esophageal stent

The stent is covered by medical polymer biological membrane with

tulip ends, ball ends, or cup ends to reduce chance of migration, it

has smmooth edge on both ends withyout acute angle or burr, it

also has characteristics as precision position and gradual strong

expanding radial force.

it is possible to carry out secondary positioning during releasing 

process (released  length of stent is no more than 80%

The sectional-type design make the stent better adapt to the bending

of the esophagus, without producing bending stress, thereby reducing

the possibility of stimulating the esophageal wall by two ends of the

stent
