Title (EN) EXPANDABLE DEVICE AND METHODS FOR USE
(FR) DISPOSITIF EXTENSIBLE ET PROCEDES POUR L'UTILISER
Abstract:
(EN) Systems and methods for directionally controlling expansion and for radioscopic visualization of the positioning of an expandable device are described. One such device includes an expandable body comprising a first wall portion (53) and a second wall portion (55). The first wall portion comprises a high elasticity material (54). The second wall portion comprises a material having an elasticity lower (56) than the elasticity of the first wall portion. When the body is expanded, expansion of the second wall portion is constrained more than expansion of the first wall portion. Expansion of the body is directed outwardly from the high elasticity first wall portion (Fig 2). Such a device is useful for providing cavities an interior body regions. A radiopaque marking pattern (59) can be configured to allow for visualizing radioscopically the orientation and movement of the expandable body m unexpended and expanded states in an interior body region
(FR) La présente invention concerne des systèmes et des procédés pour commander une direction d'extension et pour une visualisation radioscopique du positionnement d'un dispositif extensible. Un tel dispositif comprend un corps extensible qui présente une première partie de paroi et une seconde partie de paroi. La première partie de paroi comprend une matière à haute élasticité. La seconde partie de paroi comprend une matière qui présente une élasticité inférieure à l'élasticité de la première partie de paroi. Lorsque le corps est étendu, l'extension de la seconde partie de paroi est plus contrainte que l'extension de la première partie de paroi. L'extension du corps est orientée vers l'extérieur en raison de la grande élasticité de la première partie de paroi. Un tel dispositif est utilisé pour ménager des cavités dans des régions internes du corps. Un modèle de marquage radio-opaque peut être conçu pour permettre une visualisation radioscopique de l'orientation et du déplacement du corps extensible dans des états non étendus et étendus dans une région interne du corps.
