1. A device for selecting a size of a pulmonary implant configured to be implanted in an airway in a human or animal subject, the device comprising:
a flexible catheter body having a proximal end, a distal end, and a longitudinal axis;
a first fixed length flexible sizing element and a second fixed length flexible sizing element disposed along and extending approximately orthogonally relative to the longitudinal axis from the flexible catheter body, wherein the first and second fixed length flexible sizing elements have different heights from one another; and
a depth marker disposed along the flexible catheter body at a distance from the distal end, the depth marker configured to indicate a pulmonary implant is too long for an airway if the depth marker is proximal to a proximal end of the airway and configured to indicate the pulmonary implant fits the airway if the depth marker is located within the airway when the distal end of the flexible catheter body contacts a branch of the airway.
