A therapeutic system for excising tissue that does not require adherence to medication for patients with asthma and COPD. A treatment system 204 can deliver a coolable ablation assembly that ablates target tissue without damaging non-target tissue. The coolable ablation assembly 208 damages nerve tissue and temporarily or permanently reduces nervous system input. The treatment system treats a wide range of pulmonary symptoms, conditions, and / or diseases including, but not limited to, asthma, COPD, obstructive pulmonary disease, or other diseases that lead to increased resistance to air in the lungs. It can be navigated through the airways, such as the left and right main bronchi, as well as the more distal airways in the lung. [Selection] Figure 8 |
