Methods, systems, and kits for lung volume reduction
First Claim
1. A method for lung volume reduction, said method comprising:
- introducing an access catheter to a patient'"'"'s lungs;
isolating a lung tissue segment using the access catheter;
determining a disease-related parameter within the isolated segment using the access catheter,introducing a sealing catheter to the patient'"'"'s lungs; and
sealing an air passage which opens to the lung tissue segment using the sealing catheter.

Abstract
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.
