Embodiment approach

[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.

[0075] Of course, many variations can also be introduced to the previously described embodiments without exceeding the scope of the invention.

Abstract

A recoverable intra-uterine device comprising a housing containing one or several elements selected from a group containing an embryo, male and / or female gametes, a fertilised oocyte, an unfertilised egg and the combination thereof, wherein said housing is provided with a wall made of a biocompatible material. The wall is provided with a series of perforations whose size is sufficient in order to bring the intra-uterine medium into a cellular contact with the housing and to keep the elements therein. The inventive device is provided with a system for loading and unloading one or several elements selected from the group containing an embryo, male and / or female gametes, a fertilised oocyte, an unfertilised egg and the combination thereof.

Description

technical field [0001] The present invention relates to a retrievable intrauterine device, especially for the implantation of gametes or embryos in the uterus. Background technique [0002] The present invention relates to general methods of in vivo and intrauterine fertilization in assisted reproductive methods following published culture techniques and / or pre-implantation development. [0003] A retrievable intrauterine device as described in document WO3 / 011200 has been recognized. [0004] The intrauterine device comprises a chamber for containing a component of interest, such as embryos, female or male gametes, fertilized or unfertilized eggs, encapsulated within the device. [0005] This encapsulation technology allows fertilization and embryo development in a capsule placed in the uterus. [0006] The advantages of this technique are: overcoming several problems caused by in vitro culture; and pre-transfer developmental gametes and / or embryos can be placed during th...
