park

Patent number: 5967368Abstract: A connecting device for connecting a container (1) consisting of a sealed flexible bag (3) to an external duct (2) that includes a tube (4) with a connecting opening (5). A rigid tubular coupling (6) is loosely arranged within the flexible container (1) and comprises a frusto-conical projection (7) sized in such a way that it may be force-fitted into the opening (5). A user grasps the coupling (6) and places it against the inner surface of the bag (3) while placing the opening (5) of the external duct (2) against the outer surface of the bag (3), then axially presses on the coupling (6) so that it perforates the bag (3) and sealingly engages the opening (5). The fluid in the container (1) can then flow through the coupling (6) into the external duct (2).Type: GrantFiled: April 17, 1998Date of Patent: October 19, 1999Inventor: Bernard Guillermier
