Universal Stylet Bougie (USB)

The Universal Stylet Bougie, or USB™, represents a significant advance in the design and development of tracheal introducers (bougies) and stylets. Traditionally, the design requirements of stylets and bougies were considered incompatible—stylets require rigidity to manipulate and maintain a variety of angles, while bougies require flexibility for positive tracheal ring feedback and precise placement feedback while incorporating specific memory characteristics to allow correct placement.

The USB's unique design incorporates two metal inserts with different and distinct properties either side of a more flexible middle section. The USB can easily be manipulated to a variety of angles when used as a stylet, yet has the flexibility when used as a bougie to provide a significantly enhanced level of tracheal ring feedback.

In addition, the hexagonal shape provides less contact with the inner surface of the tracheal tube, providing particularly easy insertion and removal.
