1. A device for selectively controlling air flow in a patient, the device comprising:
- a 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;
an actuation member for transitioning the inner member between the first configuration and the second configuration; and
a controller configured to send an output to the actuation member, the controller being configured to;
increase a rate at which the inner member transitions between the first configuration and the second configuration when a frequency of inhalation and exhalation of a lung of the patient increases; and
decrease the rate at which the inner member transitions between the first configuration and the second configuration when the frequency of inhalation and exhalation in the lung decreases.

Abstract
Provided are devices, systems and methods of selectively controlling air flow into one or more section of a patient'"'"'s lungs. In particular, the devices may be valve devices having an inner lumen configured to transition between a first diameter and a second diameter smaller than the first diameter to control the airflow through the valve.

8. A system for controlling air flow in parts of a lung, the system comprising:
-
a plurality of valve devices; and a controller coupled to the plurality of valve devices configured to control energy supplied to the plurality of valve devices, wherein each of the plurality of valve devices comprises; 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, wherein the actuation member is disposed on a portion of the inner member, wherein the controller is configured to transition each of the plurality of valve devices between the first configuration and the second configuration based on a detected breathing cycle of the lung, wherein the plurality of valve devices includes a first valve device configured to be placed in a first airway of the lung, and a second valve device configured to be placed in a second airway of the lung that is different than the first airway of the lung, and wherein, over a period of one day, the controller is configured to maintain the first valve device in the first configuration for a higher percentage of time than the second valve device is maintained in the first configuration based on respective locations of the first airway and the second airway in the lung, and based on an ability of the lung to expand in portions adjacent to the first airway and the second airway. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A system for controlling air flow in a lung, the system comprising:
-
a first valve device configured to be placed in a first airway of the lung, and a second valve device configured to be placed in a second airway of the lung that is different than the first airway of the lung; an energy supply including an inductive coil configured to deliver energy to each of the first valve device and the second valve device; a controller coupled to the first valve device and the second valve device, the controller being configured to control the energy delivered to the first valve device and the second valve device by the energy supply; a wireless receiver operatively coupled to the controller; a breathing sensor including an electrically conductive element, wherein the breathing sensor is configured to detect the breathing cycle of a patient while coupled to a thorax of the patient; and a wireless output operatively coupled to the breathing sensor, wherein the wireless output is configured to send a wireless signal indicative of the detected breathing cycle to the wireless receiver; wherein the first valve device and the second valve device each includes; a 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, wherein the actuation member is disposed on a portion of the inner member, wherein the controller is configured to transition each of the first valve device and the second valve device between the first configuration and the second configuration based on the detected breathing cycle by changing a frequency of the energy delivered from the energy supply to the first valve device and the second valve device. - View Dependent Claims (19)
