DOUBLETM Esophageal Stent(Anti-reflux)

Indication

Preventing gastroesophageal reflux

Features

Double layered design with Anti-reflux skirt

PTFE skirt blocks gastric reflux with the stent placement at EG junction
Additional uncovered outer mesh helps to resist migration


Retrieval string

at proximal end helps repositioning

Radiopaque marker

4(four) at both ends & 2(two) in the middle


CONIOTM Esophageal Stent

Indication

Hypopharyngeal strictures

Small diameter with proximal head design

specially designed for refractory hypopharyngeal strictures


Silicone covering

Reduce the risk of tumor ingrowth

Visible green suture for easy removal

Radiopaque marker

4(four) at both ends & 2(two) in the middle

* Dr. Massimo Conio invented this stent and has treated patients with refractory hypopharyngeal strictures after combined therapy for laryngeal cancer

CERVICALTM Esophageal Stent

Indication

Upper esophageal strictures

Features

Short proximal head design

prevents damage of vocal cords in cases of stent placement close to the upper esophageal sphincter


Silicone covering

Reduce the risk of tumor ingrowth

Visible green suture for easy removal

Radiopaque marker

4(four) at both ends & 2(two) in the middle


BETATM Esophageal Stent

Indication

Leak or fistula after bariatric surgery

Features

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 reposition

Radiopaque marker

4(four) at both ends & 3(three) in the middle of each ring


MEGATM Esophageal Stent

Indication

Leak or fistula after sleeve gastrectomy

Features

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
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 position

Fully silicone covering allows easy removal

Radiopaque marker

4(four) at both ends & 2(two) in the middle
