Niti-S™ Esophageal Mega Stent

Mega™ (Post Sleeve Gastrectomy)

Category: Esophageal Stent  

For treatment of leak or fistula after sleeve gastrectomy


  • 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
  • Removal sutures at both ends
