摘要： Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region. An exemplary flow control device is configured to block fluid flow in the inspiratory direction and the expiratory direction at normal breathing pressures and allow fluid flow in the expiratory direction at higher than normal breathing pressures.

摘要： Devices, methods, and systems are provided for sealing a lung region. The target lung compartment is accessed and isolated via an isolation catheter. Fluid is delivered into the target lung compartment such that the target compartment is pressurized and the fluid flows through the collateral flow channel. A sealing agent is injected into the isolated lung compartment such that the agent is carried by the fluid to the collateral flow channel, thereby sealing the collateral flow channel. Variables of air flow may be measured or analyzed prior to injection of the sealing agent, or the sealing agent may be introduced into the region after a suitable time has elapsed.

摘要： Methods and systems for accessing and diagnosing diseased lung compartments are disclosed. Methods may comprise introducing a diagnostic catheter with an occluding member at its distal end into a lung segment; inflating the occluding member to isolate the lung compartment; and performing a diagnostic procedure with the catheter. The proximal end of the diagnostic catheter is configured to be attached to a console. Methods may also include allowing air to enter the lung compartment through the passage in the catheter while the patient is inhaling and blocking air from being expelled from the lung compartment through the catheter passage while the patient is exhaling by using a one-way flow element adapted to be disposed within or in-line with the passage of the catheter so that flow in a proximal-to-distal direction is allowed and flow in a distal-to-proximal direction is inhibited or prevented.

摘要： Minimally invasive methods, systems and devices are provided for assessing collateral ventilation in the lungs. In particular, collateral ventilation of a target compartment within a lung of a patient is assessed by advancement of a catheter through the tracheobronchial tree to a feeding airway of the target compartment. The feeding airway is occluded by the catheter and the opening and closing of a one-way valve coupled with the catheter is observed. If the valve ceases opening and closing over time, this may indicate that significant collateral ventilation into the target compartment is absent. If the valve continues to open and close over time, significant collateral ventilation into the compartment may be present. Based on the collateral ventilation assessment, a treatment plan may be generated.
