US 9,308,078 B2 · Medical device, system, and method for regulating fluid flow in bronchial passageways

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.

Dependent claims

A medical device for regulating fluid flow within one or more lungs of a patient, the medical device comprising:

an elongate member having a proximal end, a distal end, and a plurality of channels extending therebetween;
a first extension extending from the distal end of the elongate member and configured for placement in a first passageway of a lung, wherein the first extension defines at least one channel in communication with a first set of the plurality of channels;
a second extension extending from the distal end of the elongate member and configured to be disposed in a second passageway of a lung, wherein the second passageway is different from the first passageway, and wherein the second extension defines at least one channel in communication with a second set of the plurality of channels;
and
a valve member operably coupled to a proximal end portion of the elongate member, wherein the valve member is configured to transition between a first position and a second position, wherein, in the first position, the valve member is configured to prevent fluid flow through the first set of the plurality of channels while the patient inhales, and, in the second position, the valve member is configured to prevent fluid flow through the second set of the plurality of channels while the patient inhales.
