UMD: Stents designed for deployment into the esophagus to provide support for and/or maintain patency of the digestive tract . These devices may consist of a metallic (e.g., meshlike wire) or plastic tube, and they are available in several different shapes and sizes to adapt to particular sections of esophagus and/or to prevent migration; some include an antireflux valve. The stent surface may be coated to give the stent special capabilities. These stents are typically deployed using endoscopic procedures. Esophageal stents are used to bypass stenosis caused by benign diseases, injuries, or malignant tumors. They provide relief from difficulties in swallowing (i.e., dysphagia) and facilitate normal feeding.,NCI: A tube placed in the esophagus to keep a blocked area open so the patient can swallow soft food and liquids. Esophageal stents are made of metal mesh, plastic, or silicone, and may be used in the treatment of esophageal cancer.
