The Tangent endoscope is a game-changer for accessing challenging anatomy.
Its low-profile outer diameter significantly increases my chance of cannulating the biliary tree through even a small cystic duct. This capability, combined with incredible optics and a large working channel that accepts all standard baskets, wires, and biopsy forceps, makes the Tangent an indispensable tool for advanced endoscopic procedures. The plug-and-play interface is the final touch of convenience.

The symmetric handle is the most exciting aspect of the endoscope.
For an interventional radiologist like me, the symmetric handle is the most exciting aspect of the endoscope, as it will allow more seamless use with either hand. That, coupled with thoughtful placement of the other components of the handle, should translate into more intuitive and tangle-free procedures. Add in an evolutionary step up in high-definition imaging, and this endoscope is tough to beat.
