  • Patent number: 6010520
    Abstract: A double tapered esophageal dilator bougie is designed to be disposable after a single use, is radiopaque, and is tapered at both ends to different respective dilator circumferences. Each end of the dilator bougie tapers to two different French sizes available on each end, with one end of the dilator being smaller than the other end. The dilator bougies are produced in graduated sizes and can be packaged as a kit of five. Each bougie in the kit of five is made of a similar PVC material, but the durometer of the PVC decreases as the bougie size increases. This allows each bougie in the kit to have a similar flexibility despite differences in circumference. A central guide wire channel extends the length of each dilator bougie for optional use with a positional guide wire.
