Patent

CA 2479805

An intra-bronchial device (100) may be placed and anchored in an air passageway (50) of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member (110) that prevents air from being inhaled into the lung portion, and an anchor (112) that anchors the obstruction device (110) within the air passageway. The anchor (112) may piercingly engage the air passageway wall. The anchor (112) may be releasable from the air passageway wall. The anchor (112) may be releasable from the air passageway for removal of the obstructing member (110). The anchor (112) may be releasable by collapsing a portion of the obstructing member (110), or by drawing the obstructing member toward the larynx. The obstructing member (110) may be a one-way valve.

L'invention concerne un dispositif interbronchique (100) que l'on peut déplacer et ancrer dans un passage d'air (50) d'un patient afin d'écraser une partie pulmonaire associée au passage d'air. Le dispositif comporte un élément d'obstruction (110) évitant que l'air ne soit inhalé dans la partie pulmonaire et un élément d'ancrage (112) qui ancre le dispositif d'obstruction (110) dans le passage d'air. L'élément d'ancrage (112) peut s'emboîter par perçage dans la paroi du passage d'air. L'élément d'ancrage (112) peut être retiré de la paroi du passage d'air et retiré du passage d'air en vue du retrait de l'élément d'obstruction (110). L'élément d'ancrage (112) peut être retiré par écrasement d'une partie de l'élément d'obstruction (110) ou par retrait de l'élément d'obstruction en direction du larynx. L'élément d'obstruction (110) peut être une soupape unidirectionnelle.
