Fistula-occuding Esophageal stents

The fully covered design can occlude the esophageal fistula effectively. And the spherical part in the middle of the stent can prevent side leakage effectively.

Made of single Nitinol wire with the “thermal memory effect” allowing the stent to expand to its preset shape after released.
Mesh structure and atraumatic ends to reduce irritations to the patient. 
Strong radial force and anatomy-fit spherical part in the middle helping to avoid migration.
Radiopaque marks for easy orientation and exact implantation under X-ray.
Resistant and elastic covering to avoid restenosis.
