The segmented design fully conforms to the curvature of the esophagus, does not generate stress, and reduces the frequency of irritation to the esophageal wall at both ends of the stent.
Each segment of the stent is subjected to independent force and conforms to esophageal peristalsis. The stent always adheres to the esophageal wall and is not prone to displacement.
The stent is fully covered with film and crosses both ends of the stent by 5mm, greatly reducing the stimulation intensity on the tube wall at both ends of the stent and minimizing the incidence of restenosis
