Brief Summary
Hypothesis: Patients with advanced emphysema with predominance of the disease in areas other than the upper lobes, as determined by high resolution computed tomography (HRCT), could have a positive response to valve treatment.

Interventions
Device: Intra-bronchial valve (Spiration IBV) The IBV is comprised of a Nitnol frame and a polymer membrane, which is held against the airway mucosa by six elastic struts and will expand and contract with airway movement during breathing. The valve is designed to conform to the size and shape of the airways. The frame has 5 flexible anchors that gently secure to the mucosal wall at a controlled depth. Valves are available in 5, 6 and 7mm diameters appropriate for different airways. During a minimally invasive procedure, a catheter is passed through a bronchoscope (a flexible tube passed into the airways through the mouth) to deploy the umbrella-shaped valves into the airways. Only flexible bronchoscopy equipment is required. The valves are designed to be removed if indicated.
Eligibility Criteria
You may qualify if:
- Age 18-80 years
- Ex-smoker with smoking cessation confirmed by exhaled carbon monoxide (CO) levels
- Moderate to severe airflow obstruction FEV1 \<50% Predicted
- Severe dyspnoea - mMRC ≥2
- Hyperinflation - total lung capacity (TLC) ≥100% predicted, RV ≥150% predicted
- SWT ≥75m
- Optimum COPD treatment for at least 6 weeks
- No COPD exacerbation for at least 6 weeks
- Less than 4 admissions for exacerbation in the preceding 12 months
You may not qualify if:
- Patient unable to provide informed consent
- Patient without clear targets for airflow re-distribution
- Total lung CO uptake (TLCO) \<15% predicted and FEV1 \<15% predicted
- pO2 on air \<6.0kPa
- pCO2 on air \>8.0kPa
- Neurological, rheumatological or other cause of exercise limitation
- Other major medical illness, e.g. lung cancer that will limit participation
- Production of purulent sputum more often than not (more than 50% of days)
- Clinically significant bronchiectasis
- Large bulla - more than 1/3 of hemithorax volume (i.e. where bullectomy would be more suitable) on CT scan
- Arrhythmia or cardiovascular disease that poses a risk during procedure or exercise
- Prednisolone dose greater than 15mg a day
