摘要:
Methods and devices are adapted 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.

Delivery system including endoscopes are described. In an embodiment, a delivery system includes a flexible, elongate endoscope extending along a longitudinal axis when the endoscope is straightened and a first lens located on the distal region. The first lens faces a direction transverse to the longitudinal axis. The first lens permits the endoscope to provide an image of anatomical structures that offset from the axis of the endoscope.

摘要:
Methods and systems for lung volume reduction of a patient are described. The methods include implanting a flow control device in a bronchial passageway of the lung. The flow control device regulates fluid flow through the bronchial passageway and includes a valve protector that at least partially surrounds a valve member. The valve protector has sufficient rigidity to maintain the shape of the valve member against compression.
摘要:
Methods and systems for lung volume reduction of a patient are described. The methods include implanting a flow control device in a bronchial passageway of the lung. The flow control device regulates fluid flow through the bronchial passageway. A region of the lung is aspirated distal of the flow control device while the patient is inhaling.
摘要:
Disclosed is a delivery system for insertion into a lung. The delivery system includes an elongate endoscope having a proximal end and a distal end and defining an internal lumen. The endoscope is configured to articulate in one or more directions. The system further includes a catheter that includes an elongate shaft sized to be inserted through the internal lumen of the endoscope. The catheter has a shape that aids in the articulation of the distal end of the endoscope when the catheter is positioned inside the endoscope.
摘要:
A desired fluid flow dynamic to a lung region can be achieved by deploying various combinations of flow control devices and bronchial isolation devices in one or more bronchial passageways that communicate with the lung region. The flow control devices are implanted in channels that are formed in the walls of bronchial passageways of the lung. The flow control devices regulate fluid flow through the channels. The bronchial isolation devices are implanted in lumens of bronchial passageways that communicate with the lung region in order to regulate fluid flow to and from the lung region through the bronchial passageways.
摘要:
Disclosed are methods and devices for treating a patient's lung region. A catheter is deployed into the lung. The catheter is used to apply heat to a targeted lung region wherein the heat affects fluid flow within the targeted lung region.
摘要:
A method of diagnosing collateral ventilation between regions of a lung includes the step of measuring at least one parameter associated with a target lung region while a catheter is positioned in the target lung region. A level of collateral fluid flow into the target lung region is detected based on the at least one parameter.
摘要:
An implantable flow control element is provided which prevents air from entering an isolated portion of a patient's lung. The element may permit air to escape from the isolated portion so that the element acts like a valve. Systems for implanting pulmonary devices are also provided.
