Title (EN) DEVICE FOR MEMBERS FOR CLOSING BODY PASSAGES
(FR) DISPOSITIF D"ORGANES D"OBTURATION DE PASSAGES DANS DES CORPS VIVANTS
Abstract: front page image
(EN)A device for temporarily or permanently closing body passages or cavities in humans and animals and including a member (2) of a material which swells at least 20% by absorbing body fluids and which is substantially inert to body fluids and surrounding tissues, the member (2) being dimensioned so as to be able to be introduced with clearance into the passage or cavity in its unswollen state but to take up the whole cross-section of the passage or cavity in the swollen state and then to be held by pressure against the surrounding walls of the passage or cavity. The device also comprises an element (7) with outer portions (8) which, in the unswollen state of the member, project out from its surface and which are made of a material with such suitable stiffness that the element with said outer portions (8) spreads out, in a yielding manner, towards the surrounding walls of the passage or cavity in such a manner that the element tends to lock the member in its inserted position by pressure against the wall, which ensures holding of the member before it has developed any direct pressure against the surrounding wall through its swelling.
(FR)Un dispositif de fermeture temporaire ou permanente de passages ou cavites de corps humains et animaux, comprenant un organe (2) d"un materiau qui gonfle d"au moins 20% en absorbant des fluides du corps et qui est sensiblement inerte aux fluides du corps et aux tissus environnants, l"organe (2) etant dimensionne pour pouvoir etre introduit aisement dans le passage ou cavite dans son etat non gonfle mais pour remplir toute la section du passage ou cavite dans son etat gonfle et pour s"y maintenir par la pression s"exercant contre les parois du passage ou de la cavite. Le dispositif comprend aussi un element (7) avec des parties externes (8) qui, a l"etat non gonfle de l"organe, se projettent vers l"exterieur a partir de sa surface et qui sont faites en un materiau d"une rigidite appropriee pour que l"element avec lesdites parties externes (8) se dilate vers l"exterieur en s"agrandissant vers les parois du passage ou de la cavite de sorte que l"element tende a verrouiller l"organe dans sa position inseree par pression contre la paroi, ce qui assure le maintien de l"organe avant qu"il n"ait developpe une pression directe contre la paroi en se gonflant.
