DEVICE: Esophageal TTS Stent (08809744973449)

A non-bioabsorbable, expandable, tubular device intended to be implanted into the oesophagus to maintain luminal patency in strictures, prevent tumour in-growth, seal oesophageal fistulas, reduce acute bleeding from oesophageal varices, and/or to treat other lesions causing oesophageal leakage (e.g., anastomotic). It consists of a mesh structure made of metal which is covered/lined with a synthetic polymer material (e.g., silicone) that prevents lateral flow and tissue ingrowth and facilitates removability. It is typically expanded in situ (e.g., self-expands) and disposable devices intended to assist implantation may be included.
