Pulmonx has developed the Zephyr Endobronchial Valve, a minimally invasive treatment for COPD/emphysema. The one-time procedure is done by bronchoscopy and requires no cutting or incisions. During the procedure, on average 4 tiny valves are placed in the airways to block off the diseased parts of the lung which allows trapped air to escape until the lobe is reduced. Reducing hyperinflation allows the healthier parts of the lungs to expand and take in more air. This results in patients being able to breathe easier and have less shortness of breath.1 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.11. Criner G et al AM J Resp Crit Care Med 2018, Published on 22-May-2018 as 10.1164/rccm.201803-0590OCBrief 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.
