| 20090241964 | 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. | 10-01-2009 |
| 20100042089 | SELECTIVE LUNG TISSUE ABLATION - Medical methods and systems are provided for effecting lung volume reduction by selectively ablating segments of lung tissue. | 02-18-2010 |
| 20100158795 | METHODS AND SYSTEMS FOR ASSESSING LUNG FUNCTION AND DELIVERING THERAPEUTIC AGENTS - Methods and systems for isolating, assessing and treating lung compartments are disclosed. One or more lung compartments are accessed through an isolation catheter, oxygen rich gas is delivered to the compartments, and blood oxygen or exhaled carbon dioxide are monitored to assess lung compartment function. Diseased lung compartments may be treated using therapeutic agents delivered to the diseased compartments through the isolation catheter. Therapeutic agents include carbon monoxide, radioactive agents, chemotherapeutic agents or angiogenesis inhibitors and angiocidal agents. | 06-24-2010 |
| 20110087122 | MINIMALLY INVASIVE DETERMINATION OF COLLATERAL VENTILATION IN LUNGS - 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. | 04-14-2011 |
