Systems and methods for mechanical displacement of an esophagus

An example assembly for use with a vacuum system and an esophageal positioning device esophageal positioning device includes an introducer, in which the esophageal positioning device includes a first segment and a second segment. The second segment is pivotally connected to the first segment. A gap portion of an outer tube of the introducer is defined along a longitudinal axis between a tube tip of the introducer and the distal end of the second segment of the esophageal positioning device when the esophageal positioning device is disposed within the introducer. The gap portion defines one or more radial vacuum holes.

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.
