Abstract
A wire-guided esophageal bougie comprises a PTFE-lined, silicone rubber tube with a tapered, silicone rubber dilator on its distal end, the dilator being more flexible than the PTFE-lined tube. Radiopaque material throughout the length of the tube renders it fluoroscopically visible in the esophagus while a radiopaque ring in the dilator fluoroscopically locates the position of the dilator relative to a stricture.
