Atelectasis refers to the collapse of lung tissues which may affect a part of a lung or the whole lung itself. Usually the alveoli part collapses resulting to impaired gas exchange. Fluid retention in the lungs may also lead to the collapse of some tissues leading to the condition known as atelectasis.
Method for treating an asthma attack
A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.

Devices for maintaining patency of surgically created channels in tissue
ActiveUS20060135984A1Increase duration of patencyLess traumaDiagnosticsSurgical needlesObstructive Pulmonary DiseasesLung tissue
Devices and methods for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease. The methods and devices create channels in lung tissue and maintain the patency of these surgically created channels in tissue. Maintaining the patency of the channels allows air to pass directly out of the lung tissue which facilitates the exchange of oxygen ultimately into the blood and / or decompresses hyper-inflated lungs.

ActiveUS20110118725A1Reduce harmReduce obstructionUltrasound therapySurgical needlesCOPDPartial denervation
A system and method can be used to denervate at least a portion of a bronchial tree. An energy emitter of an instrument is percutaneously delivered to a treatment site and outputs energy to damage nerve tissue of the bronchial tree. The denervation procedure can be performed without damaging non-targeted tissue. Minimally invasive methods can be used to open airways to improve lung function in subjects with COPD, asthma, or the like. Different sections of the bronchial tree can be denervated while leaving airways intact to reduce recovery times.

Endoscopic arterial pumps for treatment of cardiac insufficiency and venous pumps for right-sided cardiac support
Methods for using blood pumps to treat heart failure are disclosed. The pump is mounted on an interior of a stent, and the stent is releasably mounted on a distal end of a catheter. The distal end of the catheter is inserted into a peripheral artery and advanced to position at a region of interest within the descending aorta, the ascending aorta, or the left ventricle. The stent and the pump are released from the catheter, and the pump is activated to increase blood flow downstream of the pump. The pump can also be positioned in the vena cava or used to treat right-sided heart failure following the insertion of an LVAD, or to improve venous return in patients with varicose veins. Non-stent pumps are described for insertion between the pulmonary vein and aorta, and between the vena cava and pulmonary artery designed for use during cardiac surgery.

It generally includes fluidly connecting the lung to an extrapleural airway such as the trachea. In one variation, a conduit is deployed to place the lung and the trachea in fluid communication which allows trapped oxygen-reduced air to pass directly out of the lung and into the trachea. Removing nonfunctional air from the lung tends to improve the gaseous exchange of oxygen into the blood and decompress hyper-inflated lungs. Sealant and biocompatible adhesives may be provided on the exterior of the conduit to prevent side flow, leaks and to otherwise prevent air from entering spaces not intended to receive air such as the pleura space.

Methods and devices for passive residual lung volume reduction and functional lung volume expansion
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.

Devices and methods for testing a pulmonary vein to determine whether or not ablation would be effective in terminating atrial fibrillation. The devices and methods include a catheter having an expandable balloon attached to the distal end of the catheter. The balloon has pores on the distal end of the balloon for administering a fluid into the target pulmonary vein. The fluid inhibits the electrical impulses generated by the target pulmonary vein. Once the electrical impulses of the target pulmonary vein have been inhibited it can be determined whether or not the atrial fibrillation continues to occur. If the atrial fibrillation has been eliminated, then ablation or other therapy is appropriate. Thus, the devices and methods limit unnecessary treatment of a pulmonary vein.
