Embodiment approach
[0069] As an example, we illustrate with Figure 3 a second embodiment of the invention in which the chamber has a rectangular through-hole 12'.
[0070] The length of the through hole may be between 10-150 μm, preferably 75 μm or longer, or 150 μm or almost equal to the length of the small chamber 11 .
[0071] The small chamber is elongated cylindrical, and the rectangular through-hole 12' extends along the longitudinal direction of the small chamber.
[0072] In this embodiment, said wall comprises rows of through holes 12'
[0073] The pitch of the via holes 12' may be between 20 and 200 µm.
[0074] Thanks to the intrauterine device to which the present invention relates, it is possible to maintain oocytes and / or embryos under a chamber cage and at the same time optimize their interaction with the environment of the uterine cavity.
