Study Design/Materials and Methods The aim of this experimental study was to investigate the effect of Nd:YAG laser on metallic trachebronchial stents, because Nd:YAG laser could be used for resection of tumourous tissue growing through stent meshes (Strecker‐, Palmaz‐, Wallstent). Study Design/Materials and Methods: An in vitro worst‐case‐model was used to investigate the effects of different types of laser application on metallic stents: non‐contact application, and contact application with bare fibres and with hemispherical sapphires. Results In the non‐contact method and with bare fibres stent destruction occurred at power settings exceeding 10 W, whereas in the contact method with hemispherical sapphires power settings of 20 W were possible without stent damage.
