Nonvascular Stent

Esophagus Stent of Memory Alloy

1) Esophagus stent of memory alloy has fine biocompatibility and corrosion resistance, and it also has special characteristics of memory and superelasticity. Under 0~10℃ (ice water), the stent is soft and its shape can be changed to a certain extent. Put it into the delivery device of esophagus stent and the stent would restore to its original shape after being released. It would generate soft and lasting radial expansion to the inner wall of the esophagus, restoring the narrow parts to normal state. 

2) The stent shows fine superelasticity under body temperature and can move with the normal peristalsis of the esophagus, restoring the esophagus to its normal state without generating any discomfort. 

3) Both ends of the inner stent are in the form of round arc, avoiding damaging the walls of esophagus. The flares end of the stent is closed stuck to the inner wall of esophagus, avoiding any displacement. It’s easy to operate and its effectiveness is obvious.

4
) The surface of the stent is covered with medical silicon rubber film, which effectively prevents the growth of granulation on the walls of esophagus and the backflow of stomach liquid or food.
