Abstract
A medical device for regulating fluid flow within one or more lungs of a patient is disclosed. The medical device includes an elongate tubular member, a first extension, a second extension, and a valve member. The elongate tubular member includes a first plurality of channels extending between a proximal and distal ends. The first and second extensions defines a second and third plurality of channels, respectively, each extending from the distal end of the elongate tubular member and configured for placement in a first and second passageway of a lung. The valve member operably couples to the elongate tubular member and is configured to transition between a first position and a second position. The valve member prevents fluid flow to first set of the first plurality of channels in the first position and prevents fluid flow to second set of the first plurality of channels in the second position.
