Definitions

  • the following invention as it is expressed in the title of the present specification, relates to a post-cervical insemination catheter with multiple deposition zones, by means of which it is allowed to deposit the semen at two or more different points inside the genital tract of the female to be inseminated.
  • the catheter object of the present invention is defined as a one-piece tubular body fitted at one end (distal) with a spherical-shaped body provided with, at least, a hole being an extension of the axial hole of the tubular body, the end of which is introduced into the reproductive apparatus of the animal to be inseminated.
  • the essential object of the catheter is the incorporation of some additional holes at, at least, one point or area of the tubular body of the catheter, allowing obtaining a semen deposition at different points of the genital tract, that is, at a different depth of the genital tract.
  • the diameter of the holes may vary depending on the ratio of the dose of semen that we wish to deposit at each depth level inside the genital tract of the female.
  • a post-cervical insemination catheter with multiple deposition zones is described, applicable for the artificial insemination of different animal species: ovine, equine or bovine, and being especially applicable for the porcine specie.
  • the transcervical insemination requires a much higher number of spermatozoons than the deep intrauterine (1000-1500 millions vs. 50-150 millions), while with the deep intrauterine unusually low prolificities and even suppression of pregnancy by unilateral fertilization have been observed.
  • the post-cervical insemination catheter is defined by a tubular body having, at least, a hole for releasing the seminal deposition at the distal end thereof and, at least, a hole for releasing the seminal deposition at an Intermediate point or area of the tubular body.
  • the post-cervical insemination catheter may have, at least, a hole for releasing the seminal deposition, between the holes for releasing the seminal deposition, provided at the distal end thereof and at the intermediate area of the tubular body,
  • the catheter may have a variable number of holes for releasing a dose of semen, such that said dose of semen is dispensed at a larger distance of the catheter and the probability of reaching the object of fertilization to be higher.
  • the catheter being presented has as an object that the hole or holes for releasing the seminal deposition at the distal end thereof Is/are located at a uterine horn and the hole or holes for releasing the seminal deposition provided at an intermediate point or area of the tubular body correspond to the uterus and/or cervix.
  • the size or number of the holes will be proportional to the percentage of the dose of semen to be deposited at each of said areas (uterine horn and/or uterus and/or cervix), the end and intermediate holes for releasing a dose of semen being able to have different diameters among themselves or else identical diameters, according to the amount of the dose of semen which one is interested on depositing by each one of said holes.
  • the catheter will be able to be introduced without guide catheter or with guide catheter.
  • the possible holes made between the holes of the distal end and the intermediate holes could be located at any area thereof.
  • the post-cervical insemination catheter 1 for multiple deposition is defined as a one-piece element formed by a flexible elongated tubular body 2, fitted at one end (the internal end in the insemination) with a rounded body provided with, at least, a hole forming an axial extension of the tubular body.
  • the catheter being presented has the object of locating the hole or holes 3 for releasing the seminal deposition at the distal end thereof 4 at a uterine horn 7 and locating the hole or holes 5 for releasing the seminal deposition at an intermediate point or area 6 of the tubular body 2 in the uterus 8.
  • the holes 3 and 5 for releasing a dose of semen may have other holes 9 allowing the deposition of the dose of semen at areas among the cervix, the uterus and the uterine horn.
  • the size and number of the holes 3 and 5 will be proportional to the percentage of the dose of semen to be deposited at each one of said areas 4 and 6.
  • the catheter 1 Given the constitution of the catheter 1 it will be able to be introduced without guide catheter or with guide catheter.
  • the essential object of the catheter 1 is having one or more additional holes in the tubular body at a variable distance from the mentioned distal hole.
  • the diameter of the holes made on the catheter could all of them be identical, different, or else could be some of them identical among themselves and others different, in order to adapt according to the volume of semen wanting to deposit at the different locations along the genital tract.
  • the main novelty of the new catheter with respect to those already available in the market is that it offers the possibility of carrying out post-cervical insemination at two or more depth levels In the female reproductive apparatus.
  • distal hole or holes will allow depositing a specific volume of semen in the body of the uterus and/or cervix, in the utero-tubal junction or inside the uterine horn, the remaining holes will allow depositing a variable volume of semen at cervical or post-cervical level.
  • the new insemination system shows the same advantages as the post-cervical insemination systems, with regard to the place of deposition, the reduction in the incidence of reflux during the insemination and reproductive results, but shows additional advantages with regard to the rest of intrauterine systems.
  • the new catheter will considerably reduce the number of spermatozoons used and, as a result, the costs of the insemination process with the resulting economic benefit.
  • This reduction on the number of spermatozoons used is due to two basic facts derived from the existence of two or more semen deposition points:
  • the deep intrauterine insemination reduces the prolificity as a consequence of the solely fertilization of the ovocytes located in the uterine horn wherein the catheter is introduced.
  • the new catheter object of the invention prevents this problem since by allowing depositing a part of the dose of semen at a portion of the reproductive tract preceding the uterine horn simultaneously to the deep intrauterine insemination, with the post-cervical insemination we increase the possibility of fertilization in the uterine tube through which the catheter is introduced, while the spermatozoons deposited at the portion of the reproductive tract preceding the uterine body, will be able to ascend until reaching the oviduct where the fertilization by both uterine horns occurs.
