主权项

1. A device for selectively controlling air flow, comprising:
an elongate member having a proximal end, a distal end, and a lumen extending therebetween; an inner member disposed about a portion of the lumen, wherein the inner member is configured to transition between a first configuration and a second configuration, wherein, in the first configuration, the portion of the lumen including the inner member defines a first diameter, and, in the second configuration, the portion of the lumen including the inner member defines a second diameter smaller than the first diameter; and an actuation member for transitioning the inner member between the first configuration and the second configuration.
