The catheter assembly may include an inner catheter member having an inner catheter lumen and an outer catheter member having an outer catheter lumen, where the inner catheter member is disposed longitudinally and coaxially through at least a lengthwise portion of the outer catheter lumen, a distal end portion of the outer catheter includes an atraumatically-shaped disruptable seal-which seal includes at least a pair of overlapping slits that extend at least partially through an internal distal end wall portion of the outer catheter-and where a distal end portion of the inner catheter includes a wedging structure configured to at least partially sealingly contact an inner circumference of a passage in a lower portion of a patient lung.
