In order to enlarge the uterus, inter alia for diagnostic purposes, it is proposed to seal the cervix once a liquid, such as a gel, has been introduced, by means of a sealing stopper, so that liquid does not constantly have to be supplied to the uterus. The sealing stopper is preferably coupled to a gel feed device which may comprise a simple syringe-type structure. This system comprises a non-return valve, as a result of which a gel can only be displaced in the direction of the uterus. In order to ensure that the sealing stopper can be removed, return means, such as a piece of string, are attached thereto.

Selon l'invention, pour agrandir l'utérus, notamment à des fins de diagnostic, il est proposé de fermer le col utérin après introduction d'un liquide, tel qu'un gel, au moyen d'un tampon d'étanchéité qui rend superflu un apport constant de liquide dans l'utérus. Le tampon d'étanchéité est, de préférence, couplé à un dispositif de distribution du gel pouvant comprendre une simple structure de type seringue. Ce système comprend une soupape antiretour qui n'autorise le déplacement du gel que dans la direction de l'utérus. Un moyen d'extraction, tel qu'un bout de ficelle, est fixé au tampon d'étanchéité pour en assurer l'extraction.
