Their structures, strengths and weaknesses were analyzed. A new woven artificial tracheal stent that used leno-based construction was designed and fabricated at last. Additionally, a preliminary mechanical study was carried out on the new artificial tracheal stent, such as the radial supporting force and the elastic restoring force, making foundation for application of the new artificial tracheal stent.展开更多
