The Danis Seal is a fully covered self-expandable nitinol esophageal stent for the treatment of esophageal leaks and ruptures. The large diameter with optimal length and expansion force, durable silicone coating and special anti-migration design make this stent the ideal solution in appropriate situations.


The Danis Seal is indicated for patients aged 18 and older and is indicated for the treatment of esophageal or gastric leakage from:

  • Anastomotic wound dehiscence (after esophagectomy, gastric bypass),
  • Esophageal ruptures / perforations (spontaneous rupture - Boerhaave’s syndrome; iatrogenic rupture / perforation occurring during esophageal dilations, endoscopic manipulations, traumatic esophageal ruptures due to blunt thoracic trauma).

Features / Benefits

The wide diameter of the Danis Seal helps to optimally adhere to the esophageal wall.
The unique design of braiding of this stent is adapted to esophageal peristalsis and, together with enlarged flares, reduces the risk of migration. The uncovered stent edges allow tissue ingrowth, helping to seal the space between the stent and the tissue.
The stent has a high-strength, acid-resistant retrieval loop at both ends that allows the stent to be safely and ergonomically removed from the esophagus.
The Danis Seal is fully covered with durable silicone, which allows easy extraction and at the same time the cover protects the nitinol wires from contact with stomach acids and potential corrosion.
Platinum-iridium radiopaque markers located at both ends and in the center of the stent allow good visibility and accurate stent placement.
MRI compatibility - "MR Conditional", compatible with 1.5 Tesla and 3 Tesla static magnetic field.


The stent is delivered sterile and compressed in the delivery system. We recommend using a 0.035 ”(0.89 mm) / 220 cm ultra stiff guidewire for the implantation.
