Methods and devices for obstructing and aspirating lung tissue segments
InactiveUS6527761B1Reduce the possibilityIncrease anchorageMedical devicesMedical applicatorsLung volumesObstructive Pulmonary Diseases
Methods, systems, devices and kits for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions using and comprising minimally invasive instruments introduced through the mouth (endotracheally) to isolate a target lung tissue segment from other regions of the lung and reduce lung volume. Isolation is achieved by deploying an obstructive device in a lung passageway leading to the target lung tissue segment. Once the obstructive device is anchored in place, the segment can be aspirated through the device. This may be achieved by a number of methods, including coupling an aspiration catheter to an inlet port on the obstruction device and aspirating through the port. Or, providing the port with a valve which allows outflow of gas from the isolated lung tissue segment during expiration of the respiratory cycle but prevents inflow of air during inspiration. In addition, a number of other methods may be used. The obstructive device may remain as an implant, to maintain isolation and optionally allow subsequent aspiration, or the device maybe removed at any time.

A percutaneous single-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. A pneumostomy instrument is introduced percutaneously through the thoracic wall, parietal membrane, visceral membrane and into the parenchymal tissue of the lung. The pneumostomy instrument crosses the pleural cavity between the parietal membrane and visceral membrane there being no pleurodesis between the membranes prior to passage of the pneumostomy instrument. A pneumoplasty device at the distal end of the pneumostomy instrument displaces and engages the parenchymal tissue of the lung and the pneumostomy instrument is used to secure the lung and visceral membrane in contact with the parietal membrane and chest wall. The pneumostomy instrument is left in place while a pneumostoma tract heals and pleurodesis occurs between the pleural membranes surrounding the pneumostomy instrument.

Prediction of exacerbations for COPD patients
InactiveUS20140221782A1Inhibit deteriorationAvoid hospitalizationHealth-index calculationMedical automated diagnosisProper treatmentOxygen meters
The invention provides a method for estimating if a patient suffering from Chronic Obstructive Pulmonary Disease (COPD) is approaching an exacerbation. Data with connected data indicative of levels of blood oxygen saturation obtained from the patient and their respective time of measurements are received, and a processor executes an algorithm involving: 1) calculating a statistical measure, e.g. a regression, of the level of blood oxygen saturation data taking into account available data within a time window with a limited length back in time, e.g. 30 days back in time, and 2) estimating if the patient is approaching an exacerbation by comparing a value obtained from said statistical measure to a reference value. Finally, an output indicative of a result of said estimation is generated. The method can ensure that COPD patients, e.g. in tele homecare, are properly treated before suffering from a severe exacerbation that could necessitate hospitalization. The COPD patient can easily measure blood oxygen saturation with an oxygen meter, and the algorithm can be executed on a mobile phone, a PC, on a server in contact with the patient via the interne, or on a dedicated oxygen meter device.
