Initial Patient Selection

Patients who meet the following criteria should be evaluated for treatment with endobronchial valves:1-5

  • Breathless despite optimal medical management (mMRC≥2)
  • A confirmed diagnosis of COPD
  • Non-smoking or willing to quit smoking
  • Have an FEV1 ≤50% predicted

Evidence A 2020 Gold Update

GOLD 2020:  Level A Evidence rating affirms that endobronchial valves, like the Zephyr Valve, are a viable, minimally invasive treatment option for severe emphysema, a form of COPD.

Indication and Mechanism of Action

Endobronchial Valves are a new category of treatment for COPD and emphysema. The Zephyr Endobronchial Valve was approved by the FDA in 2018 and is indicated for the bronchoscopic treatment of patients with hyperinflation associated with severe emphysema in regions of the lung that have little to no collateral ventilation (CV). The Zephyr Valve is an implantable device used to occlude all airways feeding the hyperinflated lobe of a lung that is most diseased with emphysema.

These one-way valves comprised of nitinol and silicone allow trapped air to escape during exhalation, but close to prevent air from re-entering during inhalation. This allows atelectasis of the treated lobe and reduction in target lobe volume. The remaining lobes are then able to expand more fully and work more efficiently, reducing pressure on the diaphragm and improving overall lung function and breathing mechanics.1

If you have a patient with COPD that you would like to have evaluated for treatment with the Zephyr Valve,
we can connect you with a Zephyr Valve trained physician.

Complications of the Zephyr Endobronchial Valve treatment can include but are not limited to pneumothorax, worsening of COPD symptoms, hemoptysis, pneumonia, dyspnea and, in rare cases, death.

United States Brief Statement: The Pulmonx Zephyr® Endobronchial Valves are implantable bronchial valves indicated for the bronchoscopic treatment of adult patients with hyperinflation associated with severe emphysema in regions of the lung that have little to no collateral ventilation. The Zephyr Valve is contraindicated for: Patients for whom bronchoscopic procedures are contraindicated; those with evidence of active pulmonary infection; known allergies to Nitinol (nickel-titanium) or its constituent metals (nickel or titanium); known allergies to silicone, or with large bullae encompassing greater than 30% of either lung; Patients who have not quit smoking. The Zephyr Valve should be used with caution and only after careful consideration in treating patients with: Prior lung transplant, LVRS, median sternotomy, or lobectomy; Congestive heart failure or recent myocardial infarction; FEV1 <15% of predicted value. Use is restricted to a trained physician. Prior to use, please reference the Zephyr Endobronchial Valve System Instructions for more information on indications, contraindications, warnings, all precautions, and adverse events.
Caution: Federal law restricts this device to sale by or on the order of a physician.
