EWS® — Silicone spigots for segmental and subsegmental bronchi

Endobronchial Watanabe Spigots (EWS®) were developed by NOVATECH in close cooperation with Dr. Y. Watanabe, Okayama, Japan. They are made of implant-grade silicone (implantable for more than 29 days), radio-opaque, sterile and blister-packed (3 EWS per blister).

For re-expansion of the lung in case of:

  • Inoperable pneumothorax
  • Bronchio-pleural fistula with a continuous loss of air and collapse of the lung despite thoracic suction drain, when surgical intervention is not indicated
  • Continuous bleeding from a subsegmental or segmental bronchus).

A study performed in Japan with 63 patients including 40 cases of intractable pneumothorax, 12 cases of pyothorax with fistula and 7 cases of pulmonary fistula has shown that using EWS® is safer and has more permanent results than conventional methods.
