For endoscopic closure of segmental and subsegmental bronchi
- Quick closure in acute situations
- Conical shape with studs on the outside
- Made of implantable silicone (> 29 days)
- Developed in close collaboration with Dr. Yoichi Watanabe, Okayama, Japan
- Bleeding of the segmental or subsegmental bronchi
“Spigots represent a relatively simple method of segmental blockage in the presence of bleeding for bridging the acute situation until a definitive local therapy can be introduced.”

EWS™ offer the benefit of a targeted closure at the (sub)segment level, whereby the ventilation of adjacent areas is not hindered.
Safe and durable
A study of 63 patients in Japan, including 40 cases of non-treatable pneumothorax, 12 cases of pyothorax with a fistula and 7 cases of pulmonary fistula, has shown that the use of EWS™ is safer and delivers longer lasting positive results than conventional methods.
After locating the affected bronchi with a balloon catheter (alternative x-ray, etc.), the EWS™ is positioned using a flexible bronchoscope and forceps that are guided through the working channel of the bronchoscope. EWS™ was successfully positioned in 96.7% of cases. The air loss was stopped or significantly reduced in 77.6% of cases. No serious complications occured.1
