Saturn 5™ Laser System
Using Saturn 5 Active™, you will find the following procedures are almost effortless and can be performed quickly and accurately. These procedures may require difficult embryo manipulation when performed using fixed lasers.
The directional laser means that accurate ablations can be made without the need to hold the embryo, making it very quick and accurate.
Blastomere biopsy (for PGD/PGS) is a technique that is performed at the six to eight cell stage (about 72 hours or day 3 of embryo culture). One or two cells, or blastomeres, are separated from the rest of the embryo for testing. A hole is made, often with a laser, eg the Saturn 5™ Laser, in the zona pellucida which is the shell surrounding the developing embryo and the cell/s are gently removed. The developing embryo is then placed back into the culture media and returned to the incubator where it can resume its normal growth and development.
Trophectoderm / Day5 Biopsy
Trophectoderm biopsy is a relatively new technique often used for the genetic screening of embryos.The technique involves taking cells from the outer layer of an embryo (that will form the placenta not the fetus) at day 5 of development. A blastocyst has 200-300 cells. Some advantages are that, compared to the traditional method for biopsy (at the cleavage stage – day 3) more cells can be taken from the embryo to be analysed for the genetic condition, leading to a more reliable diagnosis and a smaller percentage of the embryonic mass taken from the cells which are not destined to form the fetus.
