Esophageal Stents

Niti-S BETA Esophageal Stent is used for leak or fistula after bariatric surgery.

● Unique design : PTFE covered body and silicone covered outer double layers
   – Body : PTFE membrane with unfixed cell construction provides excellent flexibility and conformability to fit in tortuous anatomy
   – Outer double layers : Silicone covered double layers prevent the risk of migration and any substance to contact the leak or fistula
● Both distal and proximal retrieval strings help for easy removal or repositioning
● Radiopaque marker : Four (4) at both ends & Three (3) in the middle of each ring

Niti-S CERVICAL Esophageal Stent is used upper esophageal strictures.

● The short proximal head design prevents damage to the vocal cords in cases of stent placement close to the upper esophageal sphincter
● Silicone covering reduces the risk of tumor in-growth
● Visible green suture for easy removal
● Radiopaque marker : Four (4) at both ends & Two (2) in the middle

Niti-S CONIO Esophageal Stent is used hypopharyngeal strictures.

● Small diameter with a proximal head design 
– specially designed for refractory hypopharyngeal strictures
● Silicone covering reduces the risk of tumor in-growth
● Visible green suture for easy removal
● Radiopaque marker : Four (4) at both ends & Two (2) in the middle

Niti-S CONIO Ⅱ Esophageal Stent is benign and malignant upper, middle esophageal stricture.

HEAD – Silicone-covered S type for better palliation and 2mm bigger than the body

BODY – Conformable D type with PTFE membrane to prevent stent-related complications.

BUMPER – Silicone-coated Double ring for anti-migration, 6mm bigger than the body at the peak and the diameter of the hole is 2mm.

Niti-S™ DOUBLE™ Anti-Reflux Esophageal Stent is preventing gastroesophageal reflux.

● Double-layered design with an anti-reflux skirt
– The PTFE skirt blocks gastric reflux with the stent placement at the EG junction
– The additional uncovered outer mesh helps to resist migration
● Retrieval string at proximal end helps repositioning
● Radiopaque marker : Four (4) at both ends & Two (2) in the middle

Niti-S DOUBLE Esophageal Stent is used for malignant esophageal strictures.

● Double-layered design
– Silicone full covering prevents the risk of tumor in-growth
– The additional uncovered outer mesh helps to resist migration
● Retrieval string at the proximal end helps repositioning
● Radiopaque marker : Four (4) at both ends & Two (2) in the middle

Niti-S DUAL Esophageal Stent is for benign and malignant esophageal stricture

● Gentle Radial Force : less painful after stent insertion
● Conformable Stent Structure : enables stent to conform to the esophagus movement
● Dual Structure : minimal foreshortening led to accurate stent positioning
● Radiopaque Marker : Four (4) at both ends of the flanges & Two (2) at both ends of the body of the stent

Niti-S MEGA Esophageal Stent is used for 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 reestablishes 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
– The proximal part of the stent is located near the middle of the esophagus and the distal part of the stent is located in the gastric antral or in the first duodenal portion
● Full silicone covering allows easy removal
● Radiopaque marker : Four (4) at both ends & Two (2) in the middle

Niti-S Proximal Release Delivery System for Esophageal Stent

Visualization of the proximal tumor margin 
● Accurate stent positioning
– The 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 the Y-connector, hold the Y-connector, and then push the hub towards the tip

S Esophageal is a Dumbell-shaped Silicone-covered S type stent comes in various sizes and covering options.

Main Characteristics:

• Fixed cell with braided construction for  High flexibility and optimal radial force and both head ends (8mm larger than trunk) help to minimize migration
• Silicone covering and soft round ends to reduce tissue in-growth and hyperplasia reaction
• Visible green suture for easy removal
•  Radiopaque marker : Four (4) at both ends & Two (2) in the middle

Through The Scope (TTS) S Esophageal Stent

Easy and Simple Stenting through the scope channel
● Preloaded in a 10.5Fr delivery system for esophageal fully covered/partially covered stent
● The practical solution for tight, narrow or tortuous anatomies
● Proximal retrieval string may help removal of the stent
● Silicone coating designed to resist tissue in-growth
● Yellow marker on the black inner sheath for accurate placement under endoscopic visualization
● Radiopaque marker : Four (4) at both ends & Two (2) in the middle
