Esophageal stent
Esophageal stents are important tools for palliative treatment of inoperable esophageal malignancies. With the development of multiple self-expandable stents, there are now several therapeutic options for managing benign and malignant esophageal diseases. This paper discusses the various types of esophageal stents currently available, indications for their placement, challenges and complications that gastroenterologists face when placing these stents, and some of the innovations that will become available in the near future.

Stent System Structure Sketch
As to the covering ways,please refer to the “covering instruction of esophagus stent”
Covering instruction of esophagus stent
Conventional covering pattern
a. Uncovered
b. Ma (Partially covered)
c. Mb (Partially covered)
d. Mc (fully covered)
We also can offer follow customized covering pattern service:
e. Md (Partially covered)
f. Me (Partially covered)
g. Mf (Partially covered)
h. Mg (Partially covered)
Usage:
Be used to dilate the esophagus,cardia and anastomotic stoma stenosis and plug esophageal fistula.
Characteristics:
1. 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.
2. The covered structure effectively avoids the tumor tissue ingrowth, reducing the possibility of second stenosis.
3. Lasso in the near-end of the stent, easy to be recycled.
4. Anti-refulx stents can be chosen to effectively restrain the gastroesophageal reflux disease.
Remark:
Gridding parts in the pictures means covered parts.
