Disclosed is a flow control device (610) for a bronchial passageway (15). The device can include a valve member (620) that regulates fluid flow through the flow control device (610), a frame (615) coupled to the valve member (620), and a membrane (625) attached to the frame. At least a portion of the flow control device (610) forms a seal with the interior wall of the bronchial passageway (15) when the flow control device (610) is implanted in the bronchial passageway (15). The membrane (625) forms a fluid pathway from the seal into the valve member (620) to direct fluid flowing through the bronchial passageway (15) into the valve member (610).

La présente invention concerne un dispositif de régulation de débit pour passage bronchique. Le dispositif de l'invention peut comprendre un organe soupape qui régule le débit fluidique à travers le dispositif de régulation de débit, un cadre couplé à l'organe soupape, et une membrane attachée au cadre. Au moins une partie du dispositif de régulation de débit forme un joint d'étanchéité avec la paroi intérieure du passage bronchique lorsque le dispositif de régulation de débit est implanté dans le passage bronchique. La membrane forme, depuis le joint d'étanchéité jusque dans l'organe soupape, un passage fluidique qui permet de diriger le fluide s'écoulant à travers le passage bronchique jusque dans l'organe soupape.
