An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and recollapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by recollapsing the device and pulling the device proximally through a catheter.

Systems and devices for minimally invasively treating an air leak in a lung comprise the steps of detecting an air leak in a lung; locating an airway in fluid communication with the air leak, introducing a bronchoscope into a patient's airway to a position adjacent the target section and occluding an airway upstream of the air leak for a period of time. The airway occlusion device is preferably removed after the air leak has substantially permanently healed. The occluding device may be a one-way valve. The occluding device may also comprise strut members and anchors that penetrate an airway wall.

An apparatus and method deploy a self-expandable bronchial obstruction device in an air passageway. The apparatus includes a catheter configured to be passed down the trachea. The apparatus further includes a capsule for housing the self-expandable bronchial obstruction device in a sterile environment. The capsule is configured to be advanced down the catheter. The capsule further includes a tubular extension. The capsule has a breakable seam so as to release the bronchial obstruction device in the air passageway upon a proximal force being exerted upon the bronchial obstruction device. The method includes guiding a conduit down a trachea into the air passageway. The method further includes advancing a capsule having a bronchial device therein down an internal lumen of the conduit into the air passageway. The method further includes releasing the bronchial device from the capsule. The method further includes deploying the bronchial device into the air passageway.
摘要:
The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment. The invention further discloses a catheter with a transparent occlusion element at its tip that enables examination of the lung passageway through a viewing scope.

摘要:
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.
摘要:
A lung volume reduction system is disclosed comprising an implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to bend the lung airway. The invention also discloses a method of bending a lung airway of a patient comprising inserting a device into the airway in a delivery configuration and bending the device into a deployed configuration, thereby bending the airway.
摘要:
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.
摘要:
An intra-bronchial device may be placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member that prevents air from being inhaled into the lung portion, and an anchor that anchors the obstruction device within the air passageway. The anchor may piercingly engage the air passageway wall. The anchor may be releasable from the air passageway for removal of the obstructing member. The anchor may be releasable by collapsing a portion of the obstructing member, or by drawing the obstructing member toward the larynx. The obstructing member may be a one-way valve.
