Zephyr® Endobronchial Valve

The Zephyr® Endobronchial Valve is an endoscopic lung volume reduction therapy that has been proven to significantly improve lung function, exercise capacity and quality of life for emphysema patients across four randomized, controlled clinical trials and in 12,000 patients worldwide.

In combination with its diagnostic companion products, it uniquely offers a prospectively proven method for predicting responders. It is also designed to be removable, preserving future treatment options for patients.

With the valves, we can treat patients who did not have any treatment options before. Dr. med. Dirk-Jan Slebos, PhD – UMC Groningen – The Netherlands
This is one of the best technologies for our end stage patient. Prof. Dr. med. Felix Herth, FCCP – UniversitätsKlinikum Heidelberg – Germany
In the right patient, the Zephyr is always going to be my first choice. Dr. Pallav Shah, MD – Royal Brompton & Harefield London – United Kingdom
How it works
Using a standard bronchoscope, Zephyr valves are delivered to target airways using a flexible delivery catheter
Once implanted, the one-way valve prevents airflow into the diseased region, while allowing trapped air and fluids to escape
Reducing the volume of the diseased region may allow healthier regions to expand and function more efficiently

The Zephyr endobronchial delivery catheter enables efficient and controlled delivery of the Zephyr valve

  • Proper valve sizing: The diameter gauges allow for a quick visual measurement of the bronchial diameter
  • Accurate positioning: A depth marker assists in positioning the catheter prior to valve deployment placement
  • Controlled delivery: An actuator lever facilitates precise deployment of the valve
