摘要:
Devices systems and methods are disclosed for removing secretions from the lumen of a functional assessment catheter for the lungs. The system comprises a flushing unit configured to deliver a clearing fluid to the lumen of the pulmonary catheter to remove debris, secretions, or moisture from the lumen or sensors.
摘要:
A method of treating snoring and/or OSA in a subject in need of such treatment. The method includes crosslinking proteins of the subject's soft palate tissue or pharynx tissue. The crosslinking can occur by contacting the soft palate or pharynx tissue with a crosslinking reagent. In addition, the crosslinking can occur without heating, contracting or denaturing of the tissue, or any combination thereof.
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:
Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.
摘要:
In some embodiments, an airway assembly may be used in a procedure that requires tracheal intubation. The airway assembly may include a first conduit, a sleeve, and a stent. The first conduit and the sleeve may be relatively flexible, facilitating insertion of the airway assembly in a body lumen (e.g., an air passage way). The first conduit may function to deliver gases (e.g., air) to the body lumen and consequently the patient. The first conduit may be positioned in the sleeve during use. The sleeve may be removably coupled to the first conduit. In certain embodiments, a sleeve may function to inhibit a stent from expanding until desired. In some embodiments, an elongated member may be positionable in the first conduit. The elongated member may be configurable to substantially retain a new shape upon deformation. The stent may be coupled towards the distal end of the first conduit. The stent may function to inhibit the body lumen from collapsing. In certain embodiments, a stent may function to inhibit the body lumen from collapsing without exerting unnecessary outward pressures on the inner surface of the body lumen.

摘要:
Lung conditions are diagnosed and optionally treated using a functional assessment catheter or a functional lung assessment and treatment catheter. A flow restrictive component is initially placed in a bronchus or lung passageway upstream from a diseased lung region. The isolated lung region is then functionally assessed through the catheter, while the flow restrictive component remains in place. If the patient is a good candidate for treatment by occlusive or restrictive treatment techniques, the flow resistive component may be left in place. If the patient is not suitable for such treatment, the flow resistive component may be removed.
摘要:
A minimally invasive lung reduction device which overcomes the disadvantages associated with treating chronic obstructive pulmonary disease by utilizing the phenomenon of collateral ventilation to increase the expiratory flow from a diseased lung. The device also provides a means for assisting in or facilitating pulmonary decompression to compress the diseased area or area of the lung or lungs to a smaller volume.
