Niti-S™ Esophageal Mega Stent

Mega™ (Post Sleeve Gastrectomy)

Category: Esophageal Stent  

A fully covered stent with a unique anti-migration design second outer cage. To treat malignant strictures


Malignant esophageal strictures

Visualization of the proximal tumor margin

  • Accurate stent positioning
    Proximal part is released earlier than its distal part to enable placement with consideration of the proximal tumor margin without fluoroscope
    Recommended for upper esophageal strictures
  • Deployment procedure
    Once the delivery system is in the correct position for deployment, Unlock the proximal valve of Y-connector, and hold the Y-connector, then push the hub toward tip
  • *Proximal release delivery system is available with S, Double™, Cervical™, Conio™.
  • Specially designed soft and flexible body: Adapts to the acute anatomy after sleeve gastrectomy
  • The diversion of the fistula by the placement of a covered stent is necessary in most cases and it re-establishes the continuity of the digestive tract and promotes healing of the fistula. Also, allows the early reintroduction of food, improving patient nutritional states and therefore favoring recovery
  • Large diameter and long length of the stent: Prevent migration
  • Proximal part of the stent is located near the middle of the esophagus, and distal part of the stent is located in the gastric antral or in the first duodenal portion
  • Fully silicone covering allows easy removal
