Welcome to the Virtual Tour for Referring Pulmonologist & HCPs

Are You Offering the Full Spectrum of Care to Your Severe COPD/Emphysema Patients?

Zephyr Valves may be able to help 500,000 US patients with severe COPD/Emphysema.1,3

But only 1% of potentially eligible patients have been treated with valves in the last 5 years.*

The Zephyr® Valve delivers durable clinical benefits — without surgery and its associated risks.1-5

Patients experience:1-5

  • Improved health status
  • Improved lung function
  • Increased exercise capacity
  • Reduced breathlessness or dyspnea
  • Reduced gas trapping
  • Improved quality of life

How It Works

How-Zephyr-Valve-Works-COPD-Emphysema

See how the Zephyr Valve treatment is performed as a minimally invasive lung volume reduction procedure. The Zephyr Valve is the first endobronchial valve to receive approval from the FDA for patients with either heterogenous or homogeneous emphysema.

Zephyr Valve Patient Benefits and Risks

Progression of COPD and Emphysema
Staircase+Liberate-01

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

Observe Zephyr Valves as they are placed in the airways of a patient. The valves reduce hyperinflation and gas trapping in patients with severe emphysema. 

Patient Selection for Endobronchial Valves

Key Patient Selection Criteria

  • Confirmed diagnosis of COPD
  • Non-smoking or willing to quit smoking
  • FEV1≤50% predicted
  • Breathless despite optimal medical management (mMRC≥2)
Physician Education & Case Support for BLVR

Making a Referral:

Patients who might benefit from Zephyr Valve therapy include

  • Patients who are not responding to optimal medical management
  • Patients who prefer additional treatment options
BLVR Assessment

Once Referred an Interventional Pulmonologist Will Confirm

  • Diagnosis of severe emphysema
  • Presence of hyperinflation (RV≥175% predicted)
  • Confirmation the target lobe has little to no collateral ventilation

Clinical Evidence

  • 4 RCTs published using Zephyr Valve and Chartis® to preselect patients1-5
  • Published in the New England Journal of Medicine, The Lancet, and The American Journal of Respiratory and Critical Care Medicine1-5,16
  • Statistically significant and clinically meaningful improvements compared to standard of care in multiple trials1-4
  • Treatment success seen in a broad range of primary and secondary endpoints1-5
