1. A method for treating a lung of a patient, the lung including an airway system having a plurality of branching airways, the method comprising:

  • advancing an implant distally into the airway system while the implant is in a delivery configuration, the implant having an elongate length defining an axis with a lateral profile having a lateral bearing surface transverse to the axis;

    deploying the implant within the airway such that the implant expands laterally from the axis of the implant so as to increase the lateral bearing surface;

    locally compressing lung tissue along the implant by bearing laterally against a luminal surface of the airways with the expanded bearing surface of the implant so that the expansion inhibits penetration of the implant through the airway, and so that tension in other lung tissue of the patient is increased sufficiently to enhance lung function.
