Enteral Self-Expanding Metal Stent (SEMS)

A single-wire-design self-expanding Nitinol stent (SEMS) used to relieve malignant strictures in the esophagus, colon or duodenum.

In which cases?

Malignant dysphagia, where an oesophageal stent restores swallowing.
Malignant colonic obstruction, as palliation or as a bridge to surgery.
Gastric outlet or duodenal obstruction in a patient who cannot be operated on.
An oesophageal fistula that has to be sealed with a covered stent.

What makes it different?

Nitinol expands at body temperature and holds a steady radial force on the stricture.
Woven from one wire, so there is no cut end sitting against the wall.
Radiopaque markers, so both stent ends are placed under fluoroscopy.
Uncovered, partially covered and fully covered versions, chosen against ingrowth and migration.
