摘要： Lung conditions are treated by implanting a flow restrictor in a passageway upstream from a diseased lung segment. The restrictor will create an orifice at the implantation site which inhibits air exchange with the segment to induce controlled atelectasis and/or hypoxia. Controlled atelectasis can induce collapse of the diseased segment with a reduced risk of pneumothorax. Hypoxia can promote gas exchange with non-isolated, healthy regions of the lung even in the absence of lung collapse.

摘要： Minimally invasive methods, systems and devices are provided for qualitatively and quantitatively 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 bronchus of the target compartment. The feeding bronchus is occluded by the catheter and a variety of measurements are taken with the use of the catheter in a manner which is of low risk to the patient. Examples of such measurements include but are not limited to flow rate, volume and pressure. These measurements are used to determine the presence of collateral ventilation and to quantify such collateral ventilation.

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.
摘要翻译：通过在进入肺隔室的气道中密封导管的远端来减少超膨胀的肺隔室的体积。当患者呼气时，空气通过导管中的通道从肺隔间通过。与导管相关联的单向流动元件防止空气在患者吸入时再次进入肺隔室。随着时间的推移，随着空气体积的减小，肺室周围的区域压力会使其崩溃。残余体积减少有效地导致功能性肺容积扩张。任选地，肺隔室可以被密封以便永久地防止空气重新进入肺隔室。本发明还公开了一种在其顶端具有透明阻塞元件的导管，其能够通过观察范围检查肺通道。

摘要： An output assembly is sized for placement in the middle and inner ear, such that removal of bone can be decreased. The output assembly may comprise at least one photo detector, a demultiplexer and an optical array sized to pass through an incision in the eardrum. An input transducer assembly is configured to transmit a multiplexed optical signal to the output assembly. The input assembly can be configured to transmit the multiplexed optical signal through the eardrum, such that tissue removal can be decreased and the device can be placed without removal of bone, for example. The multiplexed optical signal may comprise a pulse width modulated signal so as to decrease the effect of non-linearities of the light source and light detector and provide quality sound to the user.
