Embodiment Construction

[0050] first reference Figures 1 to 3 Exemplary embodiments of retrievable intrauterine devices are described.

[0051] In general, a retrievable intrauterine device includes a housing 10 for containing various items employed in medically assisted reproductive procedures.

[0052] In particular, the housing 10 is configured to accommodate different items, such as male and / or female gametes, unfertilized eggs or fertilized oocytes, or one or more embryos, depending on the state of progress of the fertilization process.

[0053] It will be noted that the retrievable intrauterine device is configured to accommodate one or the other of these items during the duration of the fertilization procedure, depending on the state of the procedure.

[0054] The housing 10 is special in that it comprises a double wall formed by an inner wall 11 and an outer wall 12 .

[0055] The inner wall 11 is formed from a biocompatible polymer.

[0056] Since the internal wall 11 is adapted to form ...

Abstract

The invention relates to a retrievable intrauterine device which includes a recess (10) suitable for containing one or more elements selected from the group that includes an embryo, male and / or femalegametes, a fertilised oocyte, a non-fertilised ovule and a combination of said elements. The recess (10) includes an inner wall (11) made of a biocompatible polymer, the inner wall (11) including atleast one perforated portion (13a, 13b) having perforations with dimensions of between 1 [mu]m and 10 [mu]m, and an outer wall (12) covering the inner wall (11), the outer wall (12) being made of a biocompatible silicone elastomer and including at least one opening (14a, 14b) opposite said at least one perforated portion (13a, 13b) of the inner wall (11). The use of the device relates to the pre-implantation development of gametes and / or embryos.

Description

technical field [0001] The present invention relates to a retrievable intrauterine device, in particular for the temporary placement of gametes and / or embryos in the uterus. [0002] The present invention relates generally to the field of in vivo and intrauterine conception in assisted reproductive methods employing fertilization and / or preimplantation development techniques. Background technique [0003] Intrauterine systems that can be implanted and retrieved through a bodily passage have been known for many years. [0004] Thus, intrauterine devices for use in the in vivo assistance of medically assisted reproductive procedures as described in document WO 03 / 011200 are known. [0005] Such a device is suitable for placement in the uterine cavity for a period of between hours and days and enables pre-implantation development of the embryo. [0006] The intrauterine device comprises a housing adapted to contain items to be enclosed in the device, such as embryos, male and...
