Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation / access catheter.

A heat treatment method for improving fatigue resistance of Al-Cu-Mg alloy comprises: performing high-temperature short-time (505-535 DEG C / 1-25 min) solution hardening treatment on cold-rolled sheets, then performing natural aging at room temperature for 96 h or more. The aluminium alloy capable of being treated by the heat treatment method comprise the components: Cu, Mg, Ti and Al. The technology is simple and reasonable; and through high-temperature short-time solution hardening treatment, the alloy obtains relatively high goss texture components. Because most of crystal faces {111} of crystal grains in the alloy with high goss texture is positioned or close to the direction of the maximum external shearing stress, the reciprocating sliding of dislocation is promoted and a persistent slip band is easy to generate in the alloy, and thus the plasticity induction closure effect of fatigue crack is enhanced and the damage accumulation is reduced, also the crack deflection is promoted, and thus the fatigue crack spreading rate of the alloy is reduced and the fatigue resistance of the alloy is improved.
