A long, thin, flexible tube with an inflatable balloon at its distal tip intended to be used for gastrointestinal and/or biliary intraluminal dilation; it is typically used to endoscopically dilate strictures of the oesophagus, pylorus, colon and/or biliary tract. The balloon is inflated to its prescribed diameter to widen the affected passage of the tract. The device may consist of one or more lumen, and may be of the fixed-wire or wire-guided type. This is a single-use device.
