Embodiment Construction

[0037] Such as figure 1 As shown, the retrievable intrauterine system first comprises a housing 10 intended to be placed in the uterus.

[0038] This housing 10 is intended to be placed in the uterine cavity for a period of time, between a few hours and a few days, to observe the pre-implantation development of the embryo in vivo.

[0039] For this purpose, the housing 10 is adapted to contain embryos, male and / or female gametes, fertilized oocytes, unfertilized eggs or a combination of these different elements.

[0040] The housing 10 may be made of silicone and is provided in its wall with a series of perforations 11 to allow interaction between the interior of the housing and the external culture medium in which the housing 10 is placed, that is to say the uterine culture medium .

[0041] Such as figure 1 As clearly shown in , the housing 10 has an elongated shape along the axis X.

[0042] In this embodiment, housing 10 comprises an elongated cylindrical tube.

Abstract

The invention relates to a recoverable intra-uterine system comprises a housing (1) capable of containing one or a plurality of elements selected from among the group comprising an embryo, male and / or female gametes, a fertilized oocyte, an unfertilized ovum and a combination of these elements, the housing (10) having along an axis (X) a distal end (12) and a proximal end (13), and a device (20) for holding the recoverable intra-uterine device in the uterus. The holding device (20) is arranged at the proximal end (13) of the housing (10) and includes at least one holding arm (23) in the uterine cavity capable of taking at least two positions: - one free position in which at least one holding arm (23) is separated from the axis (X); and - a retracted position in which at least one holding arm (23) is substantially parallel to the axis (X). Use in medically assisted reproduction techniques.

Description

technical field [0001] The present invention relates to a retrievable intrauterine system. [0002] It has to do with stabilizing and holding the retrievable intrauterine system in place during medically assisted reproduction. Background technique [0003] It has been known for several years that intrauterine systems can be implanted and retrieved non-invasively. [0004] Collectively, these systems can be divided into three main families according to their indications or their mode of action. Devices with anti-pregnancy indications, such as intrauterine devices (IUDs) for contraception, represent the vast majority of cases and constitute the first category. [0005] The second category consists of capsules filled with therapeutic substances and placed in the uterine cavity for diffusion and action on the organism. [0006] Finally, the third category includes intrauterine devices used to assist living organisms during medically assisted reproduction. Thus, the intrauter...
