Endobronchial valve

An endobronchial valve (EBV) is a small, one-way valve, which may be

bronchoscope in minimally invasive bronchoscopic lung volume reduction procedures in the treatment of severe emphysema
. The valves are also removable if they are not working properly.

Mechanism

The one-way endobronchial valve is typically implanted such that on

lung volume reduction surgery (though some people do not meet the eligibility requirements for one or both of these invasive procedures).[4][5]

History

Although endobronchial isolation techniques for emphysema were developed in the early 2000s,

minimally invasive alternative to lung volume reduction surgery for emphysema. In lung volume reduction surgery, one or more diseased portion(s) of a lung are excised. Endobronchial valves were designed to replicate the effects of that procedure without requiring incisions, by simply allowing the most diseased portions of the lung to collapse. Emphasys was purchased by Pulmonx in 2009, and Pulmonx currently markets the Zephyr® endobronchial valve (developed by Emphasys) in Europe, Australia, China and many other locations outside the U.S. Pulmonx also sells the Chartis® Pulmonary Assessment System, which is an assessment tool used with endobronchial valves to help physicians target appropriate lung compartments for treatment.[2]
Another company, Spiration (Seattle, Washington), developed a different type of endobronchial valve and was acquired by Olympus in 2010.
