Polymeric oesophageal stent, non-bioabsorbable

Polymeric oesophageal stents are tubular, mesh-like devices made entirely of synthetic polymers like silicone, designed to be placed inside the oesophagus. They are used to keep the passage open in cases of strictures (narrowing), achalasia (muscle dysfunction), or leaks, while also helping to seal fistulas or treat other obstructions. These stents expand within the oesophagus to maintain patency and are typically self-expanding, meaning they deploy naturally once positioned.

These devices are generally classified as single-use and are intended for temporary use, though regulations vary by jurisdiction. They may come with disposable tools to assist in placement, and their design—whether covered or uncovered—can influence clinical use. Always check local regulatory requirements before selecting or using one, as approval and classification depend on the specific device and market.
