Characteristics:
The stent will engender a continued gentle radial tensile force, acting on the inner wall of esophageal to expand the stenosis gradually and rebuilt the unobstructed passage.
The covered structure effectively avoids the tumor tissue ingrowth ,reducing the possibility of second stenosis.
Lasso in the near-end of the stent, easy to be recycled. Anti-reflux stents can be chosen to effectively restrain the gastroesophageal reflux disease .
