Lumened wire-guided dilators are used primarily in the treatment of esophageal strictures. They are available single-use or reusable. Types include Savary-Gilliard® and American Dilation System dilators. The dilators have a central channel that accommodates a guidewire. They come in various diameters, but the guidewire channel remains consistently the same size. This channel requires brushing and flushing during manual cleaning. Healthmark’s CC2-100-200 Channel Brush is available for this purpose. The nylon bristles and sturdy thermoplastic shaft allows for smooth and effective passage through this lumen.
