Stents, Esophageal, Metallic
Definition : Esophageal stents manufactured from metallic alloys, such as stainless steel, platinum, or nickel titanium alloys (e.g., nitinol). These devices typically consist of a metallic (e.g., meshlike wire) tube. Most stents include a plastic covering to resist tumor ingrowth and/or to seal esophageal fistula. Metallic stents used in the esophagus are usually deployed under local anesthetics using endoscopic procedures (i.e., esophagoscopy). Metallic esophageal stents are permanent devices mostly used to treat stenosis caused by malignant tumors. They could also be used for injuries and/or benign diseases.
