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.

The instant invention provides for a pivoting ring that can be used as a seal for an inflatable member. The pivoting ring seal offers a mechanical action which acts to tighten with increasing inflation and / or expansion of an inflatable member. As the inflatable member increases in pressure and / or size, one side of the ring is lifted and pivots around a fulcrum in the middle of the ring seal causing the opposite side of the ring seal to decrease in diameter. The pivot ring causes the opposite part of the seal to tighten about an inner member allowing for a higher-pressure seal. In addition to a higher pressure seal, the working length of the inflatable member can be adjusted by moving the ring along the length of the inflatable member.
